High voltage electrical charge

High voltage electrical charge (HVEC) assisted extraction was found to increase the extraction efficiency and the content of total polyphenols from grape pomace (Boussetta et al. 2009). In comparison to PEF assisted method during polyphenol extraction from grape seeds, HVEC showed similar extraction efficiency to PEF, but differed in that it was... [Pg.495]

Once the molecular ions are produced they are usually accelerated and focused, using high-voltage electric fields and suitable electrodes, prior to injection into the mass analyser. A number of different mass analysis methods are now in use, and new techniques are continually being developed. However, all the methods described here share one thing in common they all separate ions on the basis of the mass/charge ratio mjz). [Pg.73]

Electrospinning is a method which uses a high voltage electric field (10-20 kV) to produce fibers from a suspended droplet of polymer melt or solution through a nozzle. The electrostatic field is applied to the end of a capillary tube where the polymer is suspended. A polymer jet is formed when the surfaee tension of the droplet is overeome by the electrostatic charge. The... [Pg.72]
