Spectroscopic Probes support continuous NIR monitoring.
Press Release Summary:
March 4, 2014 - Used for on-line analysis of hydrocarbon process streams, FCP-020 withstands demanding conditions, including continuous 24/7 outdoor operation, and features window sealing technique involving direct sapphire to metal welded pressure seal. Sapphire, high nickel alloys, and thin layer of gold or PTFE are only materials in contact with process, ensuring chemical resistance. High nickel alloy seal, compressed at high pressure prior to welding, enables extreme temperature cycling resistance.

Axiom Analytical, Inc. Announces Robust Spectroscopic Probes for Continuous Near-IR Monitoring of Hydrocarbon Process Streams
Press release date: February 24, 2014
A key to the robust performance of the FCP-020 probes is the use of Axiom Analytical’s proprietary window sealing technique involving a direct sapphire to metal welded pressure seal (U.S. Patent 6,587,195 B1). This approach provides significant advantages over other sealing techniques. 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 layer of either gold or PTFE (application dependant). 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 high reliability of the Axiom seal has been proven by many years of successful use in the company’s 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 PAT (Process Analytical Technology) applications.
The new probes are intended to be used in pairs in conjunction with standard Swagelok fitting technology for process line attachment. This enables them to be incorporated into existing process lines with little or no modification. The optical path length is determined in part by the design of the probes and in part by the nature of the particular Swagelok cross or other fitting employed The resultant transmission cell can be incorporated into near-IR analytical systems employing analyzers using diverse technologies such as Fourier transform infrared (FTIR), dispersive near-IR, or tunable diode laser (TDL) spectroscopy.
