Trap and separate both monomers and oligomers at the point of collection with the ISO-CHEK® filter-based sampling system. ISO-CHEK samples provide for highly sensitive physical and chemical characterizations of diisocyanates including HDI, MDI, IPDI, HMDI, 2,4-TDI, and 2,6-TDI. The IRSST developed ISO-CHEK to decrease sampling time to 15 minutes, reduce sample preparation and analysis time by 40%, and increase sample stability when compared to other methods. ISO-CHEK meets ASTM D5932 and D6561 specifications and is an ideal air sampling solution for OSHA's National Emphasis Program (NEP) on occupational exposure to isocyanates.
