Abstract

An automated bubble trap for a liquid chromatography system includes a bubble trap or reservoir with level sensing devices at spaced elevations so that the liquid chromatography system can be operated unattended on a day to day basis so long as the liquid level is maintained between the liquid sensing elevations. The automated bubble trap will correct a low level condition restoring the liquid level to proper limits. However if a dry line condition is inferred, then the automated bubble trap will shut down the system until the problem is resolved.
