LI- 2904 Software

Basic Mode:

To measure the absorbance and tranmittance.

Quantitative:

1.       Coefficient method.

2.       Standard Curve up to 10 standard samples may be used to establish curve. Fore methods for fitting curve through the calibration points: Linear fit, Linear fit through zero, square fit and cubic fit.

DNA/Protein test:

Concentration and DNA purity are quickly and easily calculated: Absorbance rations260nm/280nm with optional subtracted absorbance at 320nm. DNA concertration = 62.9xA260-36.0 X A280 protein concertration = 1552xA260-757.3xA 280

Wavelength Scan:

1.       The wavelength scan intervals are 0.1,0.2,0.5,1,2,5 nm.

2.       Hi, Medium and low scan speed are available. They vary from 600 to 1200nm/min.

3.       Wavelength are scanned from high to low so that the instruments waits at high WL. And it minimizes the degradation of UV sensitive samples.

Kinetics:

This 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 and measurement time up to 12 hours may be entered with time interval of 0.5,1,2,5,10,30  seconds and one min. Post-run manipulation includes re-scalling, curve tracking and selection of the part of the curve required fro rated calculation. Rate is calculated using a linear regression algorithm before multiplying be the entered factor.
