6.3 Flow Cell
Important:
The flow cells of the detectors
UVD 170S/340S
and
UVD 160S/320S
are
not
interchangeable.
Important:
The resistance of the flow cell depends on the solvents. This applies
particularly to solvents which can form active radicals or peroxides.
6.3.1 Flow Cell Versions
The following flow cells are available for the
UVD 170S/340S
detector:
•
standard flow cell (order no. 5065.1810)
•
standard flow cell with PEEK capillaries (order no. 5065.1820)
•
preparative flow cell (order no. 5065.1800P)
•
micro glass capillary flow cell (order no. 5065.1800M)
Standard Flow Cell (Order no. 5065.1810)
The standard flow cell of the
UVD 170S/340S
has a volume of 10
µ
l and a path length of
9mm. The flow cell body is composed of PEEK with quartz windows and is thus 100%
biocompatible. The inlet capillary is factory-fitted with a single-part, handtight fitting. The
outlet is a PEEK capillary. Optionally, a PEEK capillary can be used for the inlet. The
maximum pressure rating of the standard flow cell is 100bar (10,000kPa).
Important:
When cleaning the flow cell (
→
section 6.3.4), please note that only the
lens retaining plates and the lenses may be removed.
Do not
attempt to
remove the flow cell body from its housing! Clean the flow cell body
together with the housing.
