Optical analytical device, waveguide and method

摘要: A device for detecting a first material comprising (a) waveguide having on peripheral surface of the second which contacting selectively combines with to measurably change light transmitting capabilities waveguide, (b) source positioned transmit into and (c) means measuring exiting from waveguide. The described in previous sentence is new article manufacture. useful method steps exposing an unknown may contain material, upon being contacted by waveguide; through after exposure step (a); and, transmitted as measure material. can be used either qualitative or quantitative analysis.
