DB-ALC2毛细管柱 血液中乙醇的测定顶空气相色谱法的详细介绍
血液中乙醇的测定顶空气相色谱法
血液中乙醇的测定顶空气相色谱法 详细信息:
本法利用乙醇的易挥发性,以叔丁醇为内标,用顶空气相色谱火焰离子化检测器进行检测,经与平行操作的乙醇对照品比较,以保留时间进行定性分析;以峰面积为依据,用内标法定量。

Determination of ethanol in blood. Headspace gas chromatography
Determination of ethanol in blood. Headspace gas chromatography. Details:
This method utilizes the volatility of ethanol, uses tert-butanol as the internal standard, and uses a headspace gas chromatography flame io nization detector for detection. After comparing with the ethanol reference substance operated in parallel, the retention time is used for qualitative analysis; As a basis, the internal standard method was used for quantification.
