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.
Standard Curve
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.
Multi-Wavelength
Up to 10 wavelengths may be entered, allowing the measurement of
multiple wavelengths on a series of samples.
Wavelength Scan
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.
Kinetics
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.
DNA/Protein Test
Concentration and DNA purity are calculated by
Absorbance ratios 260nm/280nm or 260nm/230nm with optional
subtracted absorbance at 320nm
DNA Concentration=62.9*A260-36.0*A280
Or 49.1*A260-3.48*A230
Protein Concentration=1552*A260-757.3*A280
Or 183*A260-75.8*A230
Other wavelengths and factors may be entered
