建立酱香型白酒中8种吡嗪化合物的液相色谱串联质谱检测方法。采用Gemini 5μC6-Phenyl 110A苯基柱(250 mm×4.6 mm)进行检测,8种吡嗪化合物在50~5000 ng/m L范围内呈良好线性关系,平均回收率为82.3%~107.3%,相对标准偏差为1.4%~4.4%,检出限为0.01~0.05mg/kg。方法快速、简单,适合于白酒中吡嗪化合物的分析。
To establish a method for the determination of eight pyrazine compounds in Maotai liquor by liquid chromatography-tandem mass spectrometry. Gemini 5μ C6-Phenyl 110A phenyl column (250 mm × 4.6 mm) was used for the detection. The eight pyrazine compounds showed a good linearity in the range of 50-5000 ng / mL with the average recoveries of 82.3% -107.3% The standard deviation was 1.4% ~ 4.4%, the detection limit was 0.01 ~ 0.05mg / kg. The method is rapid, simple and suitable for the analysis of pyrazine compounds in liquor.
