Possible Causes
Apertured cells
Action
For single cell holder:
For cells with apertures of 2 mm or smaller,
always use flow cells and avoid removing it
between measurements.
For multicell transport:
Never use a multicell transport as a single
cell holder when apertured cuvettes are in
use (BLANK on position number 1 and
SAMPLE on all other positions) without doing
a zero cells measurement.
Avoid removing and replacing the cells during
a series of measurements.
Be sure that the clamp of the multicell
(89075D) is always closed then doing a
measurement.
In general use only cells with blackened
walls.
