SKC (environmental measurement) ISO-CHEK coated filter cassette (non-derivative, 12 pieces)

The coated filter, designated as the ISO-CHEK(R) Filter, consists of one PTFE filter coated with 9-(N-methylaminomethyl)anthracene (MAMA) and one glass fiber filter, pre-loaded into a 37 mm two-stage cassette for separating and collecting the vapor and particulate phases of isocyanate. Cat. No. 225-9050 is required for use. Please note that the Derivatizing Solution required for use with the ISO-CHEK(R) Sampling System is not included. For ISO-CHEK(R) cassettes containing the Derivatizing Solution, please refer to Cat. No. 225-9023 or 225-9023A.
ISO-CHEK is the only filter-based sampling system capable of simultaneously capturing and separating monomers and oligomers at the point of collection for diisocyanates, including HDI, MDI, IPDI, HMDI, 2,4-TDI, and 2,6-TDI, enabling highly sensitive physical and chemical characterization. Developed by IRSST, ISO-CHEK allows for rapid sampling in 15 minutes, offers excellent sample stability, and reduces sample preparation and analysis time by approximately 40% compared to other methods. It conforms to ASTM D5932-96 and D6561-00 standards.
