- HAOHAN氮气中氯气含量的检测填充柱H-HCL2m*1/8
详细信息
品牌:HAOHAN 型号:2m*1/8 加工定制:是 测量范围:ppm 测量对象:非甲烷总烃 控温范围:200 ℃ 尺寸:60000 mm 重量:0.02 Kg 气体中氯气含量的检测:硫化氢 磷化氢:氯化氢 石墨化碳黑:零级空气发生器 氧化铝:* 环氧乙烷:消毒剂 氯气具有强烈刺激性气味的黄绿色有毒气体,它主要通过呼吸道侵入人体并溶解在黏膜所含的水分里,对上呼吸道、肺、皮肤等造成严重损害。
目前测定气体中氯气含量,常规方法是用甲基橙分光光度法、碘量法等。甲基橙分光光度法是通过氯气将溴化钾-甲基橙的酸性溶液中的溴化钾氧化成溴,通过溴对甲基橙显色,采用分光光度法测试;碘量法是通过氯气氧化碘化物生成碘,采用硫代硫酸钠标准溶液滴定法测试。
这两种方法操作步骤冗长费时,测定过程中需用到多种化学试剂,测定结果易受到环境温度、反应时间等因素的干扰,导致测试结果重复性差、准确度低。
浩瀚色谱(山东)应用技术开发有限公司研发气相色谱法,以连续检测色谱分离的方法,选择性好、准确度高,可以避免环境温度、反应时间等因素对检测结果的干扰。

Chlorine is a yellow-green toxic gas with a strong irritating odor. It mainly invades the human body through the respiratory tract and dissolves in the moisture contained in the mucous membranes, causing serious damage to the upper respiratory tract, lungs, and skin.
At present, the conventional methods for the determination of chlorine content in gas are methyl orange spectrophotometry, iodometric method, etc. Methyl orange spectrophotometry is to oxidize potassium bromide in an acidic solution of potassium bromide-methyl orange to bromine by chlorine gas, and the color of methyl orange is developed by bromine, which is tested by spectrophotometry; iodometric method is determined by chlorine gas. Oxidation of iodide produces iodine, which is tested by titration with a standard solution of sodium thiosulfate.
The operation steps of these two methods are lengthy and time-consuming, and various chemical reagents are used in the measurement process. The measurement results are easily interfered by factors such as ambient temperature and reaction time, resulting in poor repeatability and low accuracy of test results.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. develops gas chromatography, a method for continuous detection of chromatographic separation, with good selectivity and high accuracy, which can avoid the interference of environmental temperature, reaction time and other factors on the detection results.
