This application note describes an onsite solution for detecting 13 volatile aromatic compounds in soil with the transportable Agilent 5975T LTM GC/MSD. The solution uses a manual SPME method for sample pretreatment. The transportability of the Agilent 5975T LTM GC/MSD makes onsite detection possible while saving soil sam- pling time and storage. The testing results proved that this solution is practical and effective for detection of volatile organic compounds in soil in the field. The lowest detection amount of this method is 1.0 µg/kg in soil.
This document details a method for detecting 13 volatile aromatic compounds in soil samples. The technique utilizes solid phase microextraction (SPME) for sample pretreatment, which requires no solvents or power, making it suitable for field applications.
The analysis is performed using the transportable Agilent 5975T LTM GC/MSD system with manual injection mode and an HP-5ms UI LTM column. The method achieves a lowest detection amount of 1.0 pg/kg in soil.
The lowest detection amount of this method is 1.0 pg/kg in soil.
The linear calibration curves were generated by the calibration standards at a concentration range of 5.0—50 pg/kg.
