By M. Valcarcel

This new monograph offers a complete review of the cutting-edge of the automation of laboratory tactics in analytical chemistry. the themes were selected in keeping with such standards because the measure of consolidation, scope of software and such a lot promising developments. the 1st a part of the ebook starts with the elemental ideas at the back of the automation of laboratory approaches, then describes computerized structures for sampling and pattern therapy. within the moment half the critical different types of analysers are mentioned: non-stop, batch and robot. The 3rd half is dedicated to the automation of analytical instrumentation: spectroscopic, electroanalytical and chromatographic ideas and titrators. The final half provides a few examples of the applying of automation to medical chemistry, environmental toxins tracking and business method keep an eye on. The textual content is supplemented by way of 290 figures and 800 literature references. it really is written basically for scientists at once taken with laboratory paintings and people chargeable for business making plans and keep watch over, study centres, and so on.

I n thls case, the computer not only processes and displays data, but also acquires it from the experiment o r measuring instrument and controls I t via interfaced electronic or electromechanical elements actuated by voltage or current changes. g. when data must be acquired very rapidly or the experiment generates a vast amount of Information). I n addition, they feature a number of advantages over their off-line counterparts, namely: the operator i s relieved from the key role i n the process and i t s functlon is undertaken by an electronic Interface, thereby Computers in the laboratory 31 avoiding human errors; the computer acquires information dlrectly from the experiment and hence at a much higher frequency; the computer controls the experiment i n a faster and safer way than the operator does; the overall process i s therefore faster and more precise.

In additlon, the quality of some of the elements of the instruments is sometimes sacrificed i n order not t o raise costs too much by the incorporation of microprocessors. g. poorer spectral resolution), and i n increased maintenance. 8 SIGNIFICANCE AND SCOPE OF APPLICATION OF AUTOMATION The growing trend towards automation has brought about a substantial change i n laboratory work, not only because of the purchase of new analysers, instruments or modules, but also because of the profound alterations undergone by the operator’s mlssion.
