ABSTRACT:
The present invention is a self-contained apparatus for sampling fluids. The apparatus permits a fixed volume of conditioned sample to be delivered directly or through a sample valve to a means of detecting the sample. The amount of sample that gets into the atmosphere is negligible since all or all but a minuscule amount of the sample is returned to the vessel. Sample handling and maintenance are minimized, and calibration of analytical instrumentation is simplified.
