On-site comparison of the OSHA 47, Asset EZ4-NCO, Iso-Chek, DAN, and CIP10 methods for measuring methylene diphenyl diisocyanate (MDI) at an oriented-strand board (OSB) factory

Development and characterization of an adaptable aerosolized methylene diphenyl diisocyanate generation system

“…Our research team carried out method comparison studies in the workplace by focusing on processes that generate various typical isocyanate atmospheres. (28,29) These studies revealed trends in inter-method biases that seemed specific to the types of isocyanate emissions. However, the studies could not explain, with supporting evidence, certain biases observed between reference methods for which significantly similar measurements were expected.…”

Comprehensive methylene diphenyl diisocyanate (MDI) evaluation method comparison using a laboratory generation system

“…29,30 Our research team recently carried out studies comparing newer methods to older lter methods. 31,32 Although the biases could be explained for some methods, there was a reversal (negative vs. positive) between ISO 17734-1 (ref. 33) and ISO 14382, 34 depending on the type of isocyanate measured.…”

Total Reactive Isocyanate Group (TRIG) Measurement: A Commentary

“…Another reagent, 1,8-diaminonaphthalene (DAN) ( Bello and Streicher, 2013 ), converted all the isocyanate moieties to a single analyte, perimidone, without the need for a second reagent. DAN has given encouraging results when directly compared with other methods ( Aubin et al, 2020a , b ). However, there are concerns that DAN may not be suitable for the slower reacting aliphatic isocyanates.…”

“…The Capteur Individuel de Polluants CIP10M microorganism sampler ( Puscasu et al, 2015b , 2017 ) is another potential alternative to the impinger for mixed phased personal sampling as the solvent is contained. Studies have shown promising results when compared to impinger sampling ( Puscasu et al , 2014 ) but less so when compared to other methods such as the ASSET sampler ( Aubin et al, 2020a , b ).…”
