Sample Pathlength
All applications display the sample pathlength along the spectrum’s vertical axis.
Micro-volume absorbance measurements and measurements taken with nonstandard cuvettes
are normalized to a 10.0 mm pathlength equivalent. Here is an example.
Blank Button
Tap
Blank
to measure a blank for the selected experiment.
A blank must be measured before each group of similar samples. The blank solution is
typically the pure buffer that was used to resuspend the sample. For more information, see
Choosing and Measuring a Blank
.
Measure Button
Tap
Measure
to measure a sample for the selected experiment.
Samples must be properly isolated and prepared before they can be measured with the
instrument and the concentration must be within the instrument’s absorbance detection
limits. For more information, see

Note
The
Measure
button is enabled after a valid blank measurement is completed.
