Axiom Analytical has announced its FCT-550 Flow Cell for the continuous analysis of natural gas and other gaseous or liquid process streams.
The new cell has been designed for near-infrared (NIR) process analysis under demanding conditions, including continuous outdoor operation in any environment.
A key to the performance of the FCT-550 is the use of Axiom Analytical's proprietary window sealing technique involving a direct sapphire to metal welded pressure seal.
A high degree of chemical resistance is assured by the fact that the only materials in contact with the process are sapphire, high nickel alloys, and a thin flash of either gold or PTFE.
The compliance required to withstand extreme temperature cycling is provided by the high nickel alloy seal which is compressed at high pressure prior to welding.
This approach eliminates fatigue and stress failures common with brazed seals as well as the limited lifetime characteristic of elastomeric seals.
The company claims the reliability of the Axiom seal has been proven by years of successful use in its FPT-850 Near-infrared and UV-Visible Transmission Probes.
These probes are widely used for on-line process analysis in the chemical, petroleum, and pharmaceutical industries as well as in process development and related PAT (Process Analytical Technology) applications.
The FCT-550 Flow Cell is available in a wide range of optical path lengths.
It can be incorporated into near-IR analytical systems employing analysers using diverse technologies such as Fourier transform infrared (FTIR), dispersive near-IR, or tunable diode laser (TDL) spectroscopy.
