Air Sampling cassettes

Air sampling cassettes

LCS Laboratory offers filters, cassettes, impingers, derivatizing solutions and sampling pumps for measurement of mono- and poly- isocyanates.  The procedure as unique because unlike other methods, allows measuring of ALL, even unknown isocyanates.



Isocyanate vapor and mist are collected on 25 mm glass fibre filter spiked with 1-(9-anthracenylmethyl)piperazine (MAP). MAP reacts with isocyanate group, and produces nonvolatile derivative, thus preserving isocyanate for laboratory testing. Samples are collected at flow rate from 1 to 2 L/min to the total air volume from 15 to 500L. Estimated detection limit is 0.1 ug/sample

NIOSH 5525 offers different sampling  techniques suitable for short and/or time weighed average sampling. Samples can be collected on 37mm, 25mm, IOM’s, 13mm filters and impingers.  The best part is that you don’t even need to know what kind of isocyanate is used. We still can measure it.
