HH-HCL 环境空气中氯气测定填充柱

名称：填充柱
材质：聚四氟乙烯

型号：HH-HCL

规格：2m*1/8，60-80目

编号：20220709011

使用温度：200°C

HJ/T 30-1999《固定污染源排气中氯气的测定甲基橙分光光度法》适用于固定污染源有组织排放和无组织排放的氯气测定。然而在测定实际样品中发现,当测定环境空气及无组织的氯气时标准方法的测定下限偏高,会造成分析环境空气中的氯气样品一检出就超标的现象。

浩瀚色谱（山东）应用技术开发有限公司采用气相色谱法测定,所得标准曲线线性关系较好,准确度和精密度均高,当采样体积为30L时,检出限能达到0.006mg/m3,定量测定下限为0.0198 mg/m3。

HJ/T 30-1999 "Determination of Chlorine in Exhaust from Stationary Pollution Sources Methyl Orange Spectrophotometry" is suitable for the determination of chlorine gas in the organized and unorganized emissions of stationary pollution sources. However, in the measurement of actual samples, it is found that the lower limit of the standard method is too high when measuring ambient air and unorganized chlorine, which will cause the phenomenon that the chlorine samples in the ambient air will exceed the standard as soon as they are detected.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses gas chromatography to determine the obtained standard curve with good linearity, high accuracy and precision. When the sampling volume is 30L, the detection limit can reach 0.006mg/m3, quantitative The lower limit of determination is 0.0198 mg/m3.
