SKC (environmental measurement) ISO-CHEK coated filter cassette (with derivative, 4 pieces)

This filter for the ISO-CHEK(R) Sampling System contains a Derivatizing Reagent and comes with a pre-loaded clear cassette and a jar containing the Derivatizing Solution (MOPIP in toluene).
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.
