Inline continuous gas analysis is a necessary tool for effectively tracking emissions of many types. A tunable diode laser (TDL) can provide accurate continuous measurement of target gas concentration. With the proper installation configuration, the instruments exhibit no drift and are not subject to interference, offering a sustainable means of delivering needed process data.

Mettler Toledo, with the expansion of their GPro 500 Series of TDL instruments, now provides continuous gas concentration measurement solutions for carbon dioxide, carbon monoxide, oxygen, moisture, hydrogen sulfide, and hydrogen chloride.

Varying application conditions can present specific challenges to an effective installation of a TDL, so the GPro 500 is available in variants that accommodate a range of installation conditions.

  • The standard probe is a purged configuration for general use.
  • A non-purged version is suitable for reactor of other vessel installation.
  • Combustion process measurements are handled by the non-purged filter probe, with a sintered filter to prevent dust from entering the measurement cell.
  • High particulate combustion processes can be served by the filtered probe provided with a blow-back port. It allows high pressure instrument air to clean the filter.
  • A wafer version, for tight spaces and pipes, is also available.
  • Two adaptions are also available for use with existing sample conditioning equipment.
  • A retroflector adapter enables a cross-pipe measurement. It is designed to forgo the need for alignment, making installation simple.
Tunable diode laser gas analyzers provide an effective means of continuous gas concentration measurement for the process industries and combustion operations. Share your process and combustion gas analysis challenges with a product application specialist, combining your own valuable process knowledge and experience with their product application expertise to develop effective solutions.

Proper inlet air control can boost gas turbine efficiency
Gas turbines continue to enjoy an expansion in their use throughout the world. The benefits of using gas as a fuel are well recognized. Achieving high levels of fuel efficiency will be a goal of every operator, so understanding the nature of combustion and fuels can be useful in attaining optimum operating conditions.

Vaisala, a globally recognized leader in the measurement of temperature and humidity, was authored a white paper application note that explains how the temperature and humidity of inlet air can contribute to combustion efficiency, as well as providing recommendations for measuring these parameters in gas turbine applications.

The white paper is included below. Share your process measurement requirements and challenges with application experts. Combine your process knowledge with their product application expertise to deliver effective solutions.
