Detection biological-physiological

Biological-physiological detection The methods involved here take account of the biological activity of the separated components independent of their physical or chemical properties [12]. [Pg.7]

Physical detection methods are based on inclusion of substance-specific properties. The most commonly employed are the absorption or emission of electromagnetic radiation, which is detected by suitable detectors (the eye, photomultiplier). The / -radiation of radioactively labelled substances can also be detected directly. These nondestructive detection methods allow subsequent micropreparative manipulation of the substances concerned. They can also be followed by microchemical and/or biological-physiological detection methods. [Pg.9]

Just like the physical and microchemical methods of detection, the indirect, biological-physiological detection procedures are very selective when apphed to thin-layer chromatography. Here it is not chemical functional groups or particular physical properties that are selectively detected but effects on highly sensitive biodetectors . The following detection techniques have been employed ... [Pg.109]

For biological/physiological detection, the separated compounds can be transferred to the biological system. Alternatively, bioautographic analyses, reprint methods, and enzymatic tests may also be applied. [Pg.836]

In principle it is possible to employ physical, microchemical and biological-physiological methods for detection in TLC (Fig. 2). [Pg.11]

Three types of detection methods for TLC may be distinguished, namely physical, microchemical and biological-physiological. The more common detection methods for polymer additives in TLC are given in Figure 4.8. Detection is an off-line process, thus several detection techniques may be used one after the other. [Pg.222]

Even quantitative determinations can be performed using biological-physiological methods. These are discussed by Jork and Weins [114] using the example of enzymatic in situ detection of pollutants. [Pg.147]

These methods of detection do not exploit chemical or physical properties but the biological-physiological activity of substances. They are mostly employed for the detection and determination of antibiotics, alkaloids, insecticides, fungicides, mycotoxins, cytotoxines, vitamins, hot or bitter substances, and saponines. [Pg.218]
