Cell Test

The cell test measures the intensity of the deuterium and tungsten lamps over
the full wavelength range (190 – 950 nm), once with the flow cell installed, and
once with the flow cell removed. The resulting intensity ratio is a measure of
the amount of light absorbed by the flow cell. The test can be used to check for
dirty or contaminated flow cell windows. When the test is started, the 1-nm
slit is moved into the light path automatically, and the gain is set to zero. To
eliminate effects due to absorbing solvents, the test should be done with water
in the flow cell.
This test should be performed inititially with a new detector/flow cell. The values should be
N O T E
kept for later reference/comparison.
