A simple, analytlcal methodology has been developed for formaldehyde (CH20) moinltorlng using 13X molecular sieve as a sorbent medlum. Sleve sample pretreatment consists of a 20mln drying perlod sit 100-200 OC In an open-alr oven. Foilowing air sampling a CH20 determlnatlon Is performed by using a water-rinse desorption and pararosanlllne (colorimetric) analysls. Formaidehyde-exposedsleve samples can be stored In a sealed container for approximately 1 month with
