Compatibility between sensors and automatic and automated analytical systems is crucial as it allows two Analytical Chemistry trends to be combined (see Fig. 1.1). Probe-type and planar sensors can be used in automated batch systems including robot stations, as well as in continuous (mixed in-line/on-line) systems. On the other hand, flow-through sensors are only compatible with continuous configurations.

Future Trends. Methods of laser cooling and trapping are emerging as of the mid-1990s that have potential new analytical uses. Many of the analytical laser spectroscopies discussed herein were first employed for precise physical measurements in basic research. AppHcations to analytical chemistry occurred as secondary developments from 10 to 15 years later. 

Analytical instruments play an increasingly important role in modern analytical chemistry. The trend is not limited in chemistry but in all phases of natural science and technology, as one easily can watch in rapid progresses in molecular biology, nano-materials technology, and the related bio-medical reseai ch. Instiaimental developments can now even be a determining factor in the advancement of science itself. 

Before discussing the problems of control laboratories, it is important to have a clear picture of the revolutionary changes which have been, and still are, taking place in the field of analytical chemistry. One has only to observe the recent issues of Analytical Chemistry, noting especially the editorials of Murphy (14) and the articles of Muller (13), to recognize the trend away from the classical gravimetric and volumetric methods of 20 years ago. 

Miniaturization is a growing trend in the field of analytical chemistry. The miniaturization of working electrodes not only has obvious practical advantages, but also opens some fundamentally new possibilities (77-79). The term microelectrode is reserved here for electrodes with at least one dimension not greater than 25 pm. 

The current trend in analytical chemistry applied to evaluate food quality and safety leans toward user-friendly miniaturized instruments and laboratory-on-a-chip applications. The techniques applied to direct screening of colorants in a food matrix include chemical microscopy, a spatial representation of chemical information from complex aggregates inside tissue matrices, biosensor-based screening, and molec-ularly imprinted polymer-based methods that serve as chemical alternatives to the use of immunosensors.

The 1970 s demonstrated a trend chemistry is going out of analytical chemistry . However, what was not used anymore up-ffont for analysis came bade in the form of sample preparation techniques. For example, lUPAC devoted as much attention as ever before, but now to the chemistry needed to prepare the sample for measurement and to avoid losses and contamination. 

Many of the classical techniques used in the preparation of samples for chromatography are labour-intensive, cumbersome, and prone to sample loss caused by multistep manual manipulations. During the past few years, miniaturisation has become a dominant trend in analytical chemistry. At the same time, work in GC and UPLC has focused on improved injection techniques and on increasing speed, sensitivity and efficiency. Separation times for both techniques are now measured in minutes. Miniaturised sample preparation techniques in combination with state-of-the-art analytical instrumentation result in faster analysis, higher sample throughput, lower solvent consumption, less manpower in sample preparation, while maintaining or even improving limits.
