Section 1: System Description
Function and Theory
The High Vacuum Sampler is an air-sampling device that uses a compressor to draw air
from a sampling source and convey that sample into sealable sample bags. When an
external 12 VDC power source connects to the unit, the compressor is capable of
producing a vacuum of up to 27 in-Hg. Typical applications include soil vapor points or
Soil Vapor Extraction (SVE) systems.
Figure 1-1 is an example of the High Vacuum Sampler. Each High Vacuum Sampler
comes with a standard DC power cord (Figure 1-2) to allow the unit to operate from a
12VDC battery or cigarette lighter. An optional 110VAC power cord with adapter (Figure 1-
2) is also available. 1-liter and 3-liter sample bags (Figures 1-3 and 1-4) are available from
Geotech which can be used to easily collect air samples. See Section 8 for part numbers
to these accessories.
