This communication describes a method for the solid phase extraction of phencyclidine (PCP) from urine, followed by GC/MS analysis. The method is linear over the range 5-1000 ng/mL and consistently produces cleaner chromatograms than can be obtained by liquid-liquid extraction. The limits of detection and quantitation are 0.47 and 1.38 ng/mL, respectively. Extraction efficiency, or recovery, was found to be 100.8 +/- 6.5%, and the between-run precision was 3.5% (25 ng/mL, n = 51). This solid phase method for extraction of PCP from urine has several advantages over liquid-liquid extraction for laboratories of any size. |
