汽车用R134a制冷剂测定填充柱 详细信息：

名称：R134a填充柱
型号：2m*3mm,60-80目


车维修用空调制冷剂,被广泛应用于汽车维修中,自2002年起,国家规定新下线汽车必须使用R134a作为制冷剂。由于生产成本的原因,市面上仍大量存在含有R12,R22等成分的制冷剂冒充R134a制冷剂在销售和使用,长期使用这种制冷剂严重影响汽车空调系统正常运转并带来严重的环境污染。长期以来,没有针对汽车空调制冷剂成分的检测标准,给质量监控带来了一定的难度。

浩瀚色谱（山东）应用技术开发有限公司建立了汽车空调制冷剂R134a快速气相色谱定性和定量分析方法。采用R134a色谱柱,以热导池检测器检测,以面积归一化法定量。结果表明,该方法操作简单,实用性强,重复性好,可以用于快速分析汽车空调制冷剂R134a。

Model: 2m*3mm, 60-80 mesh


Air conditioning refrigerants for vehicle maintenance are widely used in vehicle maintenance. Since 2002, the state has stipulated that new off-line vehicles must use R134a as a refrigerant. Due to the production cost, there are still a large number of refrigerants containing R12, R22 and other components in the market as R134a refrigerants that are sold and used. Long-term use of this refrigerant will seriously affect the normal operation of automobile air conditioning systems and cause serious environmental pollution. For a long time, there is no detection standard for the composition of refrigerants in automobile air-conditioning, which brings certain difficulties to quality monitoring.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has established a fast and efficient gas chromatographic qualitative and quantitative analysis method for automotive air-conditioning refrigerant R134a. Using R134a chromatographic column, detecting with thermal conductivity cell detector, and quantifying with area normalization method. The results show that the method is simple to operate, has strong practicability and good repeatability, and it can be used to quickly analyze the refrigerant R134a of automobile air-conditioning.
