【摘要】 通过考察甲醛快速测定仪分析方法的线性范围、灵敏度、准确度、精密度及方法扩展不确定度等技术指标,研究环境因素如空气中干扰物、温度、湿度、风速等的影响,比较甲醛快速测定仪与国家标准方法在测试甲醛标准气体或室内空气测试结果的差异。结果证实甲醛快速测定仪分析方法的特性优异、测试结果受环境因素影响小与国家标准方法测试结果相关性好,适合测试室内空气中的甲醛气体。更多还原

【Abstract】 Some method characteristics of formaldehyde detector such as linearity,sensitivity,accuracy,precision and extended uncertainty were investigated,environmental factors such as interferential substances,temperature,humidity,wind speed were also studied,and difference between results from formaldehyde detector and those from national standard method was analyzed too.Those results showed that analysis characteristics of formaldehyde detector is excellent,environmental factors seldom affect on the results from this method,and these results have a good correlativity to those of national standard method.更多还原
