Tolerances and
non-systematic
errors
When creating search pattern files, make sure to
compensate for:
Positional tolerance (related to variability in the position of
the plate)
NOTE: Due to limited surface area and variability in the
position of the disposable inserts, do not specify more
than 384 positions for a disposable plate.
Total allowable tolerance (includes the positional
tolerance plus any non-systematic error introduced by
sample application)
Search pattern
radius
Note the following:
To ensure complete analysis, the radius of the search
pattern file used must include the radius of the sample
spot.
To prevent analysis of the wrong sample, the radius of the
search pattern used must not exceed half of the
center-to-center spacing minus the total allowable
tolerance (Figure 3-12).
