In the sampling position, a movable piston is attached to the top of the sampling tube, and a fixed piston rests on the soil to be sampled. The sampler is activated by pumping fluids or gas through the pressure cylinder, which drives the upper piston and sampling tube down over the lower piston into the soil a fixed distance.
12.2 General Guidance for Sample Preparation . Some general considerations during sample preparation are to minimize sample losses and to prevent contamination. Possible mechanisms for sample loss during preparation steps are discussed in Section 12.2.1, and the contamination of samples from sources in the laboratory is discussed in Section 12.2.2.
the sample tube out of the soil in order to avoid losses.
