In addition to conventional liquid chromatography, supercritical fluid chromatography (SFC), using a supercritical fluid as mobile phase (mostly scf-C02), has attracted attention in the last decades [58, 164, 168, 169]. Supercritical fluids provide a favourable medium for the transport of solutes through a chromatographic column because they resemble a gas in terms of viscosity, a liquid in terms of density, and are intermediate between these two phases in terms of diffusivity. For some physieal properties of supercritical solvents, see Section 3.2. [Pg.494]

Section 5 contains five chapters that discuss such analytical separation methods as gas and liquid chromatography, supercritical fluid chromatography, electrophoresis, and ticld-flow fractionation. [Pg.1052]

Online applications are by far the most important utilization of diode array spectrometry. High-performance liquid chromatography, supercritical fluid chromatography, capillary electrophoresis, and flow-injection techniques produce enhanced sensitivity and structure-related information due to coupling with diode-array-based detectors. Emission of the microwave-induced plasma generated in atomic emission detectors for capillary gas chromatography is also analyzed by means of UV-Vis diode array instruments. [Pg.4473]

To determine the molecular heterogeneity of a real polymer system, combination of separation techniques with spectroscopic techniques is required. The polymer chains are usually first fractionated by means of a separation technique such as liquid chromatography, supercritical-fluid chromatography, or temperature-rising elution fractionation. The characterization step can be performed by using a molecular spectral technique, either off-line or as a detector for the separation techiuque. [Pg.422]
