Analytical techniques and automation

From the point of view with which the automation of analytical instrumentation has been approached above and taking Into account the distinction between analytical technique and method established in this chapter, analytical determinative techniques and automation can be related in two ways. 

In Table 1.3 are listed the Instrumental techniques most frequently used for detection with automatic analysers of any kind. Molecular absorption spectrometry (colorimetry) is by far the commonest of such techniques, followed by potentlometry (pH measurements and use of selective electrodes).

A given Instrumental technique can be considered to bear different relationships to different laboratory processes. Thus, spectrofluorlmetry can be automated by use of a mlcroprocomputer either by setting the desired Instrumental parameters (excitation and emission wavelength, silt width, Instrumental sensitivity, etc.) or by choosing the methodology (conventional, synchronous, synchronous-derivative, time-resolved, etc.) to be used. Automated data acquisition allows the Implementation of these alternatives (see Chapter 9). On the other hand, a fluorlmeter equipped with a flow-cell can be used as
