GC-ECD大体积进样分析水和土壤中多氯联苯

A 20-30 times more sensitive method than traditional GC- ECD has been developed and validated for the determination of PCBs in soil and water. Methods of analysis were evaluated through determination of detection limits (down to sub ppb level), quanti?cation limits (down to few ppb), linearity and repeatability. Validation was completed by the determination of PCBs extraction recoveries obtained using Liquid/Liquid and ASE extraction. LV-SL has proven to be a reliable tool for trace analysis in environmental applications, being robust against “very dirty” samples like soil extracts. LV-SL is theeasiest large volume injection GC technique, since it doesnot require any special hardware or tedious tuning of operating parameters. Full automation is provided through the dedicated LV-SL Assistant software.
