SPECTROSCOPIC TECHNIQUES FOR SENSORS
2009The aim of this chapter is to give some basic elements concerning the utilization of absorption, lurninescence, Raman and Brillouin spectroscopies in the field of optical sensors. Particular attention is paid lo the diagnostics of thin films and to the applications of activated optical waveguides.

New type of photothermal spectroscopic technique
Applied Optics, 1992We propose a new type of photothermal spectroscopic technique. The experimental setup is simple and the experiment can be readily carried out, even in the difficult environments that are often required for opticaland surface studies of materials. Features of the method proposed here are nondestructive and noncontact; in addition, the simplicity of our ...

Chiroptical spectroscopic techniques based on fluorescence
Methods and Applications in Fluorescence, 2014Among the various chiroptical spectroscopic methods circular dichroism (CD), optical rotatory dispersion (ORD), Raman optical activity (ROA), the methods based on fluorescence have so far played a marginal role. Fluorescence detected circular dichroism and circularly polarized luminescence (CPL) were both introduced many years ago with important, but ...

Planar chromatography coupled with spectroscopic techniques
Journal of Chromatography A, 1995Recent progress in the combination of planar, or thin-layer chromatography (TLC) with a variety of modern spectroscopic techniques is reviewed. The utility of TLC for separation followed by mass spectrometry, with a variety of ionisation techniques, is illustrated with reference to a wide range of compound types including drugs, natural products ...

Spectroscopic Techniques and Chromatography
1985Chromatography is primarily a separation technique, the observed detector response being a record of the quantity of solute molecules eluted from the chromatographic system. Although procedures have been developed for identifying separated components in a mixture, for example the two column GC method (see Experiment 21, Chapter 9), and a system of ...

Chromatography and spectroscopic techniques
1999During the past decade considerable advances have taken place in digital and analogue electronics, personal computer systems and instrument design which has enabled dedicated gas chromatography (GC) and high performance liquid chromatography (HPLC) instruments to be designed incorporating compact integrated spectroscopic detectors, particularly mass ...
