The Xitech 1060H vacuum bag sampler can be used for collecting low ambient air and high vacuum VOC vapors. The pump removes air from the box, creating a vacuum. Negative pressure inside the box causes air to flow into a 1 or 2 liter bag.
The sample flows directly into the bag's inlet without passing through the vacuum pump, as the vacuum pump can introduce contaminants to the sample.
The Xitech 1060H can be used for collecting air samples from the negative side of a Vapro Extraction System. It can also be used to collect hard to get soil gas samples.
