Migration of microplastics from food contact materials & packaging

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.

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.

Cyclosiloxanes are the primary building blocks of siloxane polymers and, ultimately, silicone rubber. Hence, cyclosiloxanes can remain in the final silicone article as residual impurities. Several cyclosiloxanes (D4, D5, D6; see table below) are considered harmful to the environment and human health. These three substances are listed in the REACH Candidate List of substances of very high concern (SVHC). Substance Abbreviation CAS N:o Octamethylcyclotetrasiloxane D4 556-67-2 Decamethylcyclopentasiloxane D5 541-02-6 Dodecamethylcyclohexasiloxane D6 540-97-6 The Nordic Swan Ecolabel criteria for greaseproof paper sets the limit values for D4, D5, and D6 impurities in silicone coating as 400 ppm per substance and 1000 ppm for the sum of D4, D5, and D6. In addition to the restricted substances listed above, this analysis package includes the quantification of cyclosiloxanes D3, D7, and D8.
