吹扫捕集-气相色谱-质谱法测定海岸带表层沉积物中挥发性有机物
GC-MS Determination of Volatile Organic Compounds in the Surface Sediments of Coastal Zone with Purge and Trap Concentrator
摘 要
应用吹扫捕集-气相色谱-质谱法测定海岸带表层沉积物中28种挥发性有机物的含量。选定在40 ℃条件下吹扫捕集11 min,取样品于吹扫瓶中,利用PTA 3000吹扫捕集仪直接进样,经J&W DB5-MS毛细管色谱柱分离,电子轰击电离全扫描检测,内标法进行定量测定。28种挥发性有机物的方法检出限在0.16~0.38 μg·kg-1之间,样品加标回收率在70.7%~115.5%之间,相对标准偏差(n=7)在1.7%~7.8%之间。

Abstract
PTA 3000 purge and trap concentrator was used in GC-MS determination of 28 volatile organic compounds (VOC′s) in surface sediments of coastal zone. Temperature and time for purging and trapping were set at 40 ℃ and 11 min respectively. The sample was transferred from the purge and trap bottle and introduced into the instrument for GC-MS analysis. The VOC′s were separated on J&W DB5-MS capillary column and detected by the modes of electron ionization and full-scanning. Internal standard was adopted in the determination. Values of detection limits of the method found were in the range of 0.16-0.38 μg·kg-1. Test for recovery were made by addition of standard VOC′s to sample matrixes; values of recovery obtained were in the range of 70.7%-115.5%. Values of RSD′s (n=7) found for the VOC′s were in the range of 1.7%-7.8%.
