hydrogen gas analyzer Applications

  • Hydrogen Fluoride (HF) Monitoring in Air

    Hydrogen Fluoride (HF) is a colorless gas that is used extensively in industrial applications. Fluoride monitoring is especially needed for aluminum plants that need to convert HF into fluorine for use in their processes. Any HF that escapes is a cost to the plant, so an HF analyzer is essential to keep track of and prevent the losses.

    Gas Detection Solutions for Aluminium

    Primary aluminium smelting generates large amounts of hydrogen fluoride gas (HF). Worker safety and ambient air quality concerns require that HF be monitored at several locations in smelters. Traditionally, a variety of chemical sampling methods have been used for HF monitoring in and around smelters. However, these methods are labour intensive and require ongoing maintenance and consumables. During the past decade, laser based HF analyzers have been replacing the traditional methods. Laser analyzers are compact, robust and reliable and provide accurate HF data. Fast response times that enable easy correlation of high HF emissions with work practices.

    Gas analysis & monitoring system for biogas analysis

    “Biogas” means a mixture of various types of gas (mostly methane) produced by bacterial fermentation in anaerobic conditions(absence of oxygen) of organic residues from waste, decaying plant, carcasses in putrescence. The analyzers of biogas by Infrared cells carry out the continuous analysis of CH4, O2, CO2, H2S and NH3. The whole process sees the decomposition of organic material by some types of bacteria, producing carbon dioxide, molecular hydrogen and methane(methane conversion of organic compounds).

    Gas monitoring instruments and systems for stack testing according to EPA test method 320

    The United States Environmental Protection Agency (EPA) has two stack testing methods for FTIR gas analyzers. Method 320 is an FTIR method for measuring wide range of organic and inorganic pollutants. Method 321 is a specific version for measuring hydrogen chloride HCl at cement kilns producing Portland cement. These methods define a quality assurance and control processes for verifying the accuracy of the results. The requirements for analytical equipment and software are defined on 40 CFR Part 60 Appendix B Performance Specification 15. Gasmet™ Gas Analyzers and Calcmet™ software have been designed to take the requirements of the performance specification into account.

  • Fuel Cells

    Hiden gas/vapour analysers, optimized specifically for fuel cell research, offer a number of key benefits over other analysis techniques: rapid response (critical for temperature programmed studies), wide dynamic range, repeatability and linearity, are all of the up most importance when analyzing processes - particularly those in the presence of hydrogen - with widely varying gas concentrations. These features provide for accurate, stable and reproducible analysis of low molecular weight species, over a wide concentration range, present in a hydrogen rich atmosphere, and are found to be invaluable in applications such as the conversion of hydrocarbons, or alcohols, to hydrogen (reformers) for use in Proton Exchange Membrane (PEM) Fuel Cells.
