目的　研究毒鼠强在三种 (极性、中等极性、非极性 )毛细管柱中的色谱行为 ,探索用三种毛细管柱在恒温和程序升温条件下测定毒鼠强的最佳条件。方法　火焰光度 -气相色谱法 (FPD -GC)。结果　在最佳条件下用三种毛细管柱测定毒鼠强标准品最低灵敏度分别达 6、10、12ng。结论　本法能满足日常食物中毒检测的需要 OBJECTIVE To study the chromatographic behavior of tetramine in three capillary columns (polar, moderate polar and nonpolar), and to explore the optimal conditions for the determination of tetramine in three kinds of capillary columns under constant temperature and programmed temperature. Methods Flame photometric-gas chromatography (FPD-GC). Results Under the optimal conditions, the lowest sensitivity of tetramine standards to 6, 10 and 12 ng, respectively, was determined by three capillary columns. Conclusion This method can meet the needs of daily food poisoning detection
