Sensorex
manufactures fast response 50 and 200 microliter internal
volume flow cells. All cells are made of clear Acrylic or
Kynar (PVDF). Design includes 1/16" inlet and outlet
fittings. All cells use the standard, economical Sensorex
450C Flat Surface Combination pH/Reference Electrode.
The Sensorex pH Detector is designed for use with a variety
of instrumental techniques such as FIA, HPLC and IEF. It
also is used to continuously monitor the pH of low volume
flows in bench scale chemical systems.

The
50 and 200 microliter internal volume flow cells are available
in acrylic or PVDF. (Consult factory for details of other construction
materials.) They are supplied with inlet and outlet fittings sized
for standard 1/16" OD tubing. The cells' ports have 1/4-28
threads which accept a variety of other tube fittings.
The
small internal volumes of these pH Detectors are achieved by using
a flat surface pH electrode located at the top of the flow cavity.
The resulting rectangular cross-section flow path has no protruding
parts which could interfere with a clean, sweeping flow.
The
result of this design is the fast system response shown on the
performance curves in the data sheet. Download the PDF (to the
right) for complete details.
The
Flat Surface Electrode, Sensorex Model 450C, is a combination
pH/Reference electrode. It includes both a pH and reference half
cell. The reference electrode is a sealed, gel-filled design and
includes a peripheral, semi-porous polyethylene junction. For
applications where unwanted chemical reactions can occur in the
presence of silver or chloride ions, a double junction version
is available, Model 450CD. Use the double junction where proteins
precipitate in the presence of heavy metals such as silver. The
double junction design will prevent this precipitation. Both single
and double junction versions of this combination electrode are
supplied with a 76 cm (30 inch) cable and with a variety of connectors.
