Determination of total organic fluorine (TOF) in paper, polymers, textiles, and other combustible materials. Total fluorine (TF) content is measured first using combustion ion chromatography (CIC). Total inorganic fluorine (TIF) is then extracted and measured, after which TOF is calculated as the difference between TF and TIF. TOF analysis provides information about the total amount of organic fluorinated compounds in the material. It can also be used to evaluate the overall presence or absence of PFAS, even though individual PFAS compounds cannot be identified. Note: If the inorganic fluorine content of your samples is expected to be low, our total fluorine measurement may be a more cost-effective option as a PFAS proxy test.

Analysis to determine the concentrations of organic substances (pharmaceuticals and drug precursors) listed in the revised Urban Wastewater Treatment Directive (EU) 2024/3019. The analysis includes eight substances that can be very easily treated: Amisulprid (CAS: 71675-85-9), Carbamazepine (CAS: 298-46-4), Citalopram (CAS: 59729-33-8), Clarithromycin (CAS: 81103-11-9), Diclofenac (CAS: 15307-86-5), Hydrochlorothiazide (CAS: 58-93-5), Metoprolol (CAS: 37350-58-6), Venlafaxine (CAS: 93413-69-5). And four substances that can be easily disposed of: Benzotriazole (CAS: 95-14-7), Candesartan (CAS: 139481-59-7), Irbesartan (CAS: 138402-11-6), Mixture of 4-Methylbenzotriazole (CAS No 29878-31-7) and 5-methyl-benzotriazole (CAS No 136-85-6). An example test report (with mock data) illustrating the reporting format is available: Example report – Pharmaceuticals in treated wastewater. This method is suitable for treated wastewater samples with low total solids and dissolved solids content, but we also offer analyses for untreated wastewater. Please check the suitability of the sample matrix with the testing expert when requesting an offer.

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.

The analysis determines the concentration of substances listed in Annex I to Directive (EU) 2024/3019 on urban wastewater treatment. Substances that can be very easily treated: Amisulprid (CAS: 71675-85-9), Carbamazepine (CAS: 298-46-4), Citalopram (CAS: 59729-33-8), Clarithromycin (CAS: 81103-11-9), Diclofenac (CAS: 15307-86-5), Hydrochlorothiazide (CAS: 58-93-5), Metoprolol (CAS: 37350-58-6), Venlafaxine (CAS: 93413-69-5). Substances that can be easily disposed of: Benzotriazole (CAS: 95-14-7), Candesartan (CAS: 139481-59-7), Irbesartan (CAS: 138402-11-6), 4-Methylbenzotriazole (CAS No 29878-31-7), 5-methyl-benzotriazole (CAS No 136-85-6), The sum of 4-Methylbenzotriazole & 5-methyl-benzotriazole can be reported if requested. More compounds can be added to the analysis package upon request. This analysis is intended for untreated wastewater. We also offer an analysis with the same target analytes for treated wastewater to determine how effectively the substances are removed during the treatment process.
