【摘要】 基于氢火焰离子化检测器（FID）色谱法研制了一种甲烷/非甲烷总烃分析仪。采用双色谱柱，根据色谱分离原理，对样气中甲烷和总烃进行延时检测，实时监测样品中的甲烷和非甲烷总烃的浓度。通过标准气体混合物测试，得出仪器具有高准确度和高稳定性的测量结果。更多还原

【Abstract】 This study developed a methane/non methane total hydrocarbon analyzer based on the hydrogen flame ionization detector(FID) chromatography method. According to the Separation principle of chromatography, the methane and total hydrocarbon in the sample gas are detected in a delayed manner by using double chromatographic columns, and the concentration of methane and non methane total hydrocarbon in the sample is monitored in real time.Through standard gas mixture testing, the instrument has high accuracy and stability measurement results.更多还原
