Lachat History In 1981, Lachat Instruments introduced the world\'s first multi-channel flow injection analyzer, the QuikChem® IV which allowed up to four analytes to be determined simultaneously. In 1989, the second generation QuikChem® AE (Advanced Edition) was introduced which featured true multi-tasking and the simultaneous determination of up to seven analytes. The AE was also the first automated ion analyzer to have a true XYZ sampler, intelligent auto dilutor and a built-in Data Quality Management plan. 1994 saw the debut of the QuikChem® 8000 which accommodates up to eight analytical channels and enables the operation of both flow injection analysis and ion chromatography simultaneously and independently on the same platform. In 1999, Lachat continued its innovations with the introduction of the IC5000 Ion Chromatograph. Lachat Instruments was acquired by the Danaher Corporation on December 19, 2000.
