The development of small computers has helped in the simplification of GC-MS machines. It also greatly reduced the amount of time it takes to analyze a sample. Electronic Associates, Inc. (EAI) was a leading U.S. supplier of analog computers. In 1964, EAI began development of a computer-controlled mass spectrometer under the direction of Robert E. Finnigan. By 1966, over 500 gas-analyzer instruments were sold. In 1967, the Finnigan Instrument Corporation (FIC) was formed. In early 1968, delivered the first prototype quadrapole GC-MS instruments to Stanford and Purdue University. FIC was eventually renamed Finnigan Corporation and went on to establish itself as the worldwide leader in GC-MS systems.
