毛细管气体色谱具有快速、高效的特点,是分析复杂和难分离物质对的有效工具。开展这方面的研究,除了需要专用的分析仪器外,毛细管柱的涂渍装置也是不可缺少的。国际上虽有少数厂家出售,但国内目前尚无这种仪器。我们以尾吹气作为气源,在气路中串一个气体六通阀,金属三通阀及针形调节阀,即可方便地将一台普通的上分-102型气体色谱仪改装成毛细管气体色谱分析和柱动态涂渍两用仪。
Capillary gas chromatography is fast and efficient, and is an effective tool for analyzing complex and difficult-to-separate pairs. To carry out research in this area, in addition to the need for specialized analytical instruments, capillary column coating device is also indispensable. Although a small number of international manufacturers for sale, but there is no such instrument at home. We use makeup gas as a gas source, a gas six-way valve, a metal three-way valve and a needle-shaped control valve in the gas line can be easily converted into a common upper -102 gas chromatograph capillary Gas chromatographic analysis and column dynamic coating dual-use instrument.
