User:Brsd617/Applied Analytics, Inc.

Applied Analytics, Inc. is a manufacturer of spectrophotometric process analyzers and sampling systems for the chemical, petrochemical, power generation, and pharmaceutical industries, as well as environmental applications. Their products employ absorbance spectroscopy to monitor the chemical composition in a process stream. Applications include Claus process efficiency in sulfur recovery units, ammonia slip analysis, CEMS analysis, and hydrogen sulfide in refining and downstream processes.

Company History
AAI was incorporated in 1995. Their current headquarters is in Concord, MA, USA. They maintain offices in Houston, Baton Rouge, Singapore, the United Arab Emirates, and India.

The OMA Series
The OMA-300 is AAI's flagship analyzer. Developed in the early 1990's as a versatile analyzer for aromatic hydrocarbons and hydrogen sulfide, the OMA-300 has since evolved to monitor various other compounds.

The TLG-837 Tail Gas Analyzer
In the mid 1990's, the technology behind the OMA-300 was adapted for use in Claus process tail gas monitoring. Branded as the TLG-837, the system uses a patented in situ demister probe for sampling.

Total Sulfur Analyzers
In the 2000's, AAI developed analyzers for total sulfur in both liquid and gas processes. The liquid process version uses a diesel engine and a pyrolyzer to combust sulfur compounds in the sample to SO2, at which point SO2 can be measure via UV fluorescence and correlated to total sulfur concentration. The gaseous process version is similar, but lacks the engine and uses UV absorbance as its measurement principle.

MICROSPEC Series
The MICROSPEC Series of analyzers contains more compact units designed for single-species monitoring and often serve as modular elements within larger systems. This series comprises the only products made by AAI that do not use diode array technology. MICROSPEC products make use of tunable diode laser spectroscopy, non-dispersive IR detection, and other technologies as means of analysis.
