Method Development for the Determination of Diacetyl and Acetoin at a Microwave Popcorn Plant

Separate sampling and analytical methods for the determination of diacetyl and acetoin have been developed to assess workplace exposures at a popcorn processing facility have been described. Diacetyl (NMAM 2557) is efficiently recovered from an Anasorb CMS sampler tube when the composition of methanol in the desorption solvent is 1%, and acetoin (NMAM 2558) is efficiently recovered when the concentration of methanol is increased to 5%....
