【摘要】：目的分析血液腐敗后產(chǎn)生的乙醇及其他物質(zhì)并探討腐敗血液中乙醇的檢測(cè)及計(jì)算方法。方法以正常人空白血液制作腐敗血樣,采用1,4-二氧六環(huán)為內(nèi)標(biāo)物,通過頂空氣相色譜進(jìn)行定性及定量分析。結(jié)果血中乙醇在0.0625～1mg/mL范圍內(nèi)線性關(guān)系良好(r2=0.9996),各質(zhì)量濃度組的變異系數(shù)(CV%)2%,血中乙醇的最低檢出限為1μg/mL(S/N≥3)。腐敗血樣所產(chǎn)生乙醇與正丙醇的比例大致為25:1。結(jié)論檢驗(yàn)方法簡(jiǎn)便、準(zhǔn)確。為法醫(yī)毒化檢驗(yàn)相關(guān)工作提供了依據(jù)。
[Abstract]:Objective to analyze the ethanol and other substances produced after blood corruption and to explore the methods for the determination and calculation of ethanol in corrupt blood. Methods A corrupt blood sample was made from blank blood of normal people. 1,4-dioxane was used as internal standard and qualitative and quantitative analysis was carried out by headspace gas chromatography. Results the linearity of ethanol in blood was good in the range of 0.0625~1mg/mL (r _ 2 = 0.9996). The coefficient of variation (CV%) of each concentration group was 2%. The minimum detection limit of ethanol in blood was 1 渭 g / mL (Sin N 鈮，
