Standards and Band Matching
15-27
Fig. 15-20. Entering the known quantities.
After you have entered a few quantities, the status of the remaining bands in
the list may change to O.R., meaning that the remaining bands are out of the
current range of values (based on their intensity and what you have already
entered).
Alternatively, the software may automatically calculate an unknown quantity
(if it is between two known quantities) and enter a value for it; in this case the
Status column will indicate that the quantity has been calculated (Calc.)
In either case, you can type a quantity directly into the Quantity column and
the status will change to Known.
Relative Deviation of Known Quantities
After three values have been entered, relative deviations are automatically
calculated and displayed in the Rel. Dev. column. These values are based on
the difference between the known value that you entered and the values that
would have been calculated from the calibration curve.
If the deviation value is too high, you may want to exclude a band from the
calibration curve. Click on the arrow button next to the problem band. A pop-
up box offers several different band status options from which to choose.
