ion analyzed.
Mass Accuracy in Delayed Extraction mode
(difference between the mean of six measurements
and the theoretical mass of the sample)
• External Calibration—0.05%
• Internal Calibration—0.02%
Mass accuracy is the difference between the
measured and the theoretical mass of the
sample.
Sensitivity Routine detection of 5 fmol of neurotensin.
