预分离柱/汽油含氧化合物测定
预分离柱/汽油含氧化合物测定 详细信息:
一直以来车用汽油中含氧化合物分析基本均采用ASTMD4815或SH/T0663的方法,但随着车用汽油产品标准GB/T17930-2006版的出台,ASTMD4815和SH/T0663两种方法存在着部分含氧化合物分离效果较差、甲醇检测限达不到要求的问题,因此该分析方法迫切需要改进。
浩瀚色谱(山东)应用技术开发有限公司提出采用多维气相色谱,利用经过硅烷化处理后的约1mTCEP微填柱和30mHH-1弹性毛细管柱,TCD和FID双检测器进行样品分离及检测,经过对柱系统和操作条件的优化,可准确地分析车用汽油中C1~C4醇类和醚类含氧化合物,甲醇检测限达到0.05%。方法重复性的相对标准偏差(RSD)≤0.827%,标准样品回收率在90%~110%之间。

Pre-separation column/gasoline oxygenate determination
Pre-Separation Column/Determination of Gasoline Oxygen Compounds Details:
The analysis of oxygenated compounds in automotive gasoline has basically adopted the method of ASTMD4815 or SH/T0663, but with the introduction of the automotive gasoline product standard GB/T17930-2006 version, the two methods of ASTMD4815 and SH/T0663 have some content. The separation effect of oxygen compounds is poor and the detection limit of methanol is not up to the required problem, so the analytical method urgently needs to be improved.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. proposes to use multidimensio nal gas chromatography, using a bout 1mTCEP micro-packed column and 30mHH-1 elastic capillary column after silanization treatment, TCD and FID dual detectors for sample separation and detection. The optimization of the column system and operating co nditions can accurately analyze C1-C4 alcohols and ether oxygen-co ntaining compounds in automotive gasoline, and the detection limit of methanol reaches 0.05%. The relative standard deviation (RSD) of method repeatability is less than or equal to 0.827%, and the recovery rate of standard samples is between 90% and 110%.
