The apparatus may include a vacuum source connected to the PID that produces a reduced pressure for drawing the sample through the PID.
The flow restrictor may provide variable resistance to set a desired clearance time through the PID and sensitivity of the PID.
A flow restrictor may be positioned between the sampler and PID.
The present invention relates to an apparatus for measuring a compound using a photo-ionization detector.
A PID is connected to the sampler to receive the sample and produce a signal corresponding to contents of the sample.
The Phot- Ionization Detector (PID) is a specialized sensor that is known as a broad-range sensor, as it is not specific to any one gas.
A controller is connected to the PID and receives and analyzes the signal to determine whether the container is suitable for storing water.
A photo-ionization detector or PID breaks molecules into positive and negative charged ions and measures the electrical charge of these ions using a detector to display the amount of gas or vapor that is present.
