Establishment of a Gas Chromatography Method for Detecting Six Types of Alcohol Substances
In this paper,gas chromatography was used to detect six types of alcohol substances.The sample was extracted by acetone oscillation and quantified by gas chromatography external standard method.Six target substances were separated within 40min,with all resolutions greater than 1.5 and a linear range of 5～500 μg/mL,with a correlation coefficient r2 of 0.999 0～0.999 9.The detection limit of the method was 0.001～0.002 g/kg,the quantitative limit of the method was 0.003～0.006 g/kg,the spiked recovery rate was 98.0％～109.8％,and the relative standard deviation(RSD)was 1.48％～7.43％.
