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.
本通讯介绍了一种从尿液中固相萃取苯环己哌啶（PCP），随后进行气相色谱/质谱分析的方法。该方法在5-1000 ng/mL范围内呈线性，与液-液萃取相比，能持续产生更清洁的色谱图。检测限和定量限分别为0.47和1.38 ng/mL。萃取效率（即回收率）为100.8±6.5%，批间精密度为3.5%（25 ng/mL，n = 51）。对于任何规模的实验室，这种从尿液中固相萃取PCP的方法比液-液萃取具有多个优势。
