Calibration compares detector response against a gas with known composition. The analyser uses that comparison to update the relationship between signal and concentration.
Why calibration is necessary
Even when the method and hardware are correct, detector response can change over time. Calibration keeps the measurement anchored to a known reference.
What makes calibration believable
Believable calibration depends on stable sample handling, correct calibration gas data, repeatable injection, and sensible response factor behaviour.
What calibration cannot fix
Calibration cannot fully rescue a contaminated sample path, poor valve timing, or unstable detector operation. It may temporarily hide the real issue rather than solve it.
How to think about calibration
Calibration should be treated as both a measurement task and a health check. A good calibration confirms more than numbers; it confirms system behaviour.
