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).
