SKC (environmental measurement) ISO-CHEK calibration standard solution (MAMA 2,4-TDI and 2,6-TDI concentrate, 1 g)

This is a calibration standard for ISO-CHEK(R), containing 1 gram of MAMA-2,4-TDI and 2,6-TDI.
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.
