摘　　要：INNOVA-1412i红外光声气体监测仪可快速、实时监测室内空气中甲醛浓度。为验证其测试结果的可靠性,采用红外光声气体监测仪与酚试剂法(国标仲裁法)对空气中甲醛浓度进行对比检测。两种方法检测结果的统计学检验表明,两种方法的检测结果不存在显著性差异,相关性分析表明两种方法测量结果线性关系好、相关性显著,即两种方法可等同使用。但红外光声谱法具有操作简单、快速等优势,值得推广应用。Rapid test and real-time monitoring of indoor formaldehyde could be realized by an infrared photoacoustic gas monitor(INNOVA-1412i).A comparative study was carried out between infrared photoacoustic spectroscopy and phenol reagent spectrophotometry(GB/T 18204.2—2014)to verify its reliability.According to the statistical tests,there was no significant difference between the two test methods.And the linear correlation between the two method results was significant.Thus infrared photoacoustic spectroscopy was worthy of being promoted due to its simple operation,rapid test,etc.
