HPLC—See High pressure liquid

A series of planar chiral pyridine-fused ferrocene analogs (366) have been prepared and the enantiomers are resolved by chiral High performance (pressure) liquid chromatography (HPLC) see High Performance Liquid... [Pg.2076]

Practical inlet systems for attaching a high-pressure liquid chromatography (HPLC) column to a mass spectrometer utilize atmospheric-pressure ionization (see Chapters 8 and 11). [Pg.391]

HPLC. Is it high-performance liquid chromatography or high-pressure liquid chromatography or something else It s probably easier to consider it a delicate blend of wet-column chromatography and gas chromatography (see Chapters 20 and 24, respectively). [Pg.242]

The imstable seven-membered ring molecule disproportionates rapidly to form eight-membered SCjSj and a few minor components. The SejSj was characterized by chemical analysis, molecular weight determination, high-pressure liquid chromatography (HPLC), X-ray crystallography, and Raman spectroscopy and was shown to contain mainly the isomer 1,2,3-Se3S5 (see also 3.2-3.4). [Pg.183]

Tetrahydrofuran (THF), either distilled reagent grade or high-pressure liquid chromatography (HPLC) grade (see Note 1)... [Pg.147]

High-performance liquid chromatography (HPLC) uses high pressure to force the mobile phase through a closed column packed with micrometresized particles. This allows rapid separation of complex mixtures. Several operating modes of HPLC are possible (see also p. 205). These are ... [Pg.218]

A widely used photometer used as a high-pressure liquid chromatographic (HPLC) detector uses the intense 254-nm resonance line produced by a mercury arc lamp (see Chapter 6). Others employ a miniature hollow cathode lamp as a very-narrow-wavelength intense source. For example, a zinc hollow cathode lamp gives a line at 214nm that is adequately close to the maximum wavelength of peptide bond absorption (206 nm) so that it can be used to measure peptides and proteins. Details on the hollow cathode lamp are found in the section on Atomic Absorption Spectrophotometry. The hollow cathode lamp also has a long, useful Hfetime if a lower-current, nonpulsed power supply is used. j... [Pg.66]
