Heavy metal (Pb, Cd, As, Hg) analysis package

This metal screening analysis includes the semi-quantitative determination of 70 elements. The method can be used, for example, to determine the background concentrations of metals in environmental samples or to study the elemental distribution of unknown samples. Screening is also often performed to assess which metals should be analyzed by a quantitative method. The measurement is performed using a high-resolution ICP-MS technique (ICP-SFMS), which can identify very low elemental concentrations. A semi-quantitative determination of the following elements is included: Ag, Al, As, Au, B, Ba, Be, Bi, Br, Ca, Cd, Ce, Co, Cr, Cs, Cu, Dy, Er, Eu, Fe, Ga, Gd, Ge, Hf, Hg, Ho, I, Ir, K, La, Lu, Mg, Mn, Mo, Na, Nb, Nd, Ni, Os, P, Pb, Pd, Pr, Pt, Rb, Re, Rh, Ru, S, Sb, Sc, Se, Si, Sm, Sn, Sr, Ta, Tb, Te, Th, Ti, Tl, Tm, U, V, W, Y, Yb, Zn and Zr. However, please note that some elements may not be determinable due to matrix interference. During this semi-quantitative analysis, the instrument is calibrated for about 30 elements and the rest of the analytes are quantified using sensitivity factors for calibrated elements with similar mass and first ionization potential considering isotope abundances. Quantitative analysis is also available at an additional price. During this analysis, all elements are calibrated (excluding halogens and Os). Please ask for an offer for this service.

Determination of Be, Ba, Co, Al, Mg, Cu, Li, Mn, Ag, Sn, Ti, V, Zn, Tl, B, Hg, Mo, Fe, Ca, K, U, P, Cd, Na, Cr, Ni, Pb, Sb, As, and Se in water samples with ICP-MS-technique. The sample is homogenized and acidified (HNO3), after which the analysis is performed from the liquid phase. The displayed price applies to natural waters. If the sample contains a lot of solids or the matrix is significantly different from natural water (for example, wastewater and industrial waters), additional steps may be needed, and this will be reflected in the price. The concentration of each element is reported in µg/l.

Analysis package for dietary supplements. All supplement products must comply with maximum levels for heavy metals lead (Pb), cadmium (Cd), and mercury (Hg), as specified in Commission Regulation (EU) No 2023/915. Microbiological quality should also be assessed to ensure high-risk pathogens do not end up in the product. The displayed price includes the following analyses: Heavy metals (As, Cd, Hg, and Pb), Aerobic plate count, Yeasts and moulds, Escherichia coli, Coagulase-positive staphylococci, Salmonella in 25 g, Listeria monocytogenes in 25 g. Upon request, additional parameters can be added to the package at an additional cost. Commission Regulation (EU) No 2023/915 sets maximum levels for the following contaminants in certain supplement products: Citrinin in food supplements based on rice fermented with red yeast Monascus purpureus, Pyrrolizidine alkaloids in food supplements containing botanical preparations, including extracts and pollen based food supplements, Polycyclic aromatic hydrocarbons (PAH 4) in food supplements containing botanicals and their preparations, or propolius, royal jelly, spirulina, and their preparations. Other available analyses that can be relevant depending on product composition include: Additional microbiological parameters, such as presumptive Bacillus cereus, Mycotoxins, such as aflatoxins, Other plant alkaloids, such as tropane alkaloids and opium alkaloids, Pesticide residues, especially in supplements containing plant-based ingredients, Mineral oil hydrocarbons (MOSH/POSH and MOAH), Dioxins and PCBs, especially in supplements containing marine oils, Verification of the amount of active ingredients, such as vitamins, fatty acids, and amino acids.

Determination of total metal concentrations in a water sample using ICP-MS technology. The analysis package includes the elements Sb, As, Hg, Cd, Co, Cr, Cu, Pb, Ni, Zn, and V. The concentration of each element is expressed in µg/l. The method is suitable for various sample types, from natural waters to wastewater. However, for highly contaminated samples, the method's reporting limits may increase. More elements can be added to the analysis package upon request. We will be happy to prepare a customized offer for you.

Determination of elements in food, feed, and dietary supplements with ICP methods (ICP-MS, ICP-AAS, ICP-OES). Elements can contribute to the quality and properties of food and feed in several ways. Some are essential minerals that enhance nutritional value, while others (e.g., heavy metals) are considered undesirable contaminants with maximum levels set in EU food contaminant legislation. Some elements can also contribute to the sensory properties of products. Regulation (EU) No 1169/2011 allows the declaration of certain minerals if the food contains them in significant amounts in relation to daily reference intakes. The EU also keeps a database of authorized mineral additives in feed and regulates the allowed tolerances between declared amounts and analyzed amounts. Elements that are generally considered hazardous contaminants are regulated by Regulation (EU) No 2023/915 and Directive 2002/32/EC. The most common elements that are available for analysis include: Aluminium (Al), Arsenic (As), Boron (B), Cadmium (Cd), Cobalt (Co), Chromium (Cr), Iron (Fe), Manganese (Mn), Mercury (Hg), Nickel (Ni), Lead (Pb), Selenium (Se), Tin (Sn), Zinc (Zn), Molybdenum (Mb), Calcium (Ca), Phosphorus (P), Magnesium (Mg), Potassium (K), Sodium (Na), Titanium (Ti), Sulfur (S). It may be possible to analyze other minerals or heavy metals upon request. You can get more information on the analysis options and a quote for quantifying selected elements by contacting us.

Spark-OES is a commonly used method to determine the elemental composition of metals and alloys. The method provides a better alternative to other similar analysis techniques (ICP-OES, ICP-MS, XRF) due to its speed and low detection limits. All metallic elements and some non-metallic elements, such as C, N, and S, can be detected in the ppm range. The method is suitable for solid metal pieces with a minimum size of 1 x 1 cm. Sample preparation is included in the analysis.

UPLC-MS/MS analysis for determining the melatonin content in dietary supplements. According to Regulation (EU) No 432/2012, melatonin supplements may be marketed with the following health claims: "Melatonin contributes to the alleviation of subjective feelings of jet lag." The claim can be used if the product contains at least 0.5 mg of melatonin per portion., "Melatonin contributes to the reduction of time taken to fall asleep." The claim can be used if the product contains at least 1 mg of melatonin per portion..

Determination of starch in food with a spectrophotometric method.

Determination of microplastics present in food samples using Raman or FTIR microspectroscopy. The analysis report will specify different types of polymers by size (1-50 µm, 50–100 µm, 100–500 µm, >500 µm).

Determination of vitamin B7 (biotin) in food with an HPLC-UV-VIS method, or in supplements with a UPLC-MS/MS method. According to Regulation (EU) No 1169/2011, the biotin content of food products may be included in the nutrition declaration if it is present in significant amounts. The daily reference intake for biotin is 50 µg, and biotin content can be declared if the product contains at least: 7.5 µg/100 g or 100 ml in products other than beverages (15% of reference intake), 3.75 µg/100 ml in beverages (7.5% of reference intake), 7.5 µg per portion if the package contains a single portion (15% of reference intake). Foods that contain at least the above amounts of biotin can be labeled with the nutrition claim "Source of biotin." Additional nutrition and health claims related to vitamin B7 can be applied in accordance with Regulations (EC) No 1924/2006 and (EU) No 432/2012.
