Chromate 4300 - 4.2.4 % Absorbance Mode; 4.2.5 Point-to-Point Mode

24 ChroMate™ Operator’s Manual Doc. 4300 Rev. E
4.2.4 % Absorbance Mode
% Absorbance:
Description:
This mode is a point-to-point calibration
mode which calculates a % absorbance for
each sample and calibrator in addition to a
concentration value.
The highest absorbance calibrator is
assigned a value of 100% and each sample
and calibrator absorbance is calculated as a
percentage of this value and displayed in
the Interpretation field of the report. This
mode does not support ln, logit or log
scales for the absorbance axis.
The instrument accepts a number of
calibrators (from 2 to 7) read singly or in
multiple numbers.
Blanking, graphing, and editing options are
available.
4.2.5 Point-to-Point Mode
Point to Point:
Description:
The instrument accepts a number of
calibrators (from 2 to 7) read singly or in
multiple numbers.
It then calculates concentrations based on
the point-to-point calibration curve.
Data may be entered for linear-linear,
ln ( = natural log)-linear, linear-ln, or
ln-ln calculations.
Blanking, graphing, and editing options are
available.
