Axiom Analytical has introduced the FCT Series Near-IR Transmission Sampling Systems for on-line analysis of chemical processing applications involving high temperatures and pressures.
Axiom's FCT sampling systems are designed for use in high temperature (to 350C), high pressure (to 350 bar) and/or high viscosity applications.
FCT systems are suited for analysing hot polymer melts as well as other sample types.
In these applications, the cells are often mounted in series with a die on a small extruder or in a rheometer loop on a larger extruder.
An FCT sampling system consists of a pair of standard FCP-090 fibre-optic coupled near-infrared probes mounted on an FCB Series flow fixture.
The fixtures are customised for individual installations.
The probes employ an extremely robust plunger insertion design, allowing them to be removed without damage, even in the presence of solidified polymer.
Axiom's welded metal seal design has permanently sealed thick sapphire windows into the probe structure.
This provides a robust and permanent optical seal, virtually eliminating the possibility of window breakage, chemical attack or mechanical seal failure, even after repeated thermal shock.
The probe body is fabricated from Hastelloy C-276 to resist chemical attacks and abrasion.
