Hematology analyzers (also spelled haematology analysers in British English) are used to count and identify blood cells at high speed with accuracy. [ 1 ] [ 2 ] [ 3 ] During the 1950s, laboratory technicians counted each individual blood cell underneath a microscope .
The company was founded by Caltech professor Arnold O. Beckman in 1935 as National Technical Laboratories to commercialize a pH meter that he had invented.. In the 1940s, Beckman changed the name to Arnold O. Beckman, Inc. to sell oxygen analyzers, the Helipot precision potentiometer, and spectrophotometers.
Roche Cobas 6000 Roche Cobas u 411 Beckman Chemistry analysers: Access (left); Synchron (right). Racks: for putting samples, quality controls or calibrations. Cobas 6000 These tubes are put in the racks for testing. Photometry is the most common method for testing the amount of a specific analyte in a sample. In this technique, the sample ...

The Coulter counter was initially designed for counting red blood cells, but with later modifications it proved effective for counting white blood cells. [60] Coulter counters were widely adopted by medical laboratories. [211] The first analyzer able to produce multiple cell counts simultaneously was the Technicon SMA 4A−7A, released in 1965 ...
The first impedance-based flow cytometry device, using the Coulter principle, was disclosed in U.S. Patent 2,656,508, issued in 1953, to Wallace H. Coulter. Mack Fulwyler was the inventor of the forerunner to today's flow cytometers – particularly the cell sorter. [6] Fulwyler developed this in 1965 with his publication in Science. [7]
This allows laboratory analyzers, computers and staff to recognize what tests are pending, and also gives a location (such as a hospital department, doctor or other customer) for results reporting. Once the specimens are assigned a laboratory number by the LIS, a sticker is typically printed that can be placed on the tubes or specimen containers.
Mr. Coulter developed the "Coulter Principle," a theory that gave birth to both the automated hematology industry and the field of industrial fine particle counting. His "Coulter Counter," a blood cell analyzer, is used to perform one of medicine's most often-requested and informative diagnostic tests, the complete blood count. [1]
