"Selbsttätig wirkende Vorrichtung zur Niveauhaltung bei Austauscher- oder Chromatographiesäulen.""Automatic device for level maintenance in exchanger or chromatography columns."

BESCHREIBUNGDESCRIPTION

Die weite Verbreitung von Ionen-Austauschern und Chromatographiesäulen für Zwecke der analytischen und präparativen Chemie hat zur Entwicklung einer Vorrichtung geführt, die dazu dient, das Flüssigkeitsniveau über einer solchen Schicht zu halten und ein Trockengehen, das zur Zerstörung der Schicht führt, zu verhindern.The widespread use of ion exchangers and chromatography columns for purposes of analytical and preparative chemistry has led to the development of a device that serves to keep the liquid level above such a layer and a drying out, which destroys the layer leads to prevent.

Die Arbeitsweise mit Austauscher- oder Chromatographiesäulen ist gemeinhin so, daß ein Tropftrichter mit dem Elutionsmittel so einreguliert wird, daß eine gleichmäßige Höhe des Flüssigkeitsspiegels über der Schicht in der Säule gewährleistet ist.The procedure with exchange or chromatography columns is usually such that a dropping funnel with the eluent is regulated in such a way that a uniform height of the liquid level above the layer in the column is ensured is.

Geringe Temperaturänderungen oder Erschütterungen können jedoch dazu führen, daß ζ. B. eine über Nacht unbeaufsichtigt laufende Säule trockengeht, weil aus irgendeinem Grunde die Flüssigkeit schneller als einreguliert abläuft.However, slight changes in temperature or vibrations can cause ζ. B. an overnight unattended column goes dry because for some reason the liquid drains faster than regulated.

Dies verhindert zuverlässig die erfindungsgemäße Vorrichtung. Das Elutionsmittel tropft zunächst in eine Schwimmerkammer. Die Schwimmernadel verschließt den Ablauf so lange, bis eine gewisse Flüssigkeitsmenge in der Kammer ist und der Schwimmer sich hebt.The device according to the invention reliably prevents this. The eluent first drips into a float chamber. The float needle closes the drain until a certain amount of liquid is in the chamber and the float rises.

Falls der Tropftrichter leer gelaufen ist, kann also durch das geschlossene Schwimmerventil keine Luft in die Säule gelangen. Dadurch wird das Niveau in der Säule auch dann gehalten, wenn kein Durchlauf von Elutionsmitteln mehr stattfindet. Ein Ventil im Oberteil der Reguliervorrichtung sorgt für den Druckausgleich zu Beginn der Elution.If the dropping funnel has run empty, no air can get into the column through the closed float valve. As a result, the level in the column is maintained even when no more eluents are flowing through. One valve in the upper part of the regulating device ensures pressure equalization at the beginning of the elution.
