Curve and Line Fitting
A straight line, quadratic or cubic curve may be automatically
fitted to a set of up to 30 standards. Fits are possible either
with an intercept or forced through zero. All entries are prompted
for simplicity of operation. With the possibility of using such
a large number of standards, duplicate or multiple standards may
be used for any given concentration. A quadratic curve is shown
here.
Editing and Storage
Any suspect standards observed by inspection of the screen display
may be deleted or replaced and a new fit produced. Up to 30 curves
may be stored, security protected, for future recall and processing.
Time Course Plotting
The course of any reaction with time may be followed by simply
entering the mode, selecting the wavelength and entering the duration
of the plot, the scale and absorbance range as prompted.
The data will be displayed on screen or plotted and is available
for reprocessing. Finally the data may be stored in security protected
memory for future use.
A typical time plot on the screen is shown on the left. A printout
is available by pressing the RUN key, or may be made in real time.
Reaction Kinetics
Reaction Kinetics is available with reaction plots to screen and
printer. Data may be reprocessed as required. Regression analysis
is applied to the user selected portion of the reaction plot and
results are reported in Units/Litre.
Rapid Change Sample Holders
Sample holders take only seconds to change without the use of any
tool. They are retained by two pillar thumb screws, and require
no adjustment after fitting saving valuable time.
