Spectroscopic tools for remote sensing of greenhouse gases CH 4, CF 4 and SF 6

Abstract Highly symmetrical molecules such as CH 4, CF 4 or SF 6 are known to be atmospheric pollutants and greenhouse gases. High-resolution spectroscopy in the infrared is particularly suitable for the monitoring of gas concentration and radiative transfers in the earth's atmosphere. This technique requires extensive theoretical studies for the modeling of the spectra of such molecules ...

Advanced gas detection technology supports arctic greenhouse gas research

Enormous quantities of greenhouse gases (GHG) exist within Arctic ice and frozen soils, so with the threat of global warming, a clear understanding of the relationship between GHG in the atmosphere and in the ice/soil is vital because melting of permafrost could cause a dangerous climate tipping point. There can be few more challenging environments for monitoring gases, but PhD researcher Martin ...

Overview of Rotating Disc Electrode (RDE) Optical Emission Spectroscopy for In-Service Oil Analysis

Introduction The basis of modern oil analysis is the use of optical emission spectroscopy (OES) to measure the ppm (parts per million) levels of wear metals, contaminants and additives in oil samples. Whatever else an oil lab may measure, a multi-elemental analysis is the core of in-service oil analysis. This paper gives an overview of Rotating Disc Electrode Elemental Spectroscopy and its ...

Comparing TGA, FTIR and fixed filter infrared analyzers for measuring soot levels in in-service lubricants

Measuring soot in diesel engine oil has become more important as soot levels get higher due to exhaust gas recirculation. As soot isone of the key indicators for the condition of the oil, diesel engine maintenance programs performing regular soot checks can realize cost savings by extending drain periods and reducing used oil disposal. TGA (Thermal Gravimetric Analysis) is the traditional method ...
