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 peaks in the MS-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 of the same spectral data means that changing Integration Table for one of them including the usage of local parameters (such as Peak - Start) results in the changes visible while the integration table is displayed for the second one as well.

Some Integration Table items, when added into the table, are common for all quantification signals, while 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-MS Extension integration operations Global Threshold, Local Threshold or Min. Height are displayed in the Integration Table and logged in audit trail visually without unit, whereas integration operation Min. Area is displayed in the Integration Table and logged in audit trail with time unit only - [.s]. This is typically caused by MS Detector not providing the units to Clarity (as the units are something like counts).
