  • A novel spectrometer design for process and handheld infrared spectral measurements

    Introduction Infrared spectroscopy offers many unique advantages for measurements within an industrial environment. Historically, the technique has been used for a broad range of applications from the composition of gas and liquid mixtures to the analysis of trace components for gas purity analysis. In cases where a well-defined method of analysis is involved, such as the measurement of ...

  • Validation and calibration of a spectroscopic technique for determination of gas plume temperature

    Abstract Results are reported from a continuing program of research into the physics and spectroscopy of heated stack plumes. Simultaneous thermocouple and spectrometer measurements are used to study sideways—directed plumes from an internal combustion engine and a propane-burning plume generator. A previously-reported result, that the ratio of optically thin signals from two CO2 ...

  • Polonium-210 in cigarette tobacco

    Tobacco and tobacco smoke contain minute amounts of some natural radionuclides such as 210Pb and 210Po, which are carcinogens. Intake of these radionuclides results in an increase of radiation doses to lung cells and tissues. Samples of the most frequently smoked cigarette brands were collected from the local market of Riyadh City, Saudi Arabia. Activity ...

  • Global aerosols studied by NILU

    Aerosols scatter and absorb solar radiation and thereby influence the radiation in the atmosphere and the global climate. To understand the climate system and the ongoing climate change it is important to know the distribution of aerosols in the atmosphere. Satellites provide an extremely useful tool to study this distribution, especially since it is very inhomogeneous with respect to ...

  • The application of Flow Injection Technology to automating cold vapor MERCURY analyses

    This document describes the application of flow injection technology to cold vapor mercury analyses. It can be obtained from PerkinElmer by requesting method number ENVA-100. Appendices 1 and 2 show letters from the US EPA indicating acceptability through the Alternate Test Program for both drinking water and wastewater sample analysis. 1.0 Scope and Application 1.1 This ...

  • FTIR Spectroscopy

    Fourier Transform Infrared (FTIR) Spectroscopy bases its functionality on the principle that almost all molecules absorb infrared light. Only the monatomic (He, Ne, Ar, etc) and homopolar diatomic (H2, N2, O2, etc) molecules do not absorb infrared light. Molecules only absorb infrared light at those frequencies where the infrared light affects the dipolar moment of the molecule. In a molecule, ...

  • New technologies for measuring the humidity of biomass

    Methods applicable to a great variety of solid biofuels In recent years, systems have sprung up which use near infrared X-ray (NIR) spectroscopy, radio frequency (RF) and microwave spectroscopy as alternatives to the traditional method of measuring humidity by weight difference in the fuel burner. What these methods have in common is that they can be used for a great variety of solid biofuels, ...

  • Detection and measurement of GWGs in semiconductor fab facilities

    Problem Statement Various processes and tools in the modern wafer fab plant produce effluent streams that contain unacceptably high levels of perfluorocarbon GWGs (greenhouse warming gases). These effluent streams are abated by plasma incineration and wet scrubbers and other techniques. It is necessary to measure the destruction removal efficiency (DRE) of the various abatement methods ...

  • Why measuring the ambient NO2 without conversion?

    Nitrogen oxides NOx are pollutants that may have particular impact in terms of greenhouse gases, acidifying air etc ... issuance increased significantly since 1950 with the massive development of transport and industries. It therefore becomes necessary to provide measures always safer these pollutant gases, and to know the reliability of results. Currently, 60% of emissions of NO and NO2 are ...

  • Analox case study: Monitoring oxygen at Cranfield airfield

    Introduction For personnel safety, monitoring of oxygen levels was required as part of an experimental field campaign based at Cranfield airfield. This experiment was undertaken by researchers in the atmospheric physics group at Imperial College London. The researchers are interested in measuring Far-infrared radiance fields in the atmosphere ...
