Abstract
Disclosed is a tool-like cartridge for preserving a soil sample which may be contaminated with a volatile organic compound (VOC). The cartridge includes a barrel and a plug in the barrel for sealing the barrel proximal end during and after sampling and for later expelling the soil sample from such barrel. A threaded portion is on the barrel for attaching a handle and such portion has an opening through it. From the moment of sample extraction until later sample expulsion for analysis, the plug and its resilient seal member substantially prevent vaporized VOC from escaping from the cartridge. A new method for obtaining a soil sample for analysis is also disclosed.
