NIR Probe can be fabricated in any length.
Press Release Summary:
Allowing process monitoring in full-scale batch reaction vessels, FDR-1800 Series Near-IR Diffuse Reflectance Probes utilize window sealing technique involving sapphire to metal welded pressure seal. Chemical resistance is ensured because only materials in contact with process are sapphire, high nickel alloys, and thin flash of either gold or PTFE. Device provides NIR diffuse reflectance data for nearly opaque samples and fluids with total reflectance of below 2%.
Original Press Release:
New Near-Infrared Probe Enables Large-Scale Chemical Process Monitoring by Diffuse Reflectance Spectroscopy
TUSTIN, Calif., February 24, 2009 - Axiom Analytical, Inc. has announced its FDR-1800 Series Near-IR Diffuse Reflectance Probes. The new probes can be fabricated in virtually any length and thus provide a unique capability for process monitoring in full-scale batch reaction vessels. Such vessels often include glass lining or heating coils, making probe entry from the side of the vessel impossible. However, an FDR -1800 probe can be made long enough for top entry even in the largest reaction kettles.
An important feature of the FDR -1800 design is the use of Axiom'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 flash 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 optical design of the FDR -1800 Series is highly efficient, providing high quality NIR diffuse reflectance data even for nearly opaque samples. In fact, good quality on-line data have been obtained with process fluids having a total reflectance of less than 2 %. This performance is due both the efficiency of the optics and to a unique design which greatly reduces stray light due to reflectance within the probe (U.S. Patent 5,818,996).
