“…The use of on-line chemical reactions can be very selective for certain chemical families (e.g., amino acids, sugars). This technique has become widespread in column chromatography, both gas and liquid, and is even the principle underlying many detection schemes in thin layer chromatography [64]. The identification of an unknown presupposes methods supplying far more information and consistent with the ready association of elements of this information with structural details of the corresponding compound.…”

“…26,27), that the analyte absorbs light to initiate the photochemical reaction. A photochemical reduction similar to that described above for Vitamin K1 has recently been used to detect a variety of compounds that have only very weak chromopliores in the UV-visible region, or which have none at all (Ref s. 31,32).…”

-Various luminescence techniques based on the use of intermolecular energy transfer phenomena for detection in liquid streams are discussed. The two distinct methods based on room temperature phosphorescence in liquid phases (RTPL), the sensitized and quenched RTPL, are described. In particular the potential of phosphorescence quenching is wide. It will be demonstrated that this method has considerable promise for the determination of organic compounds, but also as a detector for selected inorganic ions, e.g., N02, S032, Pt2+ in ion chromatography. Furtheron attention is paid to photochemically generated or photosensitized reactions. It is shown that photocheraical reactions can be used as a special type of post-column derivatization, and improvements in both sensitivity and selectivity have been demonstrated. The mechanisms for photoreduction of anthraquinone by isopropanol and for the sensitized photo-oxygenation of ethanol are discussed.

“…Instead of reagents it is also possible to pump photons into a system and to explore the resulting reactions for detection purposes. Examples have been dis cussed elsewhere (7). Here we only want to mention the difficulty of con trolling photochemical reactions.…”
