Auto Run Measurements
1. Perform a Blank measurement as previously described and then select the
Auto Run checkbox on the app Run screen. Pipette 1 μL of the sample
solution onto the lower sample surface.
2. Lower the arm for automatic measurements. Deselect the feature to perform
new Blank measurements. Note: This feature may be used for both
microvolume and cuvette mode measurements.
Sample Measurement Modes
•
Measurement mode selections are made using the drop-down menu found
next to the Measure button on the Run screen.
•
The Microvolume mode uses 1.0 μL samples pipetted onto the sample
surface.
•
The microvolume Short Path mode requires 0.5 μL samples pipetted onto the
sample surface. This mode is for high concentration samples and does not use
the 0.5 mm pathlength.
•
The microvolume Fast Mode option is primarily for samples in the range
measured by the 0.5 mm pathlength although it may be used for higher
concentration samples .
•
The DS-11+ enables the use of 10, 5, 2, 1, 0.5, 0.2 and 0.125 mm pathlength
Cuvette modes.
• Report screens will include actual absorbance values measured using a
specific cuvette pathlength. Graph screens will display all cuvette
absorbance values normalized to a 10 mm value.
•
A new Blank measurement must be made when changing between
microvolume and cuvette modes.
