建立气相色谱内标法测定白酒中高级醇、酯类等6种物质的含量测定的分析方法。选用CP-Wax-57CB型分析柱,以乙酸正戊酯作为内标物,进行色谱分离,保留时间定性,内标法定量,结果表明回收率为90.07%~102.20%。该方法操作简便、快速,稳定可靠,回收率高,满足测定的需求。
To establish a gas chromatographic internal standard method for the determination of white spirit alcohol, esters and other six substances Determination of content analysis method. The CP-Wax-57CB analytical column was used. The n-amyl acetate was used as the internal standard for chromatographic separation. The retention time was qualitative and the internal standard method was used. The recovery was 90.07% -102.20%. The method is simple, rapid, stable and reliable, high recovery rate, to meet the needs of the determination.
