DETERMINATION OF PENTACHLOROPHENOL IN COMMERCIALLY PREPARED LYOPHILIZED HUMAN URINE CONTROL SAMPLES

Commercially available reference materials consisting of lyophilized h uman urine are routinely utilized by clinical chemists to monitor labo ratory performance for a variety of analyses. In this study commercial ly prepared lyophilized human urine control samples were reconstituted and analyzed for pentachlorophenol. Based on replicate analyses of tw o different reference materials, the levels of PCP in each were found to be representative of the levels typically present in urine samples collected from the general population of the province of Saskatchewan.
