    1. PFAS Testing and Regulatory Support

      PFAS Testing and Regulatory Support

      Our scientists apply a range of PFAS analysis methods to identity and determine levels of PFAS in samples. Targeted PFAS analysis offers superior sensitivity and chemical specificity, enabling the precise quantification of the analytes at trace levels. However, this approach is inherently constrained by its scope, as it fails to account for unidentified and polymeric fluorinated compounds. To partially mitigate this limitation, the Total Oxidizable Precursor (TOP) assay is frequently integrated into analytical workflows. By utilizing an oxidation process, the TOP assay converts polyfluorinated precursors into measurable perfluorinated carboxylic acids (PFCAs), thereby providing a more representative estimate of the total PFAS environmental load in a sample. ISO 21675: - Water quality: Determination of per- and polyfluoroalkyl substances (PFAS) in water using solid phase extraction and LC MS/MS DIN 38414-14 - Determination of selected polyfluorinated compounds (PFC) in sludge, compost and soil DIN 38407-42 - Determination of selected polyfluorinated compounds (PFC) in water EN 17681-1 - Textiles and textile products - Per- and polyfluoroalkyl substances (PFAS) analysis of an alkaline extract DIN 3608 - Determination of perfluoroalkanoic acids by LC-MS/MS after oxidative digestion (TOP-Assay) Long chain PFAS chemical testing (C9-C21 LC-PFCAs) Custom semi-quantitative LC-MS/MS methods for selections of PFAS in multiple substances. Can be adapted to meet specific needs and sample types (examples include: hydrogen sector, electronics, personal care, polymers, foams). Non-targeted PFAS Analysis: This addresses the inherent limitations of (non-)targeted analyses, which fail to detect polymeric PFAS species.

    2. PG-50 Red Phosphorus Paste

      PG-50 Red Phosphorus Paste

      PG-50 is a microencapsulated red phosphorus flame retardant paste designed for use in coatings, epoxy systems, and polymer formulations that require high flame-retardant performance with safe handling and easy incorporation. Formulated as a ready-to-use, non-dusting paste, PG-50 eliminates the typical hazards of powdered red phosphorus while maintaining high phosphorus content (45–55 %) and excellent dispersion stability. The product provides high efficiency at low addition levels, is halogen-free, and complies with modern environmental and safety regulations such as RoHS and REACH.

    4. Phosphate Esters

      Phosphate Esters

      Phosphate esters are 100% active anionic surfactants which are produced as the free acid by either of two chemical routes. Phosphate esters are highly versatile surfactants offering a wide range of properties and applications. As such they are used widely in emulsion polymerisation, textile auxiliaries, maintenance chemicals, metal finishing, and many other applications. They are especially useful in household and maintenance cleaning products, where high active heavy duty products are required.
