Stand-off Raman spectrometer for identification of liquids in a pressurized gas pipelines.
نویسندگان
چکیده
a stand-off Raman spectrometer has been developed to make observations of liquid samples within a gas pipeline. The instrument is based on a static Fourier Transform spectrometer. The high etendue offered by the instrument enabled four liquid samples to be measured from a distance of 2.4 m within a gas pipeline. Liquids were identified with depths less than 5 mm demonstrating that the concept is viable for active pipeline measurement.

A Novel Technique for Raman Analysis of Highly Radioactive Samples Using Any Standard Micro-Raman Spectrometer
A novel approach for the Raman measurement of nuclear materials is reported in this paper. It consists of the enclosure of the radioactive sample in a tight capsule that isolates the material from the atmosphere. The capsule can optionally be filled with a chosen gas pressurized up to 20 bars. The micro-Raman measurement is performed through an optical-grade quartz window. This technique permit...

About 20% of the electricity produced in the world is consumed in rotary equipment for conveying fluids such as water, gas, air, and other liquids, while the loss of energy consumption in this sector is more than 60%. The aim of this study is to evaluate different efficiencies in the pumping stations in the pressurized irrigation systems to address low energy efficiency issues in the pump stati...
متن کاملSingle-shot stand-off chemical identification of powders using random Raman lasing.
The task of identifying explosives, hazardous chemicals, and biological materials from a safe distance is the subject we consider. Much of the prior work on stand-off spectroscopy using light has been devoted to generating a backward-propagating beam of light that can be used drive further spectroscopic processes. The discovery of random lasing and, more recently, random Raman lasing provide a ...
