总烃柱应用之安捷伦7890B
总烃柱应用之安捷伦7890B 详细信息：

浩瀚色谱（山东）应用技术开发有限公司用气相色谱法对《环境监测分析方法》（第二版）中总烃测定（试行）方法进行了验证，验证结果表明，不同型号的色谱仪对以氮气为底气的甲烷标气在０．１４～７．６７ｍｇ／ｍ３的范围内峰高与浓度的响应值呈线性；用１．４２ｍｇ／ｍ３，３．５５ｋｇ／ｍ３的标样，得出精密度分别为０．０２２、０．０２４；相对误差分别为１．５０％、－２．００％；环境空气样品加标回收率为９２．３０％～１０３．００％。根据验证结果编制了国家标准分析方法。

Total hydrocarbon column application Agilent 7890B

Details of Agilent 7890B for total hydrocarbon column application:



Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. has verified the total hydrocarbon determination (trial) method in Environmental Monitoring and Analysis Methods (second edition) with gas chromatography. The verification results show that the response values of different models of chromatographs to the peak height and concentration of methane standard gas with nitrogen as the base gas are linear within the range of 0.14-7.67mg/m3; The precision of 1.42mg/m3 and 3.55kg/m3 standard samples are 0.022 and 0.024 respectively; The relative errors are 1.50% and - 2.00% respectively; The recovery rate of ambient air sample is 92.30%~103.00%. According to the validation results, the national standard analysis method was prepared.
