Description
Basic Functions:
1, Photometry:
Test Abs., Transmittance and Energy by fixed Wavelength
2, 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
3, Kinetics:
Used for time course scanning or reaction rate calculations △A/t, can search all data
4, Multi-Wavelength:
Can test Transmittance and Abs. with 8 different wavelengths at most
5, Scanning:
Users can set the scan range from 190nm to 1100nm to test the max. Abs. peak value can do derivation, Arithmetical operations to the graph.
6, Biology:
6 methods: DNA/Protein, UV, Lowry, BCA, CBB and Biuret
