UV Analyst Software

(PC-Control software)

The PC application software UV/Vis Analyst takes the best features of the stand-alone version plus more powerful data processing, expanded data collecting, and storage capability. It comes standard with UV3/6 series PC models and is optional to stand-alone models.

The PC application software offers

1.      Photometric Mode

2.      Quantitative test (Standard curve)

3.      Wavelength Scan

4.      Kinetics

5.      DNA/Protein

6.      Multi-Wavelength

7.      System Utility

Quantitative Test (Standard curve)

Use up to 20 standards to establish standard curve. Four methods for fitting a curve:

1.     Linear fit

2.     Linear through zero

3.     Square fit

4.     Cubic fit

Multi-wavelength

Up to 20 wavelengths can be selected and multiple samples can be measured. (Auto cell changer is required to run multiple samples automatically)

Wavelength Scan

Automatically record peaks and valleys. The quantity of channels is unlimited; you can simultaneously store as many as desired. Post-run manipulation and processing includes:

1.     Re-scaling axes, curve.

2.     1^st to 4^th derivative.

3.     Smoothing, combination, zooming, overlap.

 Kinetics (Abs. VS Time)

The Kinetics mode may be used for scanning time course or reacting rate calculations. Abs. VS Time graphs are displayed on the screen in real time. Wait time, measurement time and time intervals may be entered.

Post-run manipulation includes re-scaling, curve tracking and selection of the part of the curve required for the rate calculation. Rate is calculated using a linear regression algorithm before multiplying by the entered factor.

 DNA/Protein

Concentration and DNA purity are quickly and easily calculated:

Absorbance ratios 260nm/280nm with optional subtracted absorbance at 320nm.

DNA Concentration=62.9*A₂₆₀-36.0*A₂₈₀

Protein Concentration=1552*A₂₆₀-757.3*A₂₈₀

Other wavelengths and factors may be entered.
