现场快速测定甲醛的监测分析方法

On- the- Spot Fast Monitoring and Analysis on Formaldehyde Measurement

文章介绍了GDYQ-201M室内空气现场甲醛·氨测定仪法测定空气中甲醛的方法，并与空气质量中甲醛的测定乙酰丙酮分光光度法（GB／T15516—1995）比较。对准确度，精密度等都进行了详细地实验，得出满意的结果。结果表明，在0．00—5．00mg／m^3范围内，用GDYQ-201M室内空气现场甲醛·氨测定仪法测定甲醛完全可以满足室内空气样品中甲醛的测定。

This article introduces a method to measure the quantity of formaldehyde existed in indoor air by using GDYQ- 201M indoor air on -the -spot formaldehyde -ammonia meter, and also compares another method of formaldehyde measurement by diacetylmethane spectrophotometry（ GB/T15516 -1995 ）. The detailed testing about accuracy and precision shows that in the range of 0. 00 - 5. 00mg/m^3 , to use GDYQ -201M indoor air on - the - spot formaldehyde - ammonia meter to measure the quantity of formaldehyde can totally meet the need of formaldehyde measurement of indoor air samples.
