List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE.The following table is split into two groups based on whether it has a graphical visual interface or not.
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.
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 ...
Once conditioned, the sample enters a sampling manifold and is measured by various gas analyzers, typically NO x and O 2 (and sometimes CO) for combustion turbines and engines running natural gas or diesel. NO x analyzers typically work using chemiluminescence. O 2 analyzers a magnetic field which attracts O 2 to measure the
A classical exhaust gas analyser. An exhaust gas analyser or exhaust carbon monoxide (CO) analyser is an instrument for the measurement of carbon monoxide among other gases in the exhaust, caused by an incorrect combustion, the Lambda coefficient measurement is the most common.
In some analyzers, the reliability of measurements is enhanced by calibrating the analyzer at the reference condition and a known span concentration. If the air would interfere with measurements, the chamber that houses the energy source is filled with a gas that has no detectable concentration of the gas being measured.
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.
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]
