8.6 CALCULATING I/U CONCENTRATION
The instrument software allows the user to calculate
the concentration of a substance from the difference
between the photometric values at two time points in
the displayed kinetics scan.
To enter the calculation parameters press the function
key below the Process option and enter a Start Time,
an End Time and a Factor, pressing the Enter key to
confirm each value.
When all values have been confirmed the instrument
will calculate the concentration value according to the
following equation:
Conc (I/U) = [Abs
(start time)
– Abs
(end time)
] x Factor
The calculated concentration value will be displayed on
the kinetics mode screen.
8.7 SPECTRUM SMOOTHING
The photometric values of the measured kinetics scan
can be viewed by pressing the function key below the
Search option. The user can press the up and down
arrow keys to review each point in the scan in turn.
