2. Features for spectrum software (Optional):

Basic Mode



Absorbance, %T or Concentration measurements.


Up to 15 wavelengths can be selected and multiple samples can be measured. (Auto cell changer is required to run multiple samples automatically).

Quantitative (Standard Curve)

Use up to 12 standards to establish standard curve.

Four methods for fitting a curve:

a. Linear fit

b. Linear through zero

c. Square fit

d. Segmented


Wavelength Scanning

Interval: 0.1, 0.2, 0.5, 1, 2, 5 nm

Automatically record peaks and valleys.

Post-run manipulation and processing includes:

a. Re-scaling axes, curve

b. Smoothing, combination, zooming, overlap

c. 1st to 3rd derivative

Kinetics (Abs vs. Time)

The Kinetics 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, measurement time and time intervals may be entered. 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.
