the general view bout the automated clinical chemistry analyser…i want to noe about…
=types and parts?
=function of each part?
=maintenance?
=safety and precautions?

Your question is too general I’m afraid because there are several clinical chemistry analysers to fit on this page. At my lab we use Hitachi 917 and I guess you can look that up on the net. There are other versions of Hitachi of course, but then again there are other brands as well, such as Monarch, IL, Elisa etc. The choice of analyser depends on a lot of factors for example throughput (how many results issued in a given time), number of parameters that can be measured, requirements for optimal function (water systems etc), what kinds of reagents are needed, how much they cost, what consumables (cuvettes etc) are needed and again their cost, what maintenance agreements the company can offer, what Quality Control program is needed etc etc.

Parts? There’s lamps or other sources of light for spectrophotometric tests, sample cuvettes and reaction cuvettes, probes (to aspirate reagents, samples, cleansing washes etc), sample rings, refrigeration units (for holding reagents), pumps, valves, a myriad of tubings and many more.

For maintenance there must always be a plan with schedules for daily, weekly, fortnightly, monthly and yearly maintenance, as well as parts that need to be replaced according to use or when they get damaged. Daily maintenance includes incubation water exchange, priming of reagents, washing of cells (sample cuvettes) etc etc

Safety? In general, precautions pertaining to the clinical setting must be taken, so for example gloves, overalls, goggles must be worn, and then there’s common sense so for example one mustn’t try to touch a sample from the sample ring when the analyser is working.

This is just a speck of the picture. I’d suggest you get hold of some books that the major companies issue periodically so that yo get a better idea of what you need.
