Fiber Optic Process Flow Cells
The Fiber Optic Process Flow Cells (FOPFC) are developed for
in-line absorbance measurements. The Process flow cells are
available with different optical path lengths and can be easily
coupled to our comprehensive line of fiber optic cables and
bundles through SMA connectors.
The FOPFC is comprised of the sensor body, emitter focusing
optics and receiver focusing optics assemblies to couple to
fiber bundles with industry-standard SMA connectors, linking
the process to the spectrometer. The FOPFC has a modular
design, standard process flange connections and is optimized
for use in harsh environment with high temperatures and
high pressures. SMA connector protection caps are available
on request.

In-Line Flow cells
The in-line flow cells have been developed for in-line absorption measurements.
The flow cells can be delivered for different line sizes: 1/4",
1/2" and 1" diameter.
The flow cells consist of Swagelok union cross tube fittings
and 2 UV/VIS/NIR collimating lenses.
Flowcell-1/4" and 1/2"
The optical path is depending on the size of the flowcell; the
1/4" has 5 mm optical path and the 1/2" has 10 mm optical
path and the 1" flow cell has 20 mm optical path. The flow
cells have SMA905 connectors for easy coupling to our comprehensive line of fiber optic cables and bundles. The 1/2"
flow cell is also avialable with variable focusing to optimize
light throughput in the (D)UV spectral range.

Micro Flow Cell
Micro HPLC flow cell with temperature control
Micro flow Z-cell
The micro flow cells are Z-cells that can be easily coupled to
1,5 mm PTFE tubing with 0,5 mm inner diameter for in-line
absorption measurements and HPLC applications. For the
micro HPLC cell a temperature control is possible using a
Peltier element controlled by a computer and connected via
the RS-232 interface. The Z-flow cells can be coupled with
2 special fiber optic cables (see below). The Micro HPLC
connects directly to SMA adapters.

Long Path Flow Cells
The LFC was developed to measure low-concentration
aqueous samples. LFC series flow cells are available in 50
mm, 100 mm, 500 mm, 1 m and 2 meter path lengths
for absorption measurements. All LPC flow cells are useful
for measuring low-volume, low-concentration (ppb-ppt)
aqueous samples, and can be used for discrete or continuous
flow cell sampling.
The LPC Long Pass Flow Cells consist of 550-micron inner-diameter fused silica tubing with a low refractive index polymer
and with an internal volume of 240 µl/meter. The tubing has
chromatography tube fittings for liquid flow. All LPC Flow
Cells couple easily via SMA terminations.
LPC´s can be used in a wide variety of applications, such as
liquid chromatography detection, drinking water analyses,
as well as environmental and oceanographic monitoring
systems.
