Wavelength
Scan
The wavelength scan intervals are 0.1, 0.2, 0.5,
1, 2, 5 nm
Hi, Medium and Low scan speeds are availabe. They vary from100 to 3600 nm /
min.
Wavelengths are scanned from high to low so that the instrument waits
at high WL. and it minimizes the degradation of UV sensitive samples.
Kinetics
This mode may be used for time course
scanning or reaction rate calculations. Abs vs time graphs is displayed on the scren in real time.
Wait time and measurement time up to 12 hours may be entered with time intervals of
0.5, 1, 2, 5, 10, 30 seconds and 1 min. Post-run manipulation includes re-scaling, curve tracking and selection
of the part of the curve required for the rate calculation. Rate is calculated using a linear
regression algorithm before multiplying by the entered factor.
