Abstract

A system for monitoring a composition includes: an electromagnetic source that emits a beam; one or more evanescent field sensing element inside a tubular structure, arranged in series along a flow direction of the composition, and configured to be in direct contact with the composition; a waveguide that directs at least a portion of the beam to the evanescent field sensing element as an incident beam; and a detector configured to obtain a spectral distribution of the fingerprint beam. The evanescent field sensing element provides partial or total internal reflection of the incident beam at an interface between the evanescent field sensing element and the composition, and the incident beam interacts with the composition to form a fingerprint beam.
