Baseline Allocation; Default Baseline Construction - Agilent Technologies 8453 Operator's Manual

Baseline Allocation

After any peak cluster is complete, and the baseline is found, the integrator
requests the baseline allocation algorithm to allocate the baseline using a
pegs-and-thread technique. It uses trapezoidal area and proportional height
corrections to normalize and maintain the lowest possible baseline. Inputs to
the baseline allocation algorithm also include parameters from the method
and data files that identify the detector and the application, which the
integrator uses to optimize its calculations.

Default Baseline Construction

In the simplest case, the integrator constructs the baseline as a series of
straight line segments between:
• the start of baseline,
• the tick marks,
• the end of peak
