ABSTRACT:
A method and apparatus provide a system for measuring a measurable component in a sample. A sample is introduced into a chamber. A permeable membrane to the measurable component allows the component to pass into a second chamber. In the second chamber the component is measured directly or reacted in the presence of an enzyme to generate a detectable product detected by a detector therein. The second chamber is then flushed. The second chamber is only of a size sufficient to contain enough liquid to wet the detector therein.
