density (OD) is measured. After a few minutes have elapsed, a second
measurement takes place, after which the two ODs measured are com-
pared in terms of light intensity change, which is given in OD/min.
Chromogenic Test Result Calculation:
Percentage:
The percentage value is calculated form the
transmitted light intensity change per minute
(OD/min). The software of the instrument places a
calibration curve on the input function points, and
based on the curve, unknown relative concentration
values can be determined from the measured
light intensity change. The points of the calibration
curve must be determined from a dilution series by
the
user.
