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 ( 26, 30, 32 ), a sampling device ( 4 ) for providing a sample of said biological fluid, and means ( 10, 15, 18, 24 ) for passing a flow of a background fluid through said flow passage at selectable flow rates, means ( 20, 50, 55 ) for injecting said sample into said flow of background fluid, and means ( 50, 55 ) for increasing the flow rate of said combined flow. Means for achieving a washing action at the signal generating portion are provided.
