The Technicon AutoAnalyzer II (AAII) ...
The AutoAnalyzer II is the best known and most successful Continuous Flow AutoAnalyzer in the world. It was introduced by Technicon® in 1972. It uses a special flow technique named "continuous flow analysis (CFA)" or more correctly "segmented flow analysis (SFA)". There are still many hundreds of systems in use around the world, many still with Technicon® logo.
The AutoAnalyzer II was discontinued in 1997 an replaced by the AutoAnalyzer 3 (AA3). SEAL Analytical now own & manufactures the AutoAnalyzer brand with service & support for the AutoAnalyzer II, replacement & upgrade modules & the new AutoAnalyzer 3 (AA3) HR systems.
HISTORY
The AutoAnalyzer SFA instrument was invented 1957 by Leonard Skeggs, PhD and commercialized by Jack Whitehead's Technicon® Corporation. The first applications were for clinical analysis, but methods for industrial analysis soon followed.
The Technicon® AutoAnalyzer II profoundly changed the character of the chemical testing laboratory by allowing significant increases in the numbers of samples that could be processed. The novel design based on separating a continuously flowing stream with air bubbles all but eliminated slow, clumsy, and error prone manual methods of analysis. This instrument single handedly changed the concept of days per sample to a mindset that hundreds, or even thousands, of tests are possible per day.
The Autoanalyzer II (AAII) is the instrument that most EPA methods for automated colorimetric analysis were written on and reference. The AutoAnalyzer II is a second generation segmented flow analyzer that uses 2 millimeter ID glass tubing and pumps reagent at flow rates of 2 - 3 milliliters per minute. Typical sample throughput for the AAII is 30 - 60 samples per hour.
The Technicon Industrial division including the AutoAnalyzer II was bought by Bran Luebbe in 1987. The AAII was replaced by the next generation AutoAnalyzer 3 (AA3) in 1995. SEAL Analytical is the only company authorized to supply Genuine Technicon / Bran Luebbe / SEAL Analytical Parts and offer Factory Trained Service and Support and consumables for the AAII & AA3.
