目的：了解便携式甲醛测定仪使用方法及在现场检测中的应用，掌握气体的体积浓度与质量浓度的数据换算。方法使用理研FP-30型甲醛测定仪对空气中的甲醛含量进行检测。结果对14个办公场所进行了监测，甲醛最高浓度大于1.23mg/m3，42.9%(6/14)办公场所的超过国家限值0.08 mg/m3的标准。相对偏见差为17.5%，在平行双样分析相对偏差允许值范围内。结论理研FP-30型甲醛测定仪体积小便于携带、操作简单、检测过程时间短，结果相对稳定，适用于空气中甲醛的现场检测工作。%Objective To investigate the use of portable formaldehyde analyzer and its application in the field of detection, volume concentration and quality control of gas concentration data conversion. Methods Uses RIKEN FP-30 Formaldehyde analyzer formaldehyde content in the air were detected. Results The 14 premises were monitored, the highest formaldehyde concentration greater than 1.23 mg/ m3, exceeding the national limit of 42.9% (6/14) premises 0.08 mg / m3 standards. Dif erence of 17.5% relative bias, sample analysis in a dual paral el relative deviation al owable value. Smal .Conclusion RIKEN FP-30 Formaldehyde detector volume easy to carry, easy to operate, the detection process time is short, the results are relatively stable, on-site testing work applies to formaldehyde in the air.
