Analytical Instruments Corporation was formed in 1973 around key personnel with experience dating back to the inception of process gas chromatography in the 1950s. Then AIC was a small company with a single dedication: the manufacture of gas chromatographic instruments. Today, AIC observes the same singular dedication.

While still small enough to give individual attention to each order, the company has grown to encompass a complete line of process and laboratory instruments; and IAC has staffing to handle any custom requirement or to provide complete package system responsibility.

At AIC quality continues to be the watchword...quality through adherence to customer specifications and delivery schedules with an inspection program to ensure that each instrument performs the job it is designed to do. In keeping with this attention to quality and performance, each instrument is truly designed with the user in mind.

AIC's unique combination of field experience and instrument design know-how results in gas analyzing instruments that are sophisticated in performance yet simple to operate and maintain.

The index page and the photograph below illustrate the basic components of a Distributed Control MC-503-based gas analyzer system employing a central computer and serial communication multiplexer with a microprocessor-based analyzer control module.

In the MC-501 Control Unit, AIC pioneered the application of microprocessors to control process gas chromatograph systems. The second generation MC-502 operates four analyzers simultaneously, incorporating the best features of a laboratory system. These features include continuous baseline tracking, true slope detection, all key components for automatic correction of elution time, various algorithms for component integration, etc. Now the third generation MC-503 control of Pipeline/BTU Analyzers is presented; and finally the Model 610A Laboratory Gas Analyzer, with its four detector types, is covered.

It should be noted, however, that process analyzers, pipeline/BTU analyzers and laboratory analyzers may be mixed in any combination up to a total of ten analyzers per system.
