Title: Process and apparatus for the qualitative and quantitative separation of hydrocarbon mixtures
Inventor: ZOBEL HENNING DR
IPC: B01D15/08
Filed: 1993-04-15
Abstract: The invention relates to a process for determining polycyclic aromatic hydrocarbons in hydrocarbon mixtures and/or hetero-compound-containing hydrocarbon mixtures, such as mineral oils, petroleum and its processing product and liquid conversion products of coals and other novel carbon sources by means of multi-dimensional HPLC in on-line coupling of HPLC separation stages separating groups and individual compounds. The problem in the known qualitative and quantitative processes was that overlapping often occurred in the determination of polycyclic aromatic hydrocarbons and thus high systematic errors occurred. In the off-line coupling of normal-phase and reversed-phase HPLC, errors occur as a result of losses in the concentration of the reversed-phase eluate. The process according to the invention is characterised in that the hydrocarbon mixtures are fractionated multidimensionally and selectively by on-line coupling of an HPLC system having nonpolar, aprotic eluents and a separation column separating structural types to an HPLC system having a polar, protic eluent system and a suitable reversed phase separating aromatics. The outlet of the HPLC system separating structural types is connected to a cartridge which can be switched via a multiple-way valve and is packed with a phase material absorbing aromatics, which cartridge, after absorption of the aromatic structural types [lacuna] of the feed into the ...

Abstract: PCT No. PCT/DE94/00889 Sec. 371 Date Feb. 2, 1996 Sec. 102(e) Date Feb. 2, 1996 PCT Filed Jul. 27, 1994 PCT Pub. No. WO95/04951 PCT Pub. Date Feb. 16, 1995The invention concerns a planar electro-optical light-beam deflector with a line of prismatic deflectors, arranged side by side, exhibiting electrodes to which an electric voltage can be applied. It is essential to the invention that the light beam is conveyed in a Z-cut lithium niobate or lithium tantalate crystal, preferably in a monomodal layer waveguide extending along the surface of the latter, the prismatic deflectors each consisting of two triangular or prismatic zones in which a largely uniform polarization direction is generated by inversion of the polarization direction determined by the E-field vector in domains with spontaneous polarization in the opposite direction, each triangular zone exhibiting polarization in the direction opposite to that of the one adjacent to it, and that a rectangular electrode covering the triangular zones is attached to the upper side of the crystal and a counterelectrode to the lower side of the same. Achieved with the invented means is that a refractive index of the opposite sign is induced in neighboring triangular or prismatic zones when a voltage is applied between the electrode and counterelectrode, the refractive index distribution following a nearly ideal sawtooth curve. The invention furthermore concerns a process for the production of such a light-beam deflector.
