Event Description

Forced Peak (FP) Forces integration between the start and end times. A

resolved baseline is drawn from the amplitude of the

chromatogram at the start time and the amplitude of the

chromatogram at the end time. Any Inhibit Integrate

events that overlap with a Forced Peak event are

ignored. The peak apex is the highest point in the forced

peak time range.

Split Peak (SP) Splits one peak into two peaks. A line is drawn from the

chromatogram at the split point to the baseline to

separate the original and new peaks. A Split Peak event

can be used to split into two peaks a weak shoulder that

was not recognized as a separate peak by data handling.

If the Split Peak event falls on a baseline section of the

chromatogram, the event is ignored.

Horizontal Forward (HF),

Horizontal Backward

(HB), and Horizontal

Minimum (HM)

These events cause a baseline to be drawn horizontally

rather than the way it would have been drawn without the

event. It does not force a baseline to be drawn, it merely

changes the way it is drawn. For Horizontal Forward, the

baseline amplitude is at the amplitude of the first peak

start event, for Horizontal Backward, the baseline

amplitude is at the amplitude of the last peak end event,

and for Horizontal Minimum, the baseline amplitude is at

the lowest data point in the baseline time range.

Signal to Noise Ratio

(SN)

Used to set the sensitivity of peak detection. If a peak is

being processed at the programmed time, the event will

not occur until a baseline segment is detected. Time

programming Signal to Noise Ratio overrides the initial

value set in the Integration Parameters Window.

Tangent Percentage

(TP)

Sets the percentage of a mother peak's size below which

a given peak is considered a tangent peak. Used to

assign tangent peak status as a percentage of the

mother peak size. Can be used to force a peak to be

integrated as a tangent or as a fused peak. Time

programming Tangent Percentage overrides the initial

value set in the Integration Parameters Window.

Peak Reject (PR). Sets the minimum size peak to be identified. Used to

eliminate very small peaks from the report, to ensure that

insignificant peaks are not mistaken for peaks of interest.

Time programming Peak Reject overrides the initial value

set in the Integration Parameters Window.
