Laboratory analysers adapted to industrial processes

Occasionally, process analysers are chosen for a given type of analysis on the grounds of Its proven efficiency in the laboratory rather than its suitability for the process in question. This reasoning is unwise because the fact that a given method or technique is suited to laboratory requirements does not necessarily Imply that it is fit for application to an Industrial process on account of the differences between both extremes. In fact, there are four basic differences between laboratory and industrial conditions, namely  

Laboratory Instruments are usually well attended to. Their operation and maintenance are entrusted to skilled personnel. They are calibrated prior to each series of analyses and are cleaned thoroughly afterwards. Process analysers should not require much attention as this detracts from economy the personnel in charge of the analyser are generally unskilled and have a secondary interest in it —they are rather concerned with the process line. Maintenance should be kept to a minimum and the Instrument should be designed so as to avoid drifts resulting In the need for frequent calibration or, alternatively, be equipped with an autocalibration mechanism.
