H.2.3 Checking Resolution
After you determine laser threshold, calculate the resolution.
Determine if the resolution is acceptable for your application.
See Section 6.5.2, Calculating Mass Resolution.
Table H-6 lists a general rating scale for resolution and
molecular weight ranges for compounds acquired in Linear
mode.
Table H-6 Continuous Extraction Mode Resolution Rating Scale
Compounds < 10,000 Da* Compounds 10,000 to 20,000 Da Compounds > 20,000 Da
Resolution Rating Resolution Rating Resolution Rating
250 Acceptable 200 Acceptable 60 Acceptable
350 Fair 250 Fair 100 Good
500 Good 400 Good
____ ____
600 Very good 600 Very good
____ ____
* You may see better resolution than indicated when analyzing compounds below 1,000 Da due to
isotope separation.
