The number and placement of standards needed depend on
your application. See “Mass calibration standards” on
page 6-83.
Hint: You can use the same calibration file more than once
in a sequence run.
Sample and

position
You may see improved mass accuracy by spotting sample and
standard in as close together as possible within a sample
position (Figure 6-25). A standard spot within 1 mm of a
sample spot can yield mass accuracy close to that expected
for internal calibration.
NOTE: Use plates without laser-etched sample positions or
wells if you spot standard and sample as shown below.
