不同标准物质对气相色谱仪FID检测限的影响

Influence of Different Reference Materials on Detection Limit of Gas Chromatograph FID Detector

针对空气质量和酒类检测用气相色谱仪的使用特点,分别选取四种标准物质对仪器的检测限进行检定,通过分析对比,研究不同标准物质对仪器检测限的影响。结果证明使用不同标准物质,FID检测限结果差距很大,不能作为仪器合格判定的依据。

According to the characteristics of gas chromatograph for air quality detection and alcohol detection,four kinds of reference materials were selected to verify the detection limit of the instrument,through analysis and comparison,the influence of different reference materials on the detection limit of the instrument was studied. The results show that different reference materials have great influence on the detection limit of the instrument,so they cannot be used as the basis for determining whether the instrument is qualified.
