•Usage and Application
1.Photometric measurement: Convenience to measure samples in the specified wavelength absorbance and transmittance.
Multi-wavelength detector is maximum simultaneous determination of 10 wavelengths.
2.Quantitative measurement: Establish automatically standard curve.
first after we order the third order curve fitting. Optional method: Single wavelength calibration,Double wavelength calibration,
Three point method,
3.Qualitative measurement: Including scaling, smoothing, filtering, detecting peak-valley etc.
4.Kinetics measurement: Calculate kinetics of enzyme reaction rate. There are scaling, smoothing, filtering, detecting peak-valley
and finding the derivative in a variety of graph processing methods for your choice.
5.DNA/RNA,Test function of protein calculates automatically the sample ratio and concentration.
