INDEX polarography

Specifications for modem detectors in HPLC are given by Hanai [538] and comprise spectroscopic detectors (UV, F, FUR, Raman, RID, ICP, AAS, AES), electrochemical detectors (polarography, coulometry, (pulsed) amperometry, conductivity), mass spectromet-ric and other devices (FID, ECD, ELSD, ESR, NMR). None of these detectors meets all the requirement criteria of Table 4.40. The four most commonly used HPLC detectors are UV (80%), electrochemical, fluorescence and refractive index detectors. As these detectors are several orders of magnitude less sensitive than their GC counterparts, sensor contamination is not so severe, and... 

Riley, T. and Watson, A., Polarography and Other Voltammetric Methods, ACOL Series, Wiley, Chichester, 1987. This is the best of the three ACOL electroanalysis texts (although again out of print). Its structure and examples are well chosen and well executed. Unfortunately, as with the other ACOL texts, the lack of an index and the irritating format may prove annoying to many readers. 

Other techniques previously described for general investigation of tautomeric equilibria (76AHC(S1)1> involve heats of combustion, relaxation times, polarography, refractive index, molar refractivity, optical rotation, X-ray diffraction, electron diffraction, neutron diffraction, Raman, fluorescence, phosphorescence and photoelectron spectroscopy, and mass spectrometry. The application of several of these techniques to tautomeric studies has been discussed in previous sections. Other results from the more important of these will be referred to later in this section. 

Table VII is an index to the techniques employed. For the sake of brevity polarography is excluded from It, as pure water Is from Table VI and as the dropping mercury electrode is from Table VIII, but for each of the other fifty-odd techniques that are included in this volume an entry like...

Table VIM Is an index to the indicator electrodes employed It provides access to all of the data obtained with mercury-pool, carbon-paste, rotating disc, and each of the numerous other electrode materials and configurations represented in Table I, with the single exception of the dropping mercury electrode, which is omitted here for the same reason that polarography is omitted from Table VII.

Other Methods. Turbidimetry, light scattering and refractive index measurements are spectrophotometric methods used to obtain surfactant cmcs. Viscosity, diffusion coefficient measurements, flow injection analysis and electrochemical methods (potentiometry and polarography and even...

The solvent index is arranged according to single solvents, nonaqueous-aqueous mixtures and nonaqueous-nonaqueous mixtm-es. Individual solvent systems are indexed accordii to solubilities, pKsp, emf, potentiometric titrations, vapor pressure, cryoscopy, heats of solution, polarography, ligand exchange rates, electrode reactions, electrical double layer, spectroscopy, and organic electrolyte batteries.
