建立了吹扫捕集-气相色谱/质谱法测定地表水环境质量标准所要求必须监测的27种挥发性有机物。采用全扫描和选择离子扫描方式,内标法进行测定,提高了定性、定量分析的准确性。各目标物方法检出限为0.04～2.8μg/L,加标回收率为82.7%～108%,RSD为1.42%～8.68%。
建立瞭吹掃捕集-氣相色譜/質譜法測定地錶水環境質量標準所要求必鬚鑑測的27種揮髮性有機物。採用全掃描和選擇離子掃描方式,內標法進行測定,提高瞭定性、定量分析的準確性。各目標物方法檢齣限為0.04～2.8μg/L,加標迴收率為82.7%～108%,RSD為1.42%～8.68%。
건립료취소포집-기상색보/질보법측정지표수배경질량표준소요구필수감측적27충휘발성유궤물。채용전소묘화선택리자소묘방식,내표법진행측정,제고료정성、정량분석적준학성。각목표물방법검출한위0.04～2.8μg/L,가표회수솔위82.7%～108%,RSD위1.42%～8.68%。
A method is established for determination of 27 volatile organic compounds in water by purge and trap-gas chromatography/mass spectrometry.Full scan mode,selective ion mode and the internal standard method are used to improve the accuracy of the qualitative and quantitative analysis.The detection limit is in a range of 0.04μg/L~2.8μg/L,the recoveries are between 82.7%~108% and the RSD lies between 1.42%~8.68%.
