Basic Fuctions:
-
- PhotometryTest Abs., Transmittance and Energy by fixed wavelength.
- Quantitative
Linear fit and Linear fit through zero two modes
- Coefficient, Standard Sample input and Standard Sample read three modes to establish standard curve.
- Establish A=K1*C+K0, can search original data, graph curve, parameters settings.
- Can save 240 group curves, can test 240 data in each curve.
- Double wavelength, Triple wavelength test functions.
-
- Kinetics
Used for time course scanning or reaction rate calculations AA/t, can search all data.
- Multi-Wavelength
Can test Transmittance and Abs. with 8 different wavelengths at most.
- Scanning
User can set the scan range from 190nm to 1100nm to test the max. Abs. peak value, can do derivation, arithmetical operations to the graph.
