Page 81 - Bevenue et al. (14) reported on the contribution of contaminants by organic solvents, glassware, plastic ware, cellulose extraction thimbles, filter paper, and silica gels to water samples causing interference with subsequent GC analysis in the ppb range. Prior to their use, heat treatment of glassware and the silica gels was recommended to eliminate contaminants, while plastic ware and filter paper were excluded from the procedure.
