THIN-FILM BIO-SENSOR, AND METHOD OF OPERATING SAME

摘要

Apparatus (10) for determining the presence of a conditioning film as a precursor indicator to bio-contamination of fluid, includes: a substream (14) having an optically-reflective surface (16); a body (11) having a flow passage (18) for said fluid and having an optical passage (19), the optically-reflective substratum surface being arranged in said flow and optical passages, the body having two windows (20, 21) arranged perpendicularly to the axis of said optical passage; and means (22) for determining the presence of said conditioning film on said optically-reflective surface.
