Taking a Measurement
To take a measurement using dual beam instruments (Ultrospec 7000/8000/9000)
insert a cuvette containing the reference solution in the reference cell holder and
a cuvette containing the sample in the sample cell holder and press the take
measurement button. The reference measurement will be automatically subtracted
from the sample measurement.
Note: Measurements will commence after the specified Delay period (if applicable).
A measurement can be stopped at any time by pressing the Stop button at the
bottom of the screen. All data collected to this point will be displayed on screen and
can be saved.
The data displayed in the table below the scan refers to the full measurement
range. To obtain data for a specific section it is necessary to add sections, this is
done as follows: Set the cursor to the desired start position by either pressing on
the scan or using the cursors, select t0 from the options menu, set the cursor to the
desired end position and select t1 from the options menu. This can be repeated to
add up to 4 discrete sections.
Note: Sections must be added in numerical order i.e. t1 must be added after t0, t2
after t1 etc.
With sections defined, the data displayed in the table below the scan is determined
by the position of the cursor. Only when the cursor is positioned in the section of
interest will this data be displayed.
A line of best fit can be added to any section by positioning the cursor in the
desired section and selecting the add line of best fit button from the options menu.
Note: Details of how to perform overlays, data manipulation and selecting saved
files can be found in the Trace Manager section.
