摘要: 空气净化器标准GB/T 18801-2015中甲醛CADR在30立方米测试舱的测试范围是20~400m3/h,现在市面上已经有很大一部分空气净化器甲醛CADR大于400m3/h,使用酚试剂分光光度法测试时必须采用4口交叉采样方式进行,该四口交叉采样方法繁琐,对实验人员专业水平要求高;而在线质谱检测方法可以避免繁琐的采样方法,相同时间内可以采集到的数据点多,测量范围更广,结果更加真实可靠。本文分别使用酚试剂分光光度法、在线质谱法测试甲醛CADR大于400m3/h的空气净化器,对测试结果数据进行分析,比较两种方法的差异。

Abstract: In the air purifier standard GB/T 18801-2015, the test range of formaldehyde CADR in the 30 cubic meter test chamber is 20~400m3/h. Now in the market there is a large part of the air purifier whose test range of formaldehyde CADR is greater than 400m3/h. Also, the photometric spectroscopy using phenol reagent must be carried out by 4-port cross-sampling method, which is cumbersome and requires high professional level for the experimenter. The online mass spectrometry detection method can avoid the cumbersome sampling method. Moveover, such method can collect more data points at the same time. The measurement range is wider, and the results are more realistic and reliable. In this paper, phenol reagent spectrophotometry and on-line mass spectrometry, respectively, were used to test the air purifier with formaldehyde CADR greater than 400m3/h. The test results were analyzed to compare the differences between the two methods..
