Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Dosieren von kleinen Volumina nach dem Oberbegriff des Anspruchs 1.The The invention relates to a device for dosing small volumes according to the preamble of claim 1.
Bei Anwendungen im Forschungsbetrieb sowie in Labors besteht insbesondere in der Analytik der Bedarf kleine bis sehr kleine Volumina zu fördern bzw. zu dosieren. Beispielsweise werden in der Massenspektroskopie Volumina von 1-2000 μl eingespritzt. Nach dem Stand der Technik werden für diese Zwecke speziell dafür vorgesehene aufwendige und teure Spritzenpumpen verwendet, die käuflich zu erhalten sind. Diese Spritzen sind jedoch sehr teuer in der Anschaffung und stellen daher eine erhebliche Kostenbelastung dar.at Applications in research and in laboratories exist in particular in the analysis, the need to promote small to very small volumes or to dose. For example, in mass spectrometry, volumes become from 1-2000 μl injected. According to the state of the art will be for these purposes especially for that intended consuming and expensive syringe pumps used, the commercially available too are obtained. These syringes are very expensive to buy and therefore represent a significant cost burden.
Die
deutsche Offenlegungsschrift
Es ist daher die Aufgabe der Erfindung eine einfache Vorrichtung zu schaffen, mit der kleine Volumina gegen hohe Drücke auf möglichst kostengünstigem Weg gefördert bzw. dosiert werden können.It Therefore, the object of the invention is a simple device to create, with the small volumes against high pressures on most cost-effective Promoted way or can be dosed.
Ausgehend vom Oberbegriff des Anspruchs 1 wird die Aufgabe erfindungsgemäß gelöst mit dem im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmal.outgoing From the preamble of claim 1, the object is achieved according to the invention in the characterizing part of claim 1 specified feature.
Mit dieser Vorrichtung können kleine Volumina gegen sehr große Widerstände gefördert werden, wie sie beispielsweise bei einer fused silica-Kapillare von 0,1 mm Innendurchmesser und einer Länge von 50 cm entstehen. Gegen diese Drücke kann mit einer Spritzenpumpe nach dem Stand der Technik nicht gefördert werden.With this device can small volumes against very large ones resistors promoted As with a fused silica capillary of 0.1 mm inside diameter and a length of 50 cm arise. Versus these pressures can not be delivered with a syringe pump according to the prior art.
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.advantageous Further developments of the invention are specified in the subclaims.

Die Vorrichtung kann beispielsweise zum Tunen und Kalibrieren einer Massen-sprektroskopieanlage verwendet werden. Weitere Einsatzmöglichkeiten finden sich in im Laborbetrieb, wo kleine Mengen präzise dosiert werden müssen, vor allem bei erhöhten Drücken.The device can be used, for example, for tuning and calibrating a mass spectrometry system. Further applications can be found in the laboratory, where small quantities must be precisely metered, especially at elevated pressures.
