Automated analysis is defined as the use of combinations of mechanical and instrumental devices to replace, refine, extend or supplement human effort and facilities in the performance of a given process, in which at least one major operation is controlled without human intervention, by a feedback mechanism. Due to the ongoing demand for speed in industrial chemical analysis, parallel automation processes are beginning to replace serial automation processes, especially in those areas where high numbers of assays or samples are expected. For in situ or on-line situations where sparse strategic sampling is the norm, serial automation will likely play a continued role. Expensive robotic arms, while powerful and flexible do not directly lend themselves to parallel automation systems unless the effort is made to combine them with specialized multichannel hardware. Such hybrid systems are powerful and useful but are extremely complicated to implement and maintain. Hybrid system a combination of both now a day change sinario of analytical field by rapid and multiple analysis of the analytes.
