气相色谱法测定猪肉、鱼和虾中三甲胺的含量

Determination of Trimethy lamine in Pork、Fish and shrimp by Gas Chromatography

采用气相色谱法，对猪肉、鱼和虾中的三甲胺含量进行测定并寻找了最佳测定条件。测得峰面积与三甲胺浓度在0－25μg/ml范围内呈良好的线性关系(γ=0.9999，n=6)，相对标准偏差为3.1％－5.9％，回收率为95.0％～97.7％，且该法操作简便、快速、准确。

In this paper we proposed a gas chromatographic method for the determination of trimethylamine in pork,fish and shrimp and disscussed the optimum conditions of quantitative analysis.The linear range between the peak area and the concentration of trimethylanine－N was 0－25μg/ml(γ=0.9999, n=6).The relative standard deviation was 3.1％－5.9％and the recovery was 95.0％－97.7％.This method was simple ,rapid and accurate.
