    浩瀚色谱(山东)应用技术开发有限公司比较工作场所空气中氯乙烯采用FID与ECD气相色谱测定方法的技术参数。方法:氯乙烯分别采用直接进样或用活性炭管采集,热解吸进样,经DNP色谱柱分离,分别采用FID、ECD进行检测,比较技术指标。结果:FID测定氯乙烯在4.9×10~(-4)~2.0μg/ml范围内线性关系良好,r=0.9996,检出限为4.9×10~(-4)μg/ml;ECD测定氯乙烯在4.4×10~(-5)~2.0μg/ml范围内线性关系良好,r=0.9998,检出限为4.4×1O~(-5)μg/ml。结论:采用ECD气相色谱测定空气中的氯乙烯优于FID,且对于含量较低需直接进样的氯乙烯测定更具优势。

    Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. compared the technical parameters of the FID and ECD gas chromatography methods for the determination of vinyl chloride in the air of the workplace. Methods: Vinyl chloride was directly injected or collected by activated carbon tube, pyrolysed and aspirated, separated by DNP column, detected by FID and ECD respectively, and the technical indexes were compared. Results: FID determination of vinyl chloride in 4.9 × 10~(-4)~2.0 μ The linear relationship within the range of g/ml is good, r=0.9996, and the detection limit is 4.9 × 10~(-4) μ g/ml; ECD determination of vinyl chloride in 4.4 × 10~(-5)~2.0 μ The linear relationship within the range of g/ml is good, r=0.9998, and the detection limit is 4.4 × 1O~(-5) μ g/ml。 Conclusion: ECD gas chromatography is superior to FID in the determination of vinyl chloride in the air, and it is more advantageous for the determination of vinyl chloride with low content that requires direct injection.
