Description
a) An die Stelle der bisherigen Beschreibung Seite 1, Zeile 29 bis Seite 2, Zeile 4 einschließlich der Worte ». . . Feldes bewegt.« ist folgende Fassung getreten: Erfindungsgemäß erfolgt die kataphoretische Trennung eines in einer Flüssigkeit befindlichen Substanzgemischs in einem zwischen zwei Elektroden befindlichen porösen Träger in der Weise. daß dieser Träger von einer Flüssigkeit. gegebenenfalls einer Pufferlösung, im folgenden als » Medium « bezeichnet, quer, zweckmäßig senkrecht zur Richtung des elektrischen Feldes durchströmt wird und daß die das zu trennende Substanzgemisch enthaltende Flussigkeit an einer eng begrenzten Stelle des Tragers kontinuierlich zugeführt wird und die getrennten Substanzen an @on der Zufuhrungsstelle entfernten, vonemander getrennten Punkten entnommen werden.a) In place of the previous description, page 1, line 29 bis Page 2, line 4 including the words ». . . Field moves. «Is the following version stepped: According to the invention, the cataphoretic separation of a takes place in a liquid substance mixture located in a porous located between two electrodes Vehicle in the way. that this carrier is from a liquid. possibly one Buffer solution, hereinafter referred to as "medium", transversely, expediently vertically to the direction of the electric field is flowed through and that the to be separated Liquid containing substance mixture at a narrowly delimited point on the carrier is continuously supplied and the separated substances at @on the supply point distant, separated points.
Es wurde schon vorgeschlagen, eine zweidimensionale Verteilungschromatographie in der Weise durchzufuhren, daß die chromatographisch getrennten Substanzen durch Anlegung eines elektrischen Feldes unter Verwendung von zwei Elektroden eine we@tere Zerlegung erfuhren, Hierber wurde das zu trennende Substanzgemisch als einzelner Tropfen auf ein Filtrierpapier aufgebracht. das mit einer Pufferlösung impragniert und dann getrocknet wurde. Die chron@atographische Entwicklung erfolgte mit Hilfe eines zwe@phasigen Lösungsmittelsystems. wie z. B. Phenol- Wasser. Two-dimensional partition chromatography has already been proposed to carry out in such a way that the chromatographically separated substances through Application of an electric field using two electrodes an additional one Experienced decomposition, the substance mixture to be separated was hereby separated as an individual Drops placed on a filter paper. which is impregnated with a buffer solution and then dried. The chron @ atographic development was done with help a two-phase solvent system. such as B. phenolic water.
Nach erfolgter Trennung lagen die getrennten und gefärbten Substanzen als Einzelflecken auf dem Filtrierpapier vor. Zwecks Gewinnung der getrennten Substanzen mußten die einzelnen Flecken mit einem Lösungsmittel eluiert werden. Durch Verdampfen des Losungsmittels wurden dann die betreffenden Substanzen gewonnen.After separation, the separated and colored substances lay as single spots on the filter paper. For the purpose of obtaining the separated substances the individual spots had to be eluted with a solvent. By evaporation The substances in question were then obtained from the solvent.
Im Gegensatz zu dem bekannten Verfahren. das recht umständlich ist und nur die Gewinnung sehr kleiner Substauzmengen erlaubt. können bei dem erfindungsgemäßen, kontinu@erhch durchgeführten Verfahren in vergle@chbaren Zeiten erheblich größere Substauzmengen und in wesentlich ein facherer Arbeitsweise gewonnen werden. Das als Träger verwendete Filtrierpapier wird nicht mit einer Pufferlösung @@pragniert und getrocknet. sondern wird von einer Pufferlösung ständig durchflossen. Das zu trennende Substanzgemisch wird nicht einmalig aufgebracht, sondern ständig der strömenden Pufferlösung zugeführt, was eine rasche Trennung ermöglicht. b) An die Stelle der bisherigen Beschreibung Seite 2, Zeilen 43 bis 49 ist folgende Fassung getreten: Als fester poröser Träger, der von dem Lösungsmittel durchströmt wird, kann gebrannter Ton. Filtrierpapier, Zellstoff. Seesand. Kieselsäuregel oder Gele anderer Art verwendet werden. c) Die bisherigen Patentansprüche sind durch folgende Patentansprüche ersetzt worden: 1. Verfahren zur kataphoretischen Trennung eines in einer Flüssigkeit befindlichen Substanz gemischs in einem zwischen zwei Elektroden befindlichen porösen Träger, dadurch gekennzeichnet, daß dieser Träger von einer Flussigkeit, gegebenenfalls einer Pufferlösung, quer zweckmäßig senrecht zur Richtung des elektrischen Feldes durchströmt und daß die das zu trennende Substanzgemisch enthaltende Flussigkeit an einer eng begrenzten Stelle des Trägers kontinuierlich zugeführt wird und die getrennten Substanzen an von der Zuführungsstelle entfernten, voneinander getrennten Punkten entnommen werden.In contrast to the known method. which is quite cumbersome and only allowed the extraction of very small quantities of substauz. can in the inventive, procedures carried out continuously in comparable times, considerably larger Substauz quantities and can be obtained in a much more specialized way of working. That Filter paper used as a carrier is not coated with a buffer solution @@ and dried. a buffer solution is constantly flowing through it. That too The separating substance mixture is not applied once, but the flowing one is applied continuously Buffer solution supplied, which enables rapid separation. b) Instead of the The previous description on page 2, lines 43 to 49, was replaced by the following: The solid porous carrier through which the solvent flows can be fired Volume. Filter paper, cellulose. Sea sand. Silica gels or other types of gels are used will. c) The previous claims have been replaced by the following claims been: 1. Process for the cataphoretic separation of a liquid located Mixed substance in a porous carrier between two electrodes, characterized in that this carrier of a liquid, optionally a buffer solution, appropriately transversely perpendicular to the direction of the electric field flows through and that the liquid containing the substance mixture to be separated is continuously supplied at a narrow point on the carrier and the separated substances at distant from the feed point, separated from each other Points are taken.
2. Weiterbildung des Verfahrens nach Anspruch 1, dadurch gekennzeichnet, daß der Träger aus einem Gel besteht. 2. Further development of the method according to claim 1, characterized in that that the carrier consists of a gel.
3. Verfahren nach den Ansprüchen 1 und 2, dadurch gekennzeichnet, daß der Grad der erzielten Trennung durch Messung physikalischer Eigenschaften, wie Brechungsindex. Leitfähigkeit. Dielektrizitätskonstante u. dgl. kontrolliert wird. 3. The method according to claims 1 and 2, characterized in that that the degree of separation achieved by measuring physical properties, like refractive index. Conductivity. Dielectric constant and the like controlled will.
4. Vorrichtung zur Durchfuhrung des Verfahrens nach den Ansprüchen 1 bis 3, gekennzeichnet durch die Anordnung einer Zulaufstelle für das zu trennende Gemisch auf der einen Seite und von mehreren Ablaufstellen auf der anderen Seite des Trägers. 4. Device for performing the method according to the claims 1 to 3, characterized by the arrangement of an inlet point for the to be separated Mixture on one side and from several drainage points on the other of the wearer.
5. Vorrichtung nach Anspruch 4, dadurch gekennzeichnet, daß mehrere Trennvorrichtungen in der Bewegungsrichtung des Mediums hintereinandergeschaltet werden. 5. Apparatus according to claim 4, characterized in that several Separating devices connected in series in the direction of movement of the medium will.
