Counts displayed on the data tab concentration may have slight
rounding errors when comparing all channels to values with selected
channels enabled. The method for calculating concentration is to sum
the raw counts for each location, calculate concentration from sample
volume and then round. This may result in slight rounding errors when
comparing counts with all channels enabled versus concentrations with
selected channels enabled. The methodology utilized is covered in
ISO 14644-1 Annex D.
