The calibration curve of 25 VOCs were liner in the range of 0.5~20 μg/L with correlation coefficients more than 0.990. The limits of detection and quantitation were in the range of 0.10~0.51 and 0.40~2.04 μg/L. Through the laboratory test comparison, the method was proved to achieve the same level of laboratory monitoring instruments. %R %U http://www.hjjkyyj.com/hjjkyyj/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
