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

standard in the

same sample

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.
