Integration

Seen on chromatograms, method statements.

Definition

The process of defining where each peak starts and ends on the baseline and calculating the area between. Integration parameters are part of the method, and applying them inconsistently across a run is one of the failures data review exists to catch.

Related terms

Area purity
The area of the principal peak expressed as a percentage of the total integrated detected response in the run, under stated method conditions and at a stated detection wavelength.
Baseline
The detector response with no analyte eluting.
