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. OCDD. 2,3,4,6,7,8-HxCDF. 1,2,3,4,6,7,8-HpCDF. 1,2,3,4,7,8,9-HpCDF. OCDF. Testing is often performed for the following reasons: Analyzing recycled PE, PP, and LDPE intended for cosmetics packaging according to CosPaTox guidelines., Analyzing paper and board bleached with elementary chlorine according to the requirements of TemaNord 2008:515 guidelines..

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.

Alkyl ketene dimers (AKD) are used as hydrophobic sizing agents in paper and board to improve water resistance. However, AKDs not bound by the fiber matrix can hydrolyse into dialkyl ketones (DAKs). For paper and board intended for food contact, BfR recommendation XXXVI states that DAK transfer into foodstuff may not exceed 5 mg/kg food. The package includes an analysis of the following substances from a food simulant: Substance Structure CAS No 16-Hentriacontanone (palmitone) C31H62O 502-73-8 16-Tritriacontanone C33H66O 15740-35-9 18-Pentatriacontanone (stearone) C35H70O 504-53-0 The analysis can be performed with the following simulants and approaches: Food simulant Type of testing Applicable standard Iso-octane Conventional migration EN 13130-1 Iso-octane Solvent extraction EN 15519 Tenax Conventional migration EN 14338

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.
