Phthalates are a group of chemicals widely used as plasticizers, which make plastics more flexible and durable. They have also been used as additives in products such as cosmetics and personal care items. Several phthalates have been identified as endocrine-disrupting agents or as chemicals toxic to reproduction. Exposure to phthalates can occur through: Oral exposure Food: Exposure occurs via migration from food packaging., Children's toys: Children often put toys in their mouths.., Inhalation: Breathing in dust from vinyl flooring or fragrances (like perfumes) can cause exposure to phthalates via inhalation., Skin contact: Phthalates present in cosmetics, lotions, and soaps can be absorbed through the skin..

Analysis for quantifying dioxins and furans (PCDD/F) in various packaging materials (e.g. food and cosmetics packaging) and their raw materials, including plastics, paper, and rubber. Dioxins and furans are a family of chlorine-containing chemicals considered bioaccumulating, persistent organic pollutants (POPs) that can be toxic even at low doses. While regulatory limits apply mainly to food and feed, packaging materials can be a source of indirect exposure to dioxins and furans. Recycled materials tend to pose relatively high risks, depending on the quality of the raw material and the effectiveness of the decontamination process. The following substances are included in the analysis: Dibenzo-p-dioxins (PCDDs) Polychlorinated dibenzofurans (PCDFs) 2,3,7,8-TCDD. 2,3,7,8-TCDF. 1,2,3,7,8-PeCDD. 1,2,3,7,8-PeCDF. 1,2,3,4,7,8-HxCDD. 2,3,4,7,8-PeCDF. 1,2,3,6,7,8-HxCDD. 1,2,3,4,7,8-HxCDF. 1,2,3,7,8,9-HxCDD. 1,2,3,6,7,8-HxCDF. 1,2,3,4,6,7,8-HpCDD. 1,2,3,7,8,9-HxCDF.

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. 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.

Please specify the following upon ordering the test: desired testing temperature (max. 200 °C), desired shear rate range (from 0,1 s^-1 to 100 s^-1). The set-up configuration of the rheometer can be chosen based on the sample type (the most common options are parallel plate and cone-and-plate). Do not hesitate to ask for a quote for a custom viscosity testing program. For example: temperatures from -20 to 600 °C, and shear rate ranges from 0,01 to 1,000 s^-1 are possible, as well as rotational and oscillatory measurements, time and temperature sweeps, etc.

Determination of the total organic fluorine (TOF) content in combustible materials using combustion ion chromatography (CIC). By default, TOF is analyzed as total fluorine (TF). If required, total inorganic fluorine (TIF) can be measured as well, and TOF calculated as the difference between TF and TIF. TOF analysis gives information about the total amount of organic fluorinated compounds. It can also be used to evaluate the presence of per- and polyfluoroalkyl substances (PFAS) in the material, even though individual PFAS compounds can't be analyzed with this method. The analysis is suitable for many different materials. Please describe the sample in detail when requesting an offer to help us prepare a quote quickly.

XPS is a semi-quantitative technique used to measure the elemental composition of material surfaces. In addition, it can also determine the binding state of the atoms. XPS is a surface-sensitive technique. Typical probing depth is 3-9 nm, and detection limits range roughly between 0.1 and 1 atomic %. XPS can measure elements from Li to U. The elemental composition is reported in at.% and measured on 1 area of a few 100 µm. Upon request, we can measure smaller areas or depth profiles, and a binding state determination can also be provided. Measurements are typically performed using one of the following instruments: PHI Genesis, Thermo Fisher ESCALAB 250Xi, PHI Quantum 2000. Synchrotron XPS is also available.

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 (1,000 °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 displayed price includes the full CHNOS package with two parallel measurements and applies to conventional organic samples. The results are reported as wt-% of the initial sample. The addition of ash, drying, and dry loss measurements will increase the minimum required sample material 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. Analysis can be split into the following packages: CHN, O, and S.

Determination of mineral oil saturated hydrocarbons (MOSH) with polyolefin oligomeric saturated hydrocarbons (POSH) and mineral oil aromatic hydrocarbons (MOAH) in various matrices, including: Food contact materials (e.g., paper, board, plastics, rubber), Printing inks (incl. carbon black), Cosmetic products and raw materials, Lubricating oils and greases, white oils. The results are reported as the concentrations of fractions of MOSH/POSH and MOAH, with grouping based on the number of carbon atoms in the substances. The reported fractions are listed in the table below: MOSH/POSH (C10-C50), total MOAH (C10-C50), total MOSH/POSH (≥C10-≤C16) MOAH (≥C10-≤C16) MOSH/POSH (>C16-≤C20) MOAH (>C16-≤C25) MOSH/POSH (>C20-≤C25) MOAH (>C25-≤C35) MOSH/POSH (>C25-≤C35) MOAH (>C35-≤C50) MOSH/POSH (>C35-≤C40) MOSH/POSH (>C40-≤C50) In case the sample contains high amounts of MOSH, POSH, or poly alpha olefins (PAO), the levels should be indicated before shipping samples. Moreover, the LOQ is higher for samples with high MOSH, POSH, or PAO content due to dilution. Additionally, the safety data sheets (SDS) should be supplied with the samples when available.

Determination of the oxygen transmission rate of plastic films and sheet-like materials. The test is performed on two parallel samples simultaneously.
