| Abstract: | Solvent-extractable NIOSH charcoal tubes and thermally-desorbable Simtec Adsorba porous polymer monitors for trichloroethylene are compared for recovery efficiencies. The latter monitors are shown to have better recovery efficiencies with less variability than the charcoal monitors. Methods of distribution-free statistical evaluation are outlined for comparing monitors so that reliable conclusions can be drawn. |
