WebThe essential rules for manual reintegration are (a) the person doing the integration must be identified, (b) the date and time must be noted, (c) a copy of the original (raw) data must be preserved, and (d) a reason for the change must be recorded. WebIntegration of chromatographic peaks (determination of height, area, and retention time) is the first and most important step in the data analysis of HPLC and GC methods. This information is used for all subsequent calculations, including construction of calibration curves and calculation of unknown concentrations. take a stand song

Baseline upsets, coelution and peak shape variation can sometimes complicate automatic integration and analyst intervention through the process of manual integration may be required twisted copper tubingWebIn this HPLC Solutions series on integration, we’ll look at how peaks are integrated and what can go wrong. This instalment centres on the integration process itself. Conceptually, the measurement of a peak’s height or area is pretty simple. For peak height, just measure the vertical distance from the baseline to the highest point. take a stand pattern
