Method and system for desorption atmospheric pressure chemical ionization
ActiveUS7544933B2Minimizing chanceHigh sensitivityMaterial analysis by optical meansIon sources/gunsSolvent vaporDesorption
A desorption atmospheric pressure chemical ionization (DAPCI) system delivers a primary ion beam composed of an inert, high velocity gas and solvent ions to a surface to effect desorption and ionization of both volatile and non-volatile species present on surfaces. A electrode having a tapered tip is connected to a high voltage power supply. The tapered tip projects outward from a capillary carrying a high-speed flow of gas. A vapor of a solvent is mixed into the annular gas flow surrounding the needle. The gaseous solvent vapor is ionized in close proximity to the tapered tip by virtue of the high voltage applied to the electrode. The high-speed flow of gas and solvent vapor ions extending outward from the capillary is directed toward a substrate on which an analyte of interest may have been deposited. The solvent vapor ions can blanket the surface of the analyte causing a static charge build up that facilitates ion desorption and additionally can provide positive ion adducts of the analyte freed from the substrate surface that can be directed toward an atmospheric intake of a mass spectrometer or other instrument capable of studying the analyte.

The crushing and high voltage electrostatic separation process of waste printed circuit board includes first crushing waste printed circuit board into 5-20 mm fragments, then pulverized into 0.06-0.5 mm grains and final separating metal grains from non-metal grains. The pulverized grains are fed to separating roller in high voltage electrostatic separating apparatus homogeneously and bombarded with negative ions the corona electrode generates to be charged. The metal grains are discharged fast in the earthing roller and electrostatically attracted with the static charge the electrostatic electrode generates to separate from the separating roller and fall into the metal collecting area, while the negatively charged non-metal grains are repelled electrically by the electrode to maintain on the surface of the metal roller before being brushed with a brush to fall into the non-metal collecting area. Thus, non-metal grains are separated from the metal grains in low cost, high efficiency and no pollution.
