Horiba, Ltd. (堀場製作所, Kabushiki-gaisha Horiba Seisaku-sho) is a Japanese manufacturer of precision instruments for measurement and analysis. They make instruments that measure and analyze automobile exhaust gas (80% share of the world market), [ 4 ] and environmental, medical and scientific applications.
Chlorine, sulfur and carbon (as coal) are cheapest by mass. Hydrogen, nitrogen, oxygen and chlorine are cheapest by volume at atmospheric pressure. When there is no public data on the element in its pure form, price of a compound is used, per mass of element contained. This implicitly puts the value of compounds' other constituents, and the ...
It is the first improved analyzer that is able to detect more than one component of a sample gas at one time. Earlier analyzers were held back by the fact that a particular gas also has lower absorption bands in the infrared. The invention of 1975 has as many detectors as the number of gases to be measured.
ORSAT analyzer. An Orsat gas analyser or Orsat apparatus is a piece of laboratory equipment used to analyse a gas sample (typically fossil fuel flue gas) for its oxygen, carbon monoxide and carbon dioxide content. Although largely replaced by instrumental techniques, the Orsat remains a reliable method of measurement and is relatively simple to ...
Elemental Analyzer System. The most common form of elemental analysis, CHNS analysis, is accomplished by combustion analysis. Modern elemental analyzers are also capable of simultaneous determination of sulfur along with CHN in the same measurement run. [3] [4] [5] [6]
A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector.It is non-dispersive in the fact that no dispersive element (e.g a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.
A small sample of flue gas is extracted, by means of a pump, into the CEM system via a sample probe.Facilities that combust fossil fuels often use a dilution-extractive probe to dilute the sample with clean, dry air to a ratio typically between 50:1 to 200:1, but usually 100:1.
With support from the Japanese Ministry of International Trade and Industry, the first Horiba IR infrared-based gas analyzer was sold in 1958, followed by a model for industrial use in 1962. [ 1 ] Masao Horiba visited the United States in 1958 as part of a study tour for delegates approved by the Japan Productivity Center.
