Measurement of biogenic or biobased carbon in the material or product as a percent of the total carbon or total organic carbon in the product. ASTM D6866 outlines two ways of expressing the proportion of material that originates from renewable resources. Biogenic carbon content indicates the proportion of total carbon (TC) originating from renewable resources. Alternatively, inorganic carbon can be removed before testing, and the result is then expressed in relation to total organic carbon (TOC), giving the biobased carbon content. An additional cost applies to the removal of inorganic carbon. The price is for non-volatile samples. If your sample is volatile, please discuss the suitability of your sample type with our experts. Please also note that we cannot accept samples that contain artificial carbon-12, carbon-13, or carbon-14 isotopes because they will cause damage to the equipment. Note! The results obtained for gaseous emissions should always be expressed as "biogenic carbon content" because the initial step of converting carbon to gaseous CO2 cannot be done when the carbon is already in gaseous form. Biobased carbon content determination by ASTM D6866 does not reveal how much of the sample's total weight originates from renewable sources. This can be estimated, however, by combining data on biobased carbon content with information on the total carbon content of the product. Biobased content measurement by EN 16785-1 may also be considered as an alternative.

Commission Regulation (EU) No 2023/915 specifies maximum levels for heavy metals in various foods, and Directive 2002/32/EC does the same for various feeds. This analysis can be used to quantify traces of the heavy metals lead (Pb), cadmium (Cd), arsenic (As), and mercury (Hg) in food, feed, and dietary supplements. The method applied is ICP-MS according to the EN 15763 standard.

Phase identification and quantification (Rietveld analysis) of a crystalline powder material using X-ray diffraction (XRD). The analysis can also provide unit cell dimensions. The analysis is only suitable for materials with at least one crystalline phase. The quantification accuracy is roughly 0.1 %, depending on the sample matrix and the phase in question. The available temperature range for XRD measurements is 25-1100 °C and the crystallinity can be studied as a function of temperatures. The measurements can be done under a normal atmosphere, inert gas, or vacuum. Please contact our experts to discuss the available temperature and atmosphere combinations. Please mention which crystalline phases your material contains and which ones are you interested in quantifying when requesting testing. However, the method can be applied to unknown phases as well. Either a tabletop or a synchrotron XRD can be used to perform the measurements.

Determination of carbon, hydrogen, nitrogen, sulfur, and oxygen content of an organic sample. CHNS analysis (”LECO analysis”) is performed using a flash combustion method, where the sample is combusted under 25 kPa of O2 at an elevated temperature (1000 °C), followed by gas chromatography separation and detection using a thermal conductivity detector. Oxygen is analyzed by reduction on granulated carbon at 1480 °C, utilizing high-temperature thermal decomposition and conversion of oxygen into carbon monoxide before gas chromatography separation and detection with a thermal conductivity detector. The sample can be either solid or liquid, but water in the sample affects the results. In the case of aqueous samples, it is possible to dry the sample before analysis. The price includes two parallel measurements. The results are reported as wt-% of the initial sample. The ash, drying and dry loss measurements will increase the minimum required sample material need to 300 mg. The analysis gives the total carbon, hydrogen, nitrogen, sulfur, and oxygen content of the material, but it does not identify any chemical structures. The measurement can be combined with other methods, such as GC-MS, 1H, and 13C NMR, to perform substance structure identification. Possible element packages: O, CHNS, and CHNOS.

XRF is a quantitative and qualitative method that can be used to analyze solid and liquid materials. This method is intended for a standard screening of homogeneous materials that do not require special sample preparation, precautions, or have any other special requirements. Wavelength-dispersive XRF (WDXRF) is used to perform the measurements unless energy-dispersive XRF (EDXRF) is specifically requested.

Time-of-Flight Elastic Recoil Detection Analysis (ToF-ERDA) measurement for determining the elemental concentrations of thin films. ToF-ERDA is capable of identifying all elements, including various hydrogen isotopes. It provides elemental depth profiles by determining the concentration of each element at different depths within a sample. Typically, the method achieves detection limits ranging from 0.1 to 0.5 atomic percent and depth resolution between 5 and 20 nm. It is suitable for analyzing films with thicknesses between 20 and 500 nm. For accurate measurements, the sample surface should be smooth, with a roughness of less than 10 nm. The method is inherently quantitative when analyzing thin films on typical substrates, such as silicon (Si), gallium nitride (GaN), silicon carbide (SiC), gallium arsenide (GaAs), or indium phosphide (InP). So, reference samples are not needed to obtain quantitative results. The technique is particularly useful when analyzing light elements due to its good detection limits. In addition to typical ToF-ERDA measurements, we also offer LI-ERDA (also referred to as Foil ERDA) for more precise determination of hydrogen isotopes. The detection limits with LI-ERDA are typically around 0.01 atomic percent, and depth resolutions of ~1nm can be achieved. LI-ERDA only allows detection of hydrogen isotopes.

MOSH and POSH have very similar structures and they tend to elute together in chromatography. Thus in polyolefin plastics and materials with polyolefin layers, it is usually impossible to separate MOSH and POSH with normal analysis techniques. The analysis includes a compliance assessment according to the following references: MOSH fraction: in-house risk assessment POSH fraction: Plastics Europe documentation Polyolefin oligomers: research project for risk assessment. MOAH fraction: Standing Committee on Plants, Animals, Food and Feed Section Novel Food and Toxicological Safety of the Food Chain 19 October 2022

Acrylamide is a food contaminant that forms from the naturally occurring constituents of the amino acid asparagine and reducing sugars, such as glucose and fructose, when food is prepared in low-moisture conditions at temperatures above 120 °C. The risk of acrylamide contamination is highest for baked and fried carbohydrate-rich foods whose raw materials contain its precursors, such as cereals, potatoes, and coffee beans. Commission Regulation (EU) 2017/2158 establishes mitigation measures to lower the levels of acrylamide in food and sets benchmark levels for acrylamide in different types of foodstuffs. The regulation mandates food business operators to undertake regular, risk-based sampling and analysis of acrylamide in the relevant product groups. Products with set benchmark levels include a variety of processed potato and cereal products, coffee products, baby foods, and cereal products for infants and young children.

To ensure the traceability and safety of food and feed products, they should only be composed of and contain ingredients included in the list of ingredients. This includes not containing material originating from other plant, fungi, or animal species. The need of species verification might be relevant to: Plant-based raw materials and products (herbs, spices, fungi), Meat and meat products, Feed products based on meat. As with most cases of food adulteration, the species may be falsified to substitute expensive ingredients with less expensive ones. Non-intended ingredients may also end up in the product due to negligence or faulty production processes. Species determination is performed using PCR techniques that detect the DNA of species present in the food sample. Approaches can vary depending on the methodology: One of the most common approaches is to check whether the sample contains DNA of species that similar products are most commonly adulterated with. For example, a beef product claimed to contain only beef can be screened for the presence of pig, horse, and poultry DNA., Next-generation sequencing methods and Sanger sequencing can be applied to get more detailed information about the species present, including the relative species composition of the sample.. For a successful analysis, the sample must contain intact DNA. In highly processed food and feed items, there's a chance of the sample not containing enough intact DNA to perform analyses. Contact our experts for more information and a quote tailored to verifying the origin of your product.

The limit is based on the report "Nordiske Seminar- og Arbejdsrapporter 1993:557" by the Nordic Council of Ministers.

Nitrosamines are organic compounds formed by a nitrosating reaction between certain amines and nitrosating agents in acidic conditions. While they are not intentionally added to products, nitrosamines may end up in pharmaceuticals and cosmetics as impurities when manufacturing or storage conditions are conducive to their formation. As many nitrosamines are highly potent carcinogens, the European Medicines Agency (EMA) and the U.S. Food & Drug Administration (FDA) require pharmaceutical companies to assess the risk of nitrosamine impurity presence in pharmaceutical products, including Active Pharmaceutical Ingredients (APIs) and finished products. An updated list of maximum acceptable intake (AI) levels for known nitrosamine impurities to be monitored in Europe can be found in Appendix 1 to EMA's latest guidance document. For US rules, see the FDA's list of recommended AI limits. We can provide nitrosamine testing for various products and matrices. The displayed price example is for a routine analysis (non-GMP) of one sample including screening of the following nitrosamines: NDMA (N-Nitrosodimethylamine), NMEA (N-Nitrosomethylethylamine), NPYR (N-Nitrosopyrrolidine), NDEA (N-Nitrosodiethylamine), NPIP (N-Nitrosopiperidine), NMOR (N-Nitrosomorpholine), NDPA (N-Nitrosodi-n-propylamine), NDELA (N-Nitrosodiethanolamine), NDIPLA/NBHPA (N-Nitrosodiisopropanolamine).

Analysis for determining the content of respirable quartz and other forms of respirable crystalline silica in products and materials. The results can be used for labeling purposes and to facilitate the development of safer products. Crystalline silica/quartz is a common ingredient in building products and other materials containing or composed of stone, gravel, clay, or sand. Exposure to respirable silica for extended periods or high exposure for short periods causes silicosis and may lead to the development of lung cancer. This is why a binding limit value has been set for workplace exposure to respirable crystalline silica in EU countries. Ensuring that materials have a low quartz content is the most effective and cost-efficient way to prevent respirable quartz exposure. In EU countries, materials containing crystalline silica and other category 1 carcinogens are subject to a classification obligation, unless carcinogens are present in quantities below 0.1 % (w/w). Consequently, such products should include the warning “May cause lung cancer by inhalation” and “Causes damage to lungs”. The obligation applies to chemically modified mineral products that contain quartz. Additionally, industrial mineral producers (IMA) in the EU have decided that even non-modified mineral products should be classified based on their crystalline silica content (fine fraction), provided the content exceeds 1.0 wt.%. Please contact the expert team through the form below for more details on the analysis.

As defined in the EU honey directive 2001/110/EC, honey is the natural sweet substance produced by Apis mellifera bees from plant nectar or honeydew. Honey that is placed on the market in the EU must meet the composition criteria outlined in the directive and must not contain food additives or other additional ingredients. Honey adulteration through the addition of cheaper sugar syrups is a typical type of food fraud. In 2023, the EU’s Joint Research Centre published a technical report in which 46% of the analyzed samples showed signs of containing exogenous sugars. The declaration of botanical and geographical origin is also subject to adulteration, as honey sold under a protected designation is more valuable. Several techniques can be used for honey authenticity testing, often in combination: NMR (1H-NMR) can be used to obtain a chemical fingerprint of honey, providing information on the botanical and geographical origins, as well as possible addition of exogenous sugars., Pollen analysis with microscopy supplements NMR data on botanical and geographical origins., Stable isotope analysis (EA-IRMS) is used to determine whether honey has been extended with sugars from C4 plants, such as sugarcane or corn. It can also detect the addition of sugars from C3 plants to some extent., Methods based on liquid chromatography and high-resolution mass spectrometry (LC-HRMS) can be used to determine if honey contains exogenous oligosaccharides and, with additional precision, if honey has been extended with sugars from C3 plants, such as rice and sugar beet.. This honey authenticity testing package can be used to determine whether the sample meets the definitions and criteria set for honey in Council Directive 2001/110/EC. This includes confirming the botanical and geographical origin and checking the honey for extension with sugar syrups.

Determination of the biomass fraction of CO₂ emissions generated from mixed fuel incineration, as required by the EU Emissions Trading System (ETS). CO₂ originating from non-fossil sources like biomass has an emission factor of zero under EU ETS and is therefore not counted towards carbon emissions. This means that the biomass fraction of mixed fuels, such as municipal waste or solid recovered fuel (SRF), must be determined to calculate reportable emissions accurately. In this analysis, the proportion of biogenic carbon dioxide in total emitted CO₂ from the incineration process is measured using the radiocarbon (¹⁴C) method. The measurement is based on the ASTM D6866 standard. This standard is equally rigorous and based on the same methodology as EN ISO 13833, which is mentioned in Commission Implementing Regulation (EU) 2018/2066 on the monitoring and reporting of greenhouse gas emissions. Testing is relevant for industrial plants that use mixed fuels and participate in emissions trading, as well as for municipal waste incineration (MWI) plants, which have been required to monitor and report emissions according to EU ETS since the beginning of 2024.

Determination of free fatty acids in fats and oils according to a titrimetric method outlined in EN ISO 660. The method can be adapted to other food samples through the addition of an extraction step, after which the acid value analysis is performed on the extracted fat or oil. The lower price of the displayed price range applies to fats and oils, while the higher one applies to samples that require extraction. There are many ways for free fatty acids to form in oils and fats. Some processing measures can increase the amount of free fatty acids, and a high water content may promote the hydrolysis of triacylglycerol, which increases the portion of free fatty acids. The general consensus is that elevated free fatty acid concentrations promote oxidation, which can be measured with parameters such as peroxide value and p-anisidine value.

Polymer products or materials often contain unreacted monomers left over from synthesis. These residual monomers can be toxic, influence the mechanical/rheological properties of the material, or contribute to unwanted odors or tastes. To prevent these effects, their concentration must be carefully monitored.  The analysis technique used for quantifying residual monomers greatly depends on the sample type. GC-FID, GC-MS, HPLC, and NMR are all techniques commonly used to determine the amount of residual monomers in polymer materials or solutions.  It is important to know exactly what monomers are used in the synthesis so that the measurement is properly calibrated and the specific molecules can be quantified. In some cases, it may be necessary to provide a pure sample of the monomers along with the finished material. Depending on the sample matrix and the monomers, our experts will choose the most appropriate analysis technique. Below are some considerations.  Gas chromatography (GC) methods require an extraction step to isolate the monomers from the polymer matrix. In cases of complex matrices, this preparation may result in the dilution of the sample and a corresponding increase in the limit of quantification (LoQ). , High-performance liquid chromatography (HPLC) methods can be used for materials containing non-volatile monomers or monomers with high molecular weights. , Nuclear magnetic resonance (NMR) spectroscopy allows for the quantification of monomers directly from a solution sample without the need for extraction. NMR is not as sensitive as GC methods, but can be used to monitor reaction kinetics or to provide additional information about the structure.. Viable matrices include solid polymers, aqueous/organic solutions, and dispersions. Other matrices may be accepted. Please contact our experts to receive a quotation tailored to your analysis needs.
