The report gives results of an investigation, under laboratory conditions, to determine the extent and cause of weight losses first noticed in field situations on Andersen impactor fiberglass substrates. The investigation results indicated that, if performed carefully throughout, sample acquisition results in a weight loss of no more than 0.20 mg per stage. Such a loss is not of major consequence when more than 2-3 mg is collected on a stage; however, it could represent a serious error at less than 2-3 mg. Incomplete drying and careless handling were found to be the major sources of weight loss.
