As default, the start and end base points of the baselines are calcu-

lated automatically. They can be set to fixed voltage values if de-

sired. The baseline scope Front end or Rear end for linear baselines

should be selected for asymmetric or double peaks.

Evaluation quantity calculation

The peak evaluation quantity is identical for all peaks of a determi-

nation and must be set on the Substances tab of the EDIT WOR-

window (see Working method speci-

fications window, section 5.2). With the aid of the calculated base-

lines, the set evaluation quantity

Height, Area, Derivative or Coulo-

metric

is determined for each substance peak and displayed as a

result.
