"Fraction Detection Parameters" Category

The Fraction Detection Parameter category includes different variables that indicate the peak detection setting for the present fraction. This category can be opened only via the Fraction category.

 Note: 

In the Printer Layout, the Fraction Detection Parameter category is available only for report tables.

The Fraction Detection Parameter category includes the following variables:

 

Variable

Formula

Description

Detection Channel

frac.channel.channel

Channel for peak detection

Channel Name

frac.channel.name

Name of the channel used for peak detection.

Peak Start Slope

frac.channel.start_slope

The slope must exceed the Peak Start Slope value for the peak start to be recognized.

Peak Start Curve

frac.channel.start_curve

Curve in [Signal]/s^2 that must be exceeded for a shoulder to be recognized after the peak start.

Peak Start True Time

frac.channel.start_truetime

The time must be fulfilled for the different conditions for a peak start to be recognized.

Peak Start Threshold

frac.channel.start_threshold

The signal threshold value must exceed the Peak Start Threshold value for the peak start to be recognized.

Peak Max Slope

frac.channel.max_slope

The slope value must be below the Peak Max Slope value for the peak maximum to be recognized.

Peak Max True Time

frac.channel.max_truetime

The time must be fulfilled for the different conditions for a peak maximum to be recognized.

Peak End Slope

frac.channel.end_slope

The slope value must be below the Peak End Slope value for the peak end to be recognized.

Peak End Threshold

frac.channel.end_threshold

The signal threshold value must be below the Peak End Threshold value for the peak end to be recognized.

Peak End Curve

frac.channel.end_curve

Curve in [Signal]/s^2 that must be exceeded for a shoulder to be recognized after the peak maximum.

Peak End True Time

frac.channel.end_truetime

The time must be fulfilled for the different conditions for a peak end to be recognized.

Threshold No Peak End

frac.channel.threshold_no_peak_end

The signal threshold value must be below the Threshold No Peak End value for the peak end to be recognized.

Baseline Drift

frac.channel.baseline_drift

Start value for the baseline drift. This value is used to correct the signal value.

Baseline Offset

frac.channel.baseline_offset

Start value for the baseline offset. This value is used to correct the signal value.

Threshold Do Not Resolve

frac.channel.thrs_no_resolve

Threshold value for the slope in [Signal]/s above which peak detection via the PeakEndSlope parameter was disabled.

Deriv. Step

frac.channel.deriv_step

Time for which the signal values were evaluated to determine the signal slope and the curve.
