Description
Basic Functions:
1, Photometry
Test Abs., Transmittance and Energy by fixed wavelength
2, Quantitative
Linear fit and Linear fit through zero two modes
a. Coefficient, Standard Sample input and Standard Sample read three modes to establish standard curve
b. Establish A=K1*C+K0, can search original data, graph curve, parameters settings
c. Can save 240 group curves, can test 240 data in each curve
d. 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
User can set the scan range from 190nm to 1100nm to test the max. Abs. peak value, can do derivation, arithmetical operationsto the graph.
6, Biology
6 methods: DNA/Protein, UV, Lowry, BCA,CBB and Biuret
