Integration

Menu for adjustment of integration parameters. All commands can also be invoked using icons from the Integration toolbar.

All integration parameters are executed as a part of the Integration Table (for more details see also chapter Integration). All of these parameters are interval parameters, which means that it is possible to define the time frame of their validity and in particular to select various values for various parts of the chromatogram.

All interval operation follows the rule that with Time B = 0 operation will be applied from Time A to the end of the chromatogram. With both Time A and Time B set to 0, operation is applied over the whole chromatogram.

Integration commands in Baseline bar

Local Peak Width Defines minimum width of peak.
Local Threshold Describes the threshold of noise.
Local Baseline Slope Defines the position of automatically found peak starts and peak ends. The command is only available if Wave Integration Algorithm is used.
Integration Interval Sets the interval for the integration algorithm.
Detect Negative Detects negative peaks.
Minimal Area Sets the minimum peak area.
Minimal Height Sets the minimum peak height.
Minimal Half Width Sets the minimum peak width in half-height of the peak.
Detector Delay Shifts the signal on the time axis.
FFT Filter Applies/suspends the FFT Filter (Fast Fourier Transformation) for noise reduction.
Savitzky-Golay Filter Applies/suspends the Savitzky-Golay Filter for noise reduction.
Moving Average Filter Applies/suspends the Moving Average Filter for noise reduction.
Spike Filter Applies a filter that removes spikes to the selected region of the chromatogram. Only available in Clarity version 4.0 or higher.
