Abstract
A process for testing an air source by providing a bag to collect a sample of gas. Connecting the filled bag to a collector assembly that has a fraction of the interior volume of the bag. Forcing the air sample from the bag over a media dish inside the collector assembly. Removing the media for further analysis. Both the bag and the collector assembly have one way exhaust valves to prevent over-pressure and allow a limited flow through of the sample.
Claims4
A process for testing a gas sample comprised of:
- providing a sampler assembly and a collector assembly;
- the sampler assembly is comprised of a bag configured with a side panel and a first interior;
- the first interior is configured with a first predetermined volume;
- affixed to a first aperture in the side panel is a first one-way valve configured to input a gas sample to the first interior;
- affixed to a second aperture in the side panel is a second one-way valve configured to exhaust the gas sample from the first interior;
- the second one-way valve is configured to permit an exhaust flow only above a predetermined first pressure;
- selecting a gas source comprised of a gas;
- connecting the gas source to the interior of the bag through the first one-way valve;
- delivering a portion of the gas from the gas source to the first interior of the bag;
- venting the gas from the first interior of the bag through the second one-way valve when the interior of the bag exceeds the first pressure;
- the collector assembly is comprised of a cover assembly, a base assembly and a dish assembly;
- the cover assembly and base assembly are configured to join together at an airtight seal with the dish assembly disposed therein;
- the collector assembly is configured to have a second interior between the cover assembly and the bottom surface of the dish assembly;
- the second interior is configured with a second predetermined volume;
- the second volume is less than thirty percent of the first volume;
- the dish assembly has a bottom surface covered in a media;
- affixed to a third aperture in the cover assembly is a nipple;
- affixed to a fourth aperture in the cover assembly is a third one-way valve configured to exhaust the gas sample from the second interior of the collector assembly;
- the third one-way valve is configured to permit an exhaust flow only above a predetermined first pressure;
- connecting the second one-way valve to the nipple;
- expelling the gas in the first interior through the second one way valve and the nipple into to the second interior thereby exposing the media to the gas;
- venting the gas from the second interior through the third one-way valve when the second interior exceeds the second pressure;
- removing the dish assembly from inside the collector assembly;
- providing the media in the dish assembly for analysis.
