Dialkylketones (C16-C18 DAKs) migration from paper or board

Determination of bisphenol S (CAS 80-09-1) content in various matrices with LC-MS, including: Consumer goods made from plastic, elastomers, and rubber, Food packaging (plastic, paper, multi-materials). Testing is recommended especially for paper and board food packaging that contains recycled fibers and comes into contact with moist and fatty foods. To be compliant with German BfR Recommendation XXXVI, such packaging must not release bisphenol S into food in amounts exceeding 0.05 mg/kg. Extraction is possible with various techniques, including: Extraction method Intended purpose Standard (extraction) Suitable matrices Reporting limit Acetonitrile extraction Test for residual content of BPS In-house Plastic, rubber 0.003 mg/kg of sample Methanol extraction under sonication Test for residual content of BPS In-house Paper, board 0.01 mg/l of extract Cold water extraction Simulate migration into aqueous foods for non-coated paper EN 645 Paper, board 0.01 mg/l of extract Hot water extraction Simulate migration into aqueous foods for non-coated paper for baking purposes EN 647 Paper, board 0.01 mg/l of extract Solvent extraction Simulate migration into fatty foods for non-coated paper EN 15519 Paper, board 0.01 mg/l of extract

Acrylamide (CAS: 79-06-1) is used in certain sizing and retention agents in the production of fiber-based food packaging. It is classified as a potential human carcinogen, and its migration into food is restricted under several EU and national regulations. A migration limit of 0.01 mg/kg was recently introduced for acrylamide release from paper- and board-based food contact materials by the latest version of German BfR recommendation XXXVI (October 2025). The same limit also applies to migration from plastic food contact materials under Regulation (EU) No 10/2011. Specific migration from plastics or rubber can be determined using several food simulants. Paper and board, for which conventional migration testing is not suitable, are analyzed using aqueous or solvent extractions (EN 645, EN 647, EN 15519).

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.

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.

We offer several accredited methods for determining the total fluorine (TF) content of combustible materials: EN 14582, based on combustion ion chromatography (CIC). The method is recommended by the Nordic Council of Ministers as a quick and powerful total fluorine screening technique., EN 15408 using oxygen bomb combustion treatment followed by ion chromatography (IC). This method can be applied to plastic sheets and granules, and it is also possible to determine the total content of S, Cl, and Br., ASTM D7359-23, based on oxidative pyrohydrolytic combustion, followed by CIC.. The most suitable method is typically selected based on the sample matrix. However, please let us know if you wish a specific standard to be followed. Sample preparation (air drying and milling of the sample to particles <1 mm) is included in the displayed price.

Anthraquinone is an additive used in paper pulp manufacturing processes. According to BfR XXXVI, the application of anthraquinone as an additive to raw material is no longer recommended.

As there is no harmonized EU regulation for using wood in food contact applications, compliance should be assessed based on other resources, such as the national legislation of member states. This test package is based on the requirements of French Information note n°2012-93 (Note d'information n° 2012-93) for coated and non-coated wood intended for food contact. The following analyses are included in the displayed price: Test parameter Test method/standard Method of extraction or preparation Transfer of odor and flavor into food DIN 10955 Water extract or contact with model food Heavy metals in water extract (Pb, Cd, Hg) ICP-MS Cold or hot water extract (EN 645 / EN 647) Formaldehyde in water extract EN 1541 Cold or hot water extract (EN 645 / EN 647) Polychlorinated biphenyls (PCB28, PCB52, PCB101, PCB118, PCB153, PCB180) GC-MS In-house method Pentachlorophenol (PCP) content GC-MS CEN/TR 14823 In addition to the tests listed above, a pesticide screening should be performed for wood treated with antifungal substances (so-called "anti-blue" protection). The analysis covers 715 substances and is available for an additional cost of 298 EUR. In most cases, this test package is sufficient to establish food contact compliance of non-coated wood or articles thereof. If the wood has been coated with a lacquer or varnish, has been painted, or contains adhesives, complementary testing could be required (e.g., migration of primary aromatic amines, migration of mineral oil (MOSH/POSH and MOAH hydrocarbons). Our experts are happy to support you by reviewing the documentation of the coating material and/or the adhesive to determine the full scope of required testing.
