Flowcell assembly
The function of the flowcell is to direct focused light coming from
the lamp module through a critically-dimensioned sample/solvent
flow path and then into the polychromator. Focusing is achieved
by quartz optics lenses internally fitted to the flowcell.
Figure 21 A typical flowcell (9 x 1). Arrows show the liquid flow path.
Flowcells are made of titanium and have a maximum working
pressure range of approximately 1000 psi. The lens retainers are
made of brass and the gaskets are made of Teflon
(FEP).
Whenever you change the type of flowcell installed in the
detector, you must perform a lamp calibration. Refer to page 100
