Patent ID: 7359060

Claim:
A spectrometric method comprising: a. inserting a probe within a fluid sample medium, the probe having a probe outer surface including a cavity, wherein the fluid sample medium flows into the cavity when the probe is inserted into the fluid sample medium; b. emitting light from the probe at two or more emission locations, wherein at least a portion of the emitted light is emitted into the cavity, and each of the emission locations emits light having a different mean wavelength; c. collecting light from at least two collection locations on the probe outer surface, the collected light including at least two of the following types: (1) light transmitted through the fluid sample medium, the transmitted light being emitted from an emission location at one side of the cavity and collected from a collection location at an opposing side of the cavity; (2) light transflected through the fluid sample medium, the transflected light being emitted from an emission location at one side of the cavity and reflected from an opposite side of the cavity; and (3) reflected light from the fluid sample medium, the reflected light not being emitted or reflected from any side of the cavity opposite any location from which the reflected light was originally emitted.
