Several analyzer types are of sufficiently sound design and manufacture to meet the industry-standard requirements for general purpose gas detection. Many of these also maintain this accuracy under normal conditions for a reasonable period of time following calibration.
It is much less common, however, for the accuracy to be maintained for the following, that are routinely found in industrial processes:
- varying mixtures of solvents
- under the difficult conditions of temperature
- continuously high solvent concentrations
- presence of contaminating substances & particulates
Choosing an analyzer that withstands these condiitons is of upmost importance to the success of your process.
