The following table defines the parameters used in the ICIS algorithm for peak detection.

Parameter

Subparameter

Description

Baseline Window

N/A

Specifies the number of scans that the peak detection algorithm uses to determine the peak’s minimum baseline. A greater number of scans indicates a wider scan range, which results in a lower baseline.

Range: 1–500; default: 40.

Area Noise Factor

N/A

Specifies the noise level multiplier that the peak detection algorithm uses to determine the peak edge after the location of the possible peak.

Range: 1–500; default: 5.

Peak Noise Factor

N/A

Specifies the noise level multiplier that the peak detection algorithm uses to determine the signal threshold of a potential peak.

Range: 1–1,000; default: 10.

Constrain Peak Width

Checkbox

Limits the peak width of a component during the peak integration of a chromatogram.

Peak Height (%)

N/A

Specifies how much above the baseline (as a percentage) the total peak height of a signal must be before integration turns on or turns off.

Range: 0.00–100.0; default: 5.

Tailing Factor

N/A

Specifies a factor that controls how the algorithm integrates the tail of a peak. This factor is the maximum ratio of the trailing edge to the leading edge of a constrained peak.

Range: 0.50–9.0; default: 1.
