Applications Notes

Industrial Process Monitoring at Dow Chemical — Measuring Acetylene During Cracked Gas Hydrogenation

Engineers at Dow Chemical explain how LGR acetylene (C₂H₂) analyzers now enable them to follow a critical hydrocarbon process in real time, delivering important advantages over earlier gas chromatography methods.

Fast Industrial Process Monitoring: Trace H₂S Measurements in Reformed JP-8 Fuel

Engineers at Precision Combustion discuss the use of an LGR H₂S analyzer to screen hydrocarbons in real-time, prior to their use in solid oxide fuel cells (SOFCs). Even ppm H₂S can rapidly poison the anodes used in SOFCs.

Measuring Methane Venting Fluxes in Extreme (Arctic) Conditions

Read how scientists from Fairbanks, Vladivostok and Stockholm are using portable methane (CH₄) analyzers from LGR in a high-profile study showing the extent of methane release from a massive undersea reserve beneath the East Siberian Arctic Shelf (ESAS).

Isotope Hydrology: Monitoring Rainfall Events in Real Time

Jeffrey McDonnell and co-workers at Oregon State University describe how they have used an LGR isotopic water (H₂O) analyzer to reveal some unusual data about isotopic (δ¹⁸O and δ²H) variability during single events (rainstorms).

Cavity-Enhanced Laser Absorption Spectrometry for Industrial Applications

In this Gases & Instrumentation article, read about several diverse industrial process monitoring applications that are using OA-ICOS-based analyzers from LGR.

Greenhouse gas analyzer for measurements of carbon dioxide, methane, and water vapor aboard an unmanned aerial vehicle

Scientists from NASA report on their sucessful use of an LGR greenhouse gas (GHG) analyzer flown on an unmanned aerial vehicle (UAV) and deployed to make highly accurate, 1 Hz measurements of methane (CH₄), carbon dioxide (CO₂), and water (H₂O) vapor.

Spectral Contaminant Identifier for Off-Axis ICOS Measurements of Liquid Water Isotopes

Read about a software package from LGR that can automatically and accurately correct isotopic water (δ¹⁸O and δ²H) data for the effects of interference from simple alcohols. This now eliminates the need for pre-treatment in the case of naturally contaminated samples such as plant waters, soil extracts, etc.
