Determination of Methamidophos in Human Serum by Gas Chromatography With Flame Photometric Detector / 环境与健康杂志

ABSTRACT

Objective To establish a simple and quick method to determine methamidophos in human serum samples. Methods The samples were extracted by acetone and were separated with centrifuge then were determined by gas chromatography (GC-FPD). Results The determine limit for methamidophos in human serum was 0.05 ng. The minimum determine concentration was 0.40 ?g/ml. Rate of recovery of methamidophos added in human serum were 90.5%-105.6%. The relative standard deviations (RSD) were 4.52%-6.63%. Conclusion This method is sensitive, accurate and reliable for the determination of methamidophos in human serum samples.
