ISO-CHEK Design

The ISO-CHEK contains two filters for collecting different phases of the isocyanate.  A PTFE filter to collect the aerosol phase and an impregnated GFF to collect the vapor phase. 

After sampling, the PTFE filter is removed from the cassette and placed into a jar provided with a derivatizing solution* in order to preserve the isocyanate.

*  Derivatizing solution contains Methoxy-2-phenyl-1 piperazine reagent (MOPIP) in toluene.  See MSDS

Associated Analytical Methods:  ASTM D5932-96, ASTM D6562-00

Monomers vs. Oligomers

Unlike other Isocyanate testing methods, the ISO-CHEK can resolve the isocyanates present in monomers from the oligomers.    Usually only the monomers present are reported, but oligomers can be requested.  Call us for more details.
