REST Laboratory Equipment
Samples for training and accreditation were produced in a laboratory by placing the target odour inside a sample tank and drawing a controlled air sample through a filter.
The air was drawn down stream by means of the laboratory pump. This pump was based on our patented RAS 1 K9 cargo pump covered on our Patent No; GB2455084.
To avoid cross contamination each training odour were kept with each individual tank and each individual filter holder. This procedure included a control sample as a blank.
With this system you only need one vacuum pump downstream of the filter and sample tank. There is no cross contamination with the pump and sample.
Individual companies could set up their own mini laboratory to produce their own training samples and control accreditation samples came directly from the DSTL.
