Brief Function Introduction
All methods are included as built-in standard; this eliminates the need of software. Online software update via internet.
The local control software includes functions such as: Photometry, Quantitative, Wavelength Scan, Kinetics,DNA/Protein, Multi-wavelength and System Utilities.
Up to 10 standard solutions may be used to establish calibration equation curve. There is a choice of four methods for fitting a curve through the calibration points: Linear fit, Linear fit through zero, square fit and cubic fit.
Up to 10 wavelengths may be entered, allowing the measurement of multiple wavelengths on a series of samples.
The Wavelength Scan intervals are 0.1, 0.2, 0.5, 1, 2, 5nm, and High, Medium and Low scan speeds are available. Scan speeds vary from 100 to 2000 nm/min. Wavelengths are scanned from high to low so that the instrument stand by 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. Post-run manipulation includes re-scaling axes, curve tracking and peak picking.
This mode may be used for scanning time course or reacting 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 intervals of 0.5, 1, 2,5, 10, 30, seconds and 1 min.
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.
Concentration and DNA purity are calculated by
Absorbance ratios 260nm/280nm or 260nm/230nm with optional subtracted absorbance at 320nm
Other wavelengths and factors may be entered.
