Total organic fluorine (TOF) content in paper, polymers, and textiles

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.

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.. For other listed matrices apart from cosmetics, the analysis package covers the following substances included in the REACH Authorization List: Substance Abbreviation CAS number Diisobutyl phthalate DIBP 84-69-5 Dibutyl phthalate DBP 84-74-2 Benzyl butyl phthalate BBP 85-68-7 Bis(2-ethylhexyl) phthalate DEHP 117-81-7 Di(n-octyl) phthalate DNOP 117-84-0 Diisononyl phthalate DINP 68515-48-0 Diisodecyl phthalate DIDP 26761-40-0 Products that contain restricted phthalates in concentrations higher than 0.1% may be removed from the market. The analysis package for cosmetic products contains the following phthalates: Substance Abbreviation CAS number Bis(2-ethylhexyl) phthalate DEHP 117-81-7 Benzyl butyl phthalate BBP 85-68-7 Dibutyl phthalate DBP 84-74-2 Diisononyl phthalate DINP 68515-48-0 Di(n-octyl) phthalate DNOP 117-84-0 Diisodecyl phthalate DIDP 26761-40-0 All the above-mentioned substances are prohibited in cosmetic products (Annex II of Regulation (EC) No 1223/2009).

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 oxygen transmission rate of plastic films and sheet-like materials. The test is performed on two parallel samples simultaneously. Measurement conditions (temperature and relative humidity) can be chosen according to the intended use of the material. Oxygen permeability is typically measured at 23 °C and 0% relative humidity as per standard ASTM D3985. In moist conditions, for example at 38 °C and 90% relative humidity, standard ASTM F1927 is used. Please disclose the desired temperature (from 10 °C to 38 °C) and relative humidity (either 0% or from 20% to 90%) upon ordering. This measurement is suitable for plastic films with OTR values between 0.05 to 20 000 cm³/(m² * day).

Extended analysis package for phthalates in various matrices using the GC-MS technique. Phthalates are a group of chemicals widely used as plasticizers, which make plastics more flexible and durable. Phthalates are also found as additives in products, including cosmetics and personal care items. Several phthalates have been identified as being endocrine-disrupting or toxic to reproduction. Exposure to phthalates can occur, e.g., through food (chemicals can transfer from packaging), children's toys (when put in their mouths), and dust from vinyl flooring. The following 43 compounds are detected as part of this analysis: Compound Abbreviation CAS number Phthalic anhydride - 85-44-9 Dimethyl phthalate DMP 0131-11-3 Diethyl phthalate DEP 84-66-2 Ethyl Isobutyl phthalate - 94491-96-0 Diallyl phthalate DAP 131-17-9 Dipropyl phthalate DPP2 131-16-8 Diisobutyl phthalate DIBP 84-69-5 Dibutyl phthalate DBP 84-74-2 Dimethylglycol phthalate DMEP 117-82-8 Diizopentyl phthalate DIPP 605-50-5 N-pentyl-isopentyl phthalate PIPP 84777-06-0 N-pentyl-isopentylphtalate - 776297-69-9 Di(2-ethoxyethyl) phthalate DEEP 605-54-9 Diamyl phthalate DPP 131-18-0 Tri-n-butylacetyl citrate - 77-90-7 Diisohexyl phthalate DMPP 146-50-9; 71850-09-4 Di(n-hexyl) phthalate DNHP 84-75-3 Butyl Octyl phthalate BOP 84-78-6 Adipic acid, bis(2-ethylhexyl) ester - 103-23-1; Ref.: 31920 Butyl benzyl phthalate BBP 85-68-7 Di( 2-ethylhexyl) phthalate DEHP 117-81-7 Di-n -hexyl azelate - 109-31-9 Dicyclohexyl phthalate DCHP 84-61-7 Di(n-octyl) phthalate DNOP 117-84-0 Dioctyl terephthalate DOTP 6422-86-2 Dibenzyl phthalate DBP2 523-31-9 Bis(2-propylheptyl) phthalate - 53306-54-0 Dinonyl phthalate DNP 84-76-4 Hexyl-2-ethylhexyl phthalate (HEHP) HEHP 75673-16-4 Diundecylphthalat - 3648-20-2 Bis(4-Methyl-2-pentyl)phthalate - 84-63-9 Diphenyl phthalate DPhP 84-62-8 1,2-benzenedicarboxylic acid, di-C6-8-branched alkyl ester, C7-rich DIHP 71888-89-6 Diisononyl phthalate DINP 28553-12-0; 68515-48-0 Diisodecylphtalate DIDP 26761-40-0; 68515-49-1 1,2-benzenedicarboxylic acid, dihexyl ester, branched and linear - 68515-50-4 1,2-benzenedicarboxylic acid, di C7-11 branched and linear alkyl esters DHNUP 68515-42-4 1,2-Benzenedicarboxylic acid, mixed decyl and hexyl and octyl diesters - 68648-93-1 1,2-Benzenedicarboxylic acid, di-C6-10-alkyl esters - 68515-51-5 Diisooctyl phthalate - 27554-26-3 Bis(6-methylheptyl) phthalate - 96507-86-7 1,2-cyclohexanedicarboxylic acid, diisononyl ester - 166412-78-8; Ref.: 45705 Dibutyl adipate - 105-99-7
