气相色谱法测定TVOC操作条件的选择(热解吸法)

On selection of operation conditions for TVOC tested by gas chromatography cthermal desorption method

介绍了通过改变热解吸时间、色谱柱温度和进样时间来控制室内空气中有害气体TVOC的测定条件,以达到最佳测定结果,结果证实可以取得稳定而满意的测定数据。

The paper introduces the control over the testing conditions of the hazardous gas TVOC,in indoor air by changing the thermal desorption time,the temperature of the chromatographic column,and the injection time to achieve the optimized results,and proves by the result that this can achieve the stable and satisfactory testing data.
