摘要
甲醛、TVOC快速检测具有便捷、直观、简易、实时等特点,得到了广泛的应用。通过与《民用建筑工程室内环境污染控制规范》(GB 50325-2010)(2013版)中酚试剂分光光度法(甲醛)和气相色谱法(TVOC)之间的对比,分析两种方法差异性的显著意义。结果表明甲醛测定仪与酚试剂分光光度法之间t检验和r值检验显示差异无显著意义,具有可比性。由于室内空气组成和所占比例无法准确确定,导致TVOC测定仪与气相色谱法的测试数据之间不具有可比性。
The rapid detection of Formaldehyde and TVOC has much feature such as convenient, intuitive, simple, real-time and so on, it has been widely used. By comparison with the MBTH spectrophotometry （formaldehyde） and gas chromatography （TVOC） of ＂Code for Indoor Environmental Pollution Control of Civil Building Engineering＂ （GB 50325-2010） （2013）,this paper analyzed the significant of the differences between the two methods. The results showed that the differences has no significance by testing t and r between MBTH speetrophotometry （formaldehyde） and gas chromatography （TVOC）, which was comparable. Due to the composition and Proportion of the Indoor air could not be determined accurately, it is not comparable between the test data of the TVOC detector and gas chromatography
