双通道多维色谱快速测定裂解气的组成

Quick Analysis of Cracked Gas by Gas Chromatograph with Two Signal Channels and Multi - column.

本文通过对色谱仪的气路系统和阀进样系统的改造,用双通道多维色谱,通过阀的切换,一次进样测定了裂解气的组成。该方法具有分析速成度快、重复性好、准确度高的特点,有较大的实用价值。

The system of flow control and injecting sample was modified. The composition of cracked gas determined by in-jecting sample once using gas chromatograph with twosignal channels and multi - column,via valve switching, the operation con-ditions of chromatograph was determined by test. The responsibility of test result was confirmed by parallel and comparable test. The method has the of quick anlysis rate,good repeatability and grreat value of use in practice.
