Kinetics :

This mode may be used for time course scanning or reaction rate calculations.
Abs vs time graphs is displayed on the screen in real time wait time and
measurement time up to 12 hours may be entered with time interval of
0.5,1,2,5,10,30 seconds and 1 min. Post-run manipulation includes re-scalling,
curve tracking and selection of the part of the curve required for rate calculation.
Rate is calculated using a linear regression algorithm before multiplying be the
entered factor.

DNA / Protein Test :

Concentration and DNA purity are quickly and easily calculated: Absorbance
rations 260 nm / 280 nm with optional subtracted absorbance at 320 nm.
DNA concentration = 62.9XA260-36.0XA280
Protein concentration = 1552xA260-757.3xA 280
