Hydro series wet cell
!
Caution!
The flow cell is an optical device. Scratches to the surfaces of the cell may affect
performance.
Each Hydro dispersion unit will be connected to a Hydro series wet cell.
Two wet cells are available, for use with aqueous or non-aqueous based samples.
A standard wet cell for use with
aqueous samples, identified by a
blue badge
A chemically compatible wet cell for use
with non-aqueous samples, identified by a
red badge with an R
The dispersion unit continually circulates the sample/dispersant from the dispersion unit
to the wet cell and through the analyzer beam of the optical unit so that a measurement
can be performed.
The cell windows in the wet cell are critical parts of the measurement optical path of the
system and should be kept clean and free from scratches at all times. Refer to Main-
tenance on page73 for details on cell maintenance and cleaning.
Note: If the cell is not used for short periods (up to 24 hours), leave the cell and
beaker full of clean dispersant so that the cell windows do not dry out, leaving
smears or water marks on the window surface. If the cell is not to be used for
longer periods, remove and dry the cell windows.
