Concentration Measurement
In the concentration measurement mode samples may be measured either
by using a calibration standard, or entering a known factor relating
concentration to absorbance.
Curve And Line Fitting
A straight line, quadratic or cubic curve may be fitted to up to
30 standards, with or without an intercept at the origin. Standards
may be deleted and replaced and a new curve fitted.
Reaction Kinetics
Single and multi-cell kinetic measurements are possible with plots
and data displayed on screen. Data may be reprocessed and curves
stored, security code protected against tamper or deletion.
Multi Wavelength Assays
Assays are provided using either two or three wavelengths. A wine
colour assay is provided which may use up to ten different wavelengths.
Computations at up to four wavelengths are also provided.
DNA And Protein Assays
Protein analyses may be made using either the 2 or 3 wavelength
methods of Warburg and Christian. Also programmed are techniques
and analytical procedures for assays by Lowry, Bradford, Biuret
and BCA methods.
Ratio And Difference
Absorbance ratioing at 280/260nm, or two user selected wavelengths,
is provided for DNA purity assays. The scaled difference of absorbance
values at two wavelengths is also provided.
Cell Program
Using the various cell changers, measurements may be made on up
to 4, 6 or 8 cells at a single wavelength with cycle time and number
of cycles entered by the operator. A cell and wavelength program
may be combined.
Wavelength Program
Measurements may be programmed for 10 different operator selected
wavelengths with the cycle time and number of cycles selected by
the operator. A wavelength and cell program may be combined. |
