(LCMS) Viewing Detailed Actions or Results for System Check - MS Check
- Category :
Answer
This content is for LCMS-2050.
The following describes how to view detailed actions or results from using the [System Check]-[MS Check] function, particularly functions for automatically checking or determining the status of MS detectors (mass axis shift, FWHM, or intensity).
« Overview »
If [System Check] is executed with either [Difference], [FWHM], or [Intensity] selected for [MS Check], then the standard sample is automatically injected into the MS unit and measured and the results are compared to pass/fail criteria values to determine the pass/fail result.
Some settings enable additional automatic autotuning actions based on the pass/fail results.
Note: For instructions on changing criteria values for [Difference], [FWHM], or [Intensity], refer to Changing the System Check Pass/Fail Criteria.

« Masses Checked by MS Check Pass/Fail Determination »
Note: “(+)” indicates the positive ionization mode and “(-)” the negative ionization mode.
« Masses Checked by MS Check Pass/Fail Determination »
Note: “(+)” indicates the positive ionization mode and “(-)” the negative ionization mode.
Note: Autotuning abbreviated “AT” below.
« Differences in Actions for Each AT Setting »
« Interpreting Results »
→ The interface electric current value during MS check is displayed as reference information.
→ Mass axis shift, FWHM, and intensity results are displayed for each mass checked. If a result fails to satisfy a criterion, the corresponding parameter (mass axis shift, FWHM, or intensity) is also displayed.
If results from before and after AT are available ([Differences in Actions for Each AT Setting] field is highlighted with a background color), then results are displayed for both before and after AT.
If results from before and after AT are available ([Differences in Actions for Each AT Setting] field is highlighted with a background color), then results are displayed for both before and after AT.
→ Displays the criterion value and autotuning setting when MS check was executed.
“– –” is displayed in the criterion value field for parameters that are not selected.
“– –” is displayed in the criterion value field for parameters that are not selected.
→ Displays the last date/time AT was executed. Sample type and mode information is shown for reference purposes.
