The First In-situ Raman Gas Analyzer System (RGAS) from Scientific Instruments with Kaiser Optical Systems

The commercialization of spaceflight presents Scientific Instruments, Inc. with new opportunities to serve this burgeoning market with accurate, reliable, and robust temperature probes for monitoring critical parameters of liquefied fuel delivery systems. All of our temperature probes are precision fabricated from 316 stainless steel and other space-compatible materials, and hermetically sealed with welded connectors. Any of our thermometers can be installed, with our most popular being our platinum resistance thermometers (PRT) and Si410 silicon diode elements.

Scientific Instruments, Inc., in collaboration with Kaiser Optical Systems, an Endress+Hauser Company, proudly presents the world’s first in-situ Raman Gas Analyzer System (RGAS) for the composition and calorific measurement of liquefied natural gas (LNG) products.

Unlike the competing technology of gas chromatography, the liquid does not need to be extracted, vaporized, or conditioned prior to analysis, nor is the technique susceptible to changes in pressure, flow, or two-phase flow. Excitation and signal data are carried safely over fiber optics, and a simple probe design enables enhanced flexibility for installation arrangement. Applications for RGAS include process control, inventory management, custody transferⱡ, and blending.

ⱡRGAS conforms to the now active ASTM standard D7940-14, “Standard Practice for Analysis of Liquefied Natural Gas (LNG) by Fiber-Coupled Raman Spectroscopy.”
