PC Control Software as Standard
Up to 32 wavelength can be selected and multiple samples
Quantitative, Coefficient Method (Standard Curve)
Use up to 32 standards to establish standard curve and methods:
Linear fit - Linear through zero - Square fit - Segmented
DNA/Protein Test
Concentration and DNA purity are Quickly and easily calculated: Absorbance ratios 260nm/280nm with optional subtracted absorbance at 320nm.
DNA Concentration =62.9 x A260 - 36.0 x A280
Protein Concentration =1552 x A260 - 757.3 x A280


This mode may be used for time course scanning or reaction rate calculations. Abs. vs. time graphs are displayed on the screen in real time. Wait time and measurement time up to 12 hours may be entered with time intervals of 0.5, 1, 2, 5, 10, 30 secs and 1 min. Post-run manipulation includes re-scaling, curve tracking and selection of the part of the curve required for the rate calculation.
Wavelength Scanning
The wavelength scan intervals are 0.1, 0.2, 0.5, 1, 2, 5 nm, and Hi, Medium and Low scan speeds are available. Scan speeds vary from 100 to 23000 nm/min. Wavelengths are scanned from high to low so that the instrument waits at high wavelength. This minimizes the degradation of UV sensitive samples. Precise control of filter and lamp changes means that their effects are not seen on the final scan.
