MAP

MAP – derivatizer used in NIOSH 5525 method

LCS Laboratory Inc., offers a new technique for the sampling and analysis of diisocyanate from air. The samples are collected following the  NIOSH 5525 procedure. The method is the most sensitive and the most versatile among all available techniques. Sensitivity as low as 0.05 ppb can be achieved for major diisocyanates. In addition this is the only standard method for sampling and analysis of poly-isocyanates.

Impingers

Air Sampling Impingers for area sampling

The samples can be collected on various filters: 37mm, 25mm, IOM’s and even by impingers.  Our laboratory offers sampling media free of charge as long as it is returned to our laboratory for analysis.

We analyze the samples using a dual detector UV and FLD- HPLC which results in unbeatable sensitivity of 0.1 ug/sample and a unique selectivity of the overall procedure. Samples can be collected at a flow rate from 1 to 2 L/min to a total volume of 500L. The method is suitable for analysis of total isocyanates used in the process, where an industrial sample of isocyanate is used as a reference material.
