Canned Calculation for SANTE Guideline 12682_2019 - C15 Available for SCIEX OS Software

For research use only. Not for use in diagnostic procedures.

Issue Description

SCIEX provides pre-assembled calculation packages ('Canned Calculations') for use with processing methods created in SCIEX OS software for several common application workflows. These calculation packages can be used with SCIEX OS software version 2.2 and higher (depending on the used software features) and contain the custom calculations and flagging rules needed to process data for a commonly-used application, such as the technical guidance for detecting pesticide residues in the European Union, SANTE 12682 2019.

This article provides information on the custom calculations required for processing data according to the guidance found in SANTE 12682 2019 - C15:
‘Bracketing calibration must be used unless the determination system has been shown to be free from significant drift, e.g. by monitoring the response of an internal standard. The calibration standards should be injected at least at the start and end of a sample sequence. If the drift between two bracketing injections of the same calibration standard exceeds 30 % (taking the higher response as 100 %%) the bracketed samples containing pesticide residues should be re analysed.’
 

Resolution

The idea behind Canned Calculations for SCIEX OS software is to provide a ready-to-go, user friendly, data processing solution containing all the calculations and flagging rules that can be imported into a results table created in the Analytics workspace.
The calculations do provide a plug-and-play approach, but the resulting custom columns in the results table require some additional interpretation after applying the calculations. Each calculation in the package should be evaluated and adjusted to suit each lab's needs, they should apply their own insights when interpreting method guidelines, when identifying the samples used for the calculations, when presenting the results and when linking different calculations.

Sample sets processed without bracketing calibration using the SANTE C15 guidance must be evaluated to ensure, that the internal standard peak area does not show a significant drift. To automate this, SCIEX generated a set of calculations and flagging rules that provide custom columns indicating if a sample should be flagged or not. The example result table below shows custom columns, generated with the canned calculations using a default data set (‘Documentation and sample data’), that is available when you are logged in on our website at this link in 'SCIEX OS Resources':
