Abstract:
1. A sampling system comprising: a sample withdrawal system operative to withdraw a sample from a source at a sample withdrawal flow rate; a sample collector system operative to receive the sample; a sample delivery system operative to deliver the sample from the sample withdrawal system to the sample collector system at a sample delivery flow rate that is faster than the sample withdrawal flow rate; and wherein the sample withdrawal system comprises a sample intake port through which the sample is drawn from the source and an air intake port through which air is drawn, wherein the air intake port introduces air at a downstream end of the sample, and wherein the sample and air are delivered by the sample delivery system to the sample collector system at the sample delivery flow rate that is faster than the sample withdrawal flow rate, wherein the sample delivery system includes a pump that operates at a first speed to draw the sample from the source at the sample withdrawal flow rate, and that operates at a second speed to expedite delivery of the sample to the sample collector system at the sample delivery flow rate.
