Abstract

Automation is the performance of operation without human intervention. Automation may involve operations likePreparation of samples, Measurements of responses, Calculation of results. There are different automatic methods we are adopting now a days like chromatographic systems ( GC, HPLC), automatic methods are also used for injecting samples accurately at nanogram and picogram level by using robotic technology. Main objective of automatic methods of analysis is to process large number of samples, determination of several components in the same sample, reduction of human participation, to avoid manual errors, lowering of consumption of sample or reagents. Mainly two different types of automated systems being used at present they are-Discrete analyzer, Continuous flow analyzer. This article mainly deals with the methods of automation their merits, demerits and procedure for operation of these automatic systems and main focus on continuous flow analyzer in which the large number of samples can be analyzed at a time. It can analyze up to 60 samples per hour which makes this instrument ideal and also increases its use in analyzing biological compounds like proteins, peptides and other biomolecules present in blood, plasma, urine. Automated gives rapid, accurate, precise, results without any kind of manual errors. By feature it seems like miniaturize which increases its use. By implementing automated methods one can easily reach the industrial expectation of analysing the sample at high speed, decreasing the manual errors and increase in accuracy of results. Key words: automated methods, GC, HPLC, discrete analyser, contioues analyser, robotic technology.
