4.2. Flow cells
WARNING
AVERTISSEMENT
Not certified for hazardous environments
Non certifié pour les environnements dangereux
WARNING
AVERTISSEMENT
Test for leaks after installation with non-hazardous
chemistry before resuming normal operations.
Testez les fuites après l'installation avec des produits chimiques
non dangereux avant de reprendre les opérations normales
The flow cell assemblies contain a pressure vessel and have been designed to withstand the
analyte conditions that are specified on your product label. For detailed technical drawings,
contact Keit.
4.2.1. High flow cell - ASM1392
The high flow cell can be secured to the end of the probe for continuous analysis of your
process. The flow cell is fitted with two ¾” NPT ports on opposing sides, to accommodate a
high flow rate offshoot pipe from the main process, passing the liquid in front of the ATR. This
is an alternative to installing the IRmadilloNA into a main pipeline.
It is fixed in place using a tri clamp that locates over the rear of the flow cell and two semi-
circular collars that fit around the probe. Ensure that the C-pieces make good contact with the
probe and that the pins are seated inside their corresponding holes then use the clamp to fit
the cell to the probe, clamping against the C-pieces. The clamp does not need to be tightened
with significant force, we recommend tightening the thumbscrew until resistance is felt + 1
turn.
The flow cell can be rotated through 360° to accommodate the user’s installation. Please
ensure that the flow through the cell is turbulent.
Maintenance and inspection method
: Visually check that all O-rings inside the cell have not
perished. They should show no signs of swelling, tearing, or degradation. Also inspects the
clamp and C-pieces for any signs of degradation, cracks, or damage. If the clamp and/or the
C-pieces show signs of significant wear, do not re-fit them. Contact [email protected] for
advice.
Do not use impact (e.g. a hammer) to separate components if the probe becomes stuck in the
flow cell.
