2.4.2. Sample supply
The sample supply line must be heat-traced and/or insulated to keep the gas above dew
point. Check your sample data for required temperature.
Sample inlet connection on the analyzer is identified with a tag-plate.
The sample connection on the analyzer is for 1/8”OD tubing. Tubing size to the process
may require a different tube size, this should be determined taking into account process
pressure, sample line length and acceptable lag time.
2.4.3. Calibration gasses
Calibration gas composition is depending on range and process gas. COSA INSTRUMENT
can advise suitable compositions.
For a single range analyzer, 2 calibration gasses (low and high value) are recommended.
For a dual range analyzer, 3 calibration gasses (low/medium and high value) are
mandatory.
