【摘要】本文提出了一种新的生物样品前处理方法,与开管毛细管气相色谱法相结合,可以快速、灵敏、准确地测定生物样品中多种有机氯化物。已用于小白鼠脑、肝、肾样品的测定,结果令人满意。更多还原

【Abstract】 A novel procedure using Na2SO4 homogenization,HAc-HClO4 digestion followed by concentrated sulfuric acid and florisil column cleaning for pretreatment of biological samples in determination of trace organic chlorine compouds was developed. In combination with an open tubular glass capillary column gas chromatography it can be used to determine various organic chlorine compounds in biological samples rapidly, sensitively and accurately with detection limits in the range of sub-ppt to ppb and recoveries over 80%.更多还原
