广西中烟工业有限责任公司,南宁市北湖南路28号 530001摘要:为实现对混合物辛,癸酸甘油酯(ODO)的定量检测,建立了基于相对响应因子(RRF)的气相色谱-氢火焰离子化检测器(GC-FID)测定卷烟滤嘴爆珠中ODO含量(质量分数)的方法。1粒爆珠挤破后用正己烷提取,采......
A rapid micro-scale solid-phase micro-extraction (SPME) procedure coupled with gas-chromatography with flame ionized detector (GC-FID) was used to extract parts per billion levels of a principle basmati aroma compound 2-acetyl-1-pyrroline (2-AP) from bacterial samples. In present investigation,...
FID工作参数见表1。由表1可知,FID的空气和氢气流量满足配比要求,流量在点燃范围内,FID点火电压正常,因此FID燃烧工况稳定,但其输出电压偏高(33 pA)。采用万用表测试离子室和同轴电缆绝缘性能尚好,拆下收集器和喷嘴,发现绝缘瓷环表面微黄...

Unlike complicated thermal modulation methods that depend on rapid, delicately balanced heating and cooling, Agilent's GC x GC solution operates on a very simple principle of differential flow modulation. It uses a robust, proprietary Capillary Flow device interfaced to an auxiliary pneumatic control ...

systems. The combination of low mass and efficient heat transfer ensures that only a minimum of energy is required to heat and cool the module. Cooling is achieved using ambient air and small fans. Energy consumption can be cut by up to 98% using a MACH module. MACH construction principle...
GC-O 的原理非常简单,即在气相色谱柱末端安装分流口,将经GC 毛细管柱分离后得到的流出组分分流到检测器[如氢火焰离子检测器(FID)或质谱(MS)]和鼻子。当样品进入GC ,经由毛细管柱分离后,流出组分被分流阀分成两路,一路进入化学检测器(FID 或MS),另一路通过专用的传输线进入嗅探口。嗅探口通常是圆锥 ...

顶空气相色谱(HS-GC)法常用于七氟烷及HFIP的分析检测, 检测器主要使用FID[9]、 MS[10, 11, 12, 13]或ECD [14] 等。目前国内未见将HS-SPME应用于实际刑事案件中七氟烷及HFIP检测的报道。本文利用HS-SPME对挥发性复杂混合物的高富集能力及GC-MS强大定性能力对血液、尿液中的七氟烷及HFIP进行定性定量分析检测...
