| Abstract: | A method for on-site analysis the 54 volatile organic compounds ( VOCs) in the atmosphere was established by u-sing portable gas chromatography -mass spectrometry.The linear,recovery (56.3%~141.1%),precision (3.80%~22. 69%) and detection limit of each compound were detected ,and this method was carried out to detect the actual samples .Re-sults shows that the method has good precision and accuracy ,highly sensitivity,digestion thoroughly,simplicity,which is appli-cable to the on-site analysis of the 54VOCs in the atmosphere. |
