How often must an analyzer be calibrated?

ETI analyzers are calibrated after installation using samples made from the materials used in the existing process. Laboratory analysis is performed on the samples and a comparison is done with the analyzer results. Analyzer results are then adjusted to match the laboratory analysis.

No two detectors are exactly alike. If a detector is replaced, the replacement will have slightly different physical characteristics, and the calibration must be checked by running the samples used at installation. A calibration adjustment will be performed if needed.

The analyzer's calibration covers a wide range of materials, but it is possible to introduce a material with enough differences to warrant recalibration. If a recalibration is needed, it will be performed using samples made from the new material.
