Integration The Data Explorer software integrates chromatographic and
spectral peaks to calculate the peak area using one of two
methods to determine the peak baseline (Figure 3-25):
• Valley-to-baseline—Drops a vertical line from all valleys
to a horizontal baseline. The level of the horizontal
baseline is determined using the minimum peak valley
point (left or right) for each peak.
• Valley-to-valley—Forces a baseline to all valley points.
