| General Information |
|
The BioTector® vacuum sampling system is designed to bring water over a distance of 40 meters with a maximum lift of 6 meters, and to present the sample to the BioTector® TOC analyser or alternative water analyser at ambient pressure.
Functions
The operation of the sampling system is controlled from the analyser and operates as follows:
1. The vacuum sampler pump generates a vacuum in the sample container which draws the sample up into the sample container.
2. A built-in conductivity probe confirms that the sample has filled the container. The vacuum pump is stopped, a pinch valve closes to seal the sample in the container and vacuum valves open to restore the pressure in the sample container to ambient. If the sample does not make contact with the conductivity probe within a pre-set time, a fault condition is triggered.
3. The analyser takes its sample from the container. If necessary, a short sedimentation period (to allow sand and hard particles to settle) may be programmed before the analyser takes its sample.
