More recently Wong (2U, has reported the results of tests designed to characterize parameters of electronic silicones by Ther-mogravlmetrlc, Fourier Transform-Infrared, and Gas Chromatography/ Mass Spectrometry. This work has concentrated upon condensation-cure materials used within the Bell System, rather than the end-blocked free radical (addition-cure) silicones.

It is not possible to discuss all the methods available for characterizing foods critically and systematically in a single volume. Methods pertaining to interfaces (food emulsions, foams, and dispersions), fluorescence, ultrasonics, nuclear magnetic resonance, electron spin resonance, Fourier-transform infrared and near infrared spectroscopy, small-angle neutron scattering, dielectrics, microscopy, rheology, sensors, antibodies, flavor and aroma analysis are included.

Simple and rapid spectroscopic methods, such as front-face fluorescence, attenuated total reflectance Fourier-transform infrared and nuclear magnetic resonance spectroscopies, have a great potential for investigation of the structure of fats in dairy products and of the relation between structure and texture. Although fluorescence, infrared and NMR spectroscopies are techniques, the theory and methodology of which have been exploited extensively in studies in both chemistry and biochemistry, the usefulness of these spectroscopies for molecular studies has not been yet fully recognized in food science. Fluorescence, infrared and NMR spectroscopies coupled...

The basic effects responsible for the properties of electrolyte solutions are ion solvation, ion 2issociation to ion pairs and higher ion aggregates with and without inclusion of solvent molecules. FTIR (Fourier transform infrared) and MW (microwave) spectra are a valuable source of information on ion-solvent and ion-ion interactions and yield factual knowledge on the structure and dynamics of electrolyte solutions. The efficiency of these methods is exemplified for solvation in aptotic and protic solvents, hydrophobic solvation, association to charged and neutral ion aggregates, and stability of ion pairs. 

The analysis of such systems is often complex. One solution to this problem is the use of preparative SEC, to provide fractions for subsequent analysis by off-line techniques such as mass spectrometry, Fourier transform infrared and nuclear magnetic resonance. This technique can also be used to isolate pure polymer fractions for subsequent use in SEC calibration. 

Silver ion TLC offers an effective means of fractionation of Upid mixtures into distinct fractions differing in the number of double bonds. It is often used to simplify the further examination with gas chromatography, GC-mass spectrometry, Fourier transform infrared, and so forth. Ag TLC serves also as an enrichment procedure for minor components and allows for more accurate estimation of their content and identity. Quantitative procedures have been developed for the determination of fatty acids and triacylglycerols by using Ag TLC and densitometry.

It is likely that further applicationsi of sophisticated instrumentation to analysis of silicates will appear in future literature. In addition to ESCA, SIPS, X-ray spectroscopy, laser Raman and dispersive infrared spectroscopy, newer techniques such as Fourier transform infrared and photoacoustic spectroscopy may be used as tools to characterize silicate structure. 

Abstract Spectroscopic methods such as NIR, Fourier transform infrared, and Raman are becoming increasing important in pharmaceutical research and manufacturing. This chapter reviews both quantitative and qualitative applications of spectroscopic analysis for pharmaceutical products. Several applications of these technologies to stability testing are discussed.
