Influence of Humidity on Measurement of Benzene Concentration in Air and its Solution

论文研究湿度对空气中苯检测的影响及解决方法。采用热吹扫使样品管脱除水分的措施进行改进后,检测方法适用于相对湿度0~90%的采样条件,可使方法精密度达3.0%~6.8%,回收率达90.0%~109.0%,准确度大幅度提高。

This article studied the influence of humidity on benzene detection in indoor air and its solution.The method was made an improvement used the removal of moisture in the sample tube,the test method is suitable for the sampling condition at the relative humidity 0~90%,the precision of the method could be achieved 3.0%~6.8%,the recovery reached 90.0%~109.0%,and the accuracy is significantly improved.
