MS Integration
The Integration tab shows Integration Table for detectors' signals, and is the same as in standard Clarity. This table is for integration of standard signals coming from detectors, serving as Result Table Signal.
The MS Integration tab shows Integration Table for compound's quantification signals, the most important signals for evaluating the result in the MS Extension. The Integration Table is unique for each quantification signal. When more compounds use the same quantification signal, such signal is shared among them. For example, having compound A and compound B quantified on the same m/z value means, that changing Integration Table for one of them results in the same changes for the second one.
Therefore, some Integration Table items are common for all signals, but some are specific for each particular quantification signal, and some are even missing on the quantification signal. The items common to all signals, those specific for each quantification signal and items missing are listed in following table:
Integration Table items
Table items common to all signals | Table items specific for each quantification signal | Table items not available on quantification signal |
---|---|---|
Global Peak Width | Local Peak Width | Detect Negative |
Global Threshold | Local Threshold | Baseline Clamp Negative |
Global Filter - Bunching | Baseline Allow Crossing | Baseline Cut Negative |
Integration Interval | Baseline Spike Removal | Baseline Reject Negative |
Minimal Area | Baseline Lock | Peak Flow Marker |
Minimal Height | Baseline Valley | Peak Force Peak Name |
Minimal Half Width | Baseline Together | Group Add Group |
Valley To Valley Slope | Baseline Forward Horizontal | Group Remove Group |
Tangent Area Ratio | Baseline Backward Horizontal | |
Tangent Slope Ratio | Baseline Front Tangent | |
Detector Delay | Baseline Tail Tangent | |
Filter - FFT | Peak Start | |
Filter - Savitzky-Golay | Peak End | |
Filter - Spike | Peak Both | |
Filter - Moving Average | Peak Add Positive | |
Noise Evaluation | Peak Add Negative | |
ASTM Noise Evaluation | Peak Solvent | |
6-Sigma Noise Evaluation | ||
Drift Evaluation |
This information is important in understanding which parameters can be changed just for one quantification signal and which will influence all quantification signals.
Note:
In MS Extension integration operations Global Threshold, Local Threshold or Min. Height are displayed in the Integration Table and logged in audit trail without unit, whereas integration operation Min. Area is displayed in the Integration Table and logged in audit trail with time unit only - [.s].
