To measure the Absorbance and Transmittance
Quantitative
1. Coefficient Method
2. Standard Curve
Up to 10 standard samples may be used to establish a curve.
Four methods for fitting a curve through the calibration points:
Linear fit, Linear fit through zero, Square fit and cubic fit.
DNA/Protein Test
Concentration
and DNA purity and easily calculated:-Absorbance ratios 260 nm / 280 nm
with optional subtracted absorbance at 320 nm. DNA
concentration=62.9xA260-36.0 x A2B0 Protein
concentration=1552xA260-757xA280.
Wavelength Scan
1. The wavelength scan intervals are 0.1, 0.2, 0.5, 1, 2, 5 nm
2. High, Medium and Low scan speeds are available. They vary from 100 to 3600 nm/min.
3. Wavelengths
are scanned from high to low so that the instrument waits at high WL
and it minimize 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 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.
