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.
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.

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.
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 ...
The AutoAnalyzer is an early example of an automated chemistry analyzer using a special flow technique named "continuous flow analysis (CFA)", invented in 1957 by Leonard Skeggs, PhD and first made by the Technicon Corporation. The first applications were for clinical (medical) analysis.
The best known of Technicon's CFA instruments are the AutoAnalyzer II (introduced 1970), the Sequential Multiple Analyzer (SMA, 1969), and the Sequential Multiple Analyzer with Computer (SMAC, 1974). The Autoanalyzer II (AAII) is the instrument that most EPA methods were written on and reference.
An infrared spectroscopy correlation table (or table of infrared absorption frequencies) is a list of absorption peaks and frequencies, typically reported in wavenumber, for common types of molecular bonds and functional groups.
