Abstract
The invention comprises a method of regenerating a biosensor. It involves passing a background flow of fluid without reactive components through the flow passage. At a selected point in time a sample aliquot is injected into said background flow. At a point in time when a signal from said sensor is obtained the flow rate of the background fluid is increased. The invention also comprises a system for continuous monitoring of analytes in a biological fluid, the system having increased life by virtue of inherent regeneration of sensors employed. It comprises a biosensor ( ), a sampling device ( ) for providing a sample of said biological fluid, and means ( ) for passing a flow of a background fluid through said flow passage at selectable flow rates, means ( ) for injecting said sample into said flow of background fluid, and means ( ) for increasing the flow rate of said combined flow. Means for achieving a washing action at the signal generating portion are provided.
