Some methods for pore structure analysis have been presented The adsorption of benzene and the evaluation of isotherms through the Dubinin - Radushkevich equation, the estimation of immersion heats in benzene, the adsorption of water at relative pressures of h=0.6 and 1.0, the size exclusion liquid chromatography with tracers of different molecular diameters and the one - point adsorption of nitrogen. Six active carbons are included in the investigations. It is not possible to obtain reliable values with the simple water adsorption method. The results obtained with other methods are compared with performances of adsorption of phenol from aqueous solutions as obtained from measuring equilibria and column dynamics. It is shown, that the rank of the results of pore structure analysis is the same as from the dynamic experiments. [Pg.491]

The determination of the molecular weight of nanoparticles is performed by gel permeation chromatography (GPC). The experimental setup consists of a high performance liquid chromatography system with a size exclusion column and a refractive index detector. The nanoparticles are usually freeze-dried and dissolved in tetrahydrofuran for analysis on the system. Poly(styrene) or poly(methylmethacrylate) standards are used to calibrate the column, to enable the determination of number average molecular weight (Mn), as in... [Pg.10]

The ELISA can be used as one component of a battery of analyses. Rarely is only one method used in isolation. Other tests include chromatographic methods such as reversed-phase high-performance liquid chromatography (HPLC), size exclusion chromatography, and physical structure analytical methods such as UV spectral analysis, mass spectroscopy, etc. [Pg.281]

Analysis of Coal Liquids by Size Exclusion Chromatography—Gas Chromatography—Mass Spectrometry... [Pg.183]

Size exclusion chromatography (SEC) separates molecules based on size in a short analysis time. Unlike other chromatographic techniques, SEC does not retain sample species in the column, the analysis time is fixed, and everything loaded onto the column elutes within a fixed time frame. The application of SEC is limited only to the solubility of the sample in a solvent. Since tetrahydrofuran (THE) is a good solvent for coal liquids, the separation of coal liquids by SEC can be easily achieved. [Pg.184]

Polysorbate 80 is widely used as a nonionic surfactant in liquid pharmaceutical products such as inhalation, suspension, and nasal suspension products, due to its properties of solubilization, reduction of surface and interfacial tension, and wetting. Direct analysis of Polysorbate 80 is quite time consuming. Size-exclusion chromatography (SEC) has been reported [5] in which a mobile phase contained the surfactant at concentrations above the critical micelle concentration. Polysorbate 80 appeared as a very broad peak and coeluted with other peaks, which makes quantification in Nasonex impossible. [Pg.89]
