5.2.4. Safety
WARNING The flow cell assembly contains a pressure vessel.
WARNING
Do not exceed the pressure / temperature ratings stated on the
IRmadillo label.
WARNING
Visually inspect the assembly for signs of wear and tear before
use.
WARNING
Ensure that the flow cell is depressurised before disassembly.
WARNING
The flow cell parts will reach the same temperature as the
analyte.
WARNING
Fit protective devices to your analyte flow circuit to prevent
pressure spikes that exceed the permissible values.
CAUTION
The flow cell has restricted passages so liquids with suspended
particles may cause blockages. Excessive flow rates may cause
cavitation and erosion; consult with Keit if in doubt.
CAUTION
Ensure that the NPT fittings are attached prior to final assembly;
this avoids any side loads on the IRmadillo spectrometer which
may cause damage.
Prevent load being applied to the instrument by the installation. Connections must not apply
forces to the flow cell or the IRmadillo probe. Such loads increase the likelihood of leakage
and could cause the spectral performance of the instrument to become inconsistent.
5.2.5. Maintenance
Inspect the O-ring regularly and replace if it appears to have degraded; use plastic forceps to
remove the O-ring. This is particularly important if the chemistry that you are flowing through
the probe is known to cause swelling of the O-ring elastomer, or if the flow cell is often removed
to facilitate cleaning.
Inspect for signs of erosion caused by particulates in the analyte or by excessive flow
velocities. If in doubt, consult with Keit.
Regularly check fastener tightness using a calibrated torque wrench.
5.2.6. Cleaning
The flow cell may be cleaned using standard laboratory cleaning practices as appropriate for
your reaction. Inspect parts regularly for corrosion and damage. Replace O-rings annually.
The entire flow cell assembly, including the O-ring and fasteners, are also compatible with
standard autoclave procedures.
5.3. Flanged probe
A version of the IRmadillo spectrometer probe is available to allow connection to process
pipework with an ANSI/ASME B16.5 (other options available on request) compliant flange. A
hub is welded to the wall of the probe and a compatible lap-joint flange is mounted between
