System for determining concentration of first fluid in second fluid in sample

Abstract

An optical sensing device for determining at least one property of a fluid. The device has an elongated porous body having a first end and a second end, a solid-state optical emitter at the first end of the body oriented to emit radiation toward the second end of the body, and a solid-state optical detector at the second end of the body oriented to detect radiation emitted by the optical emitter. A package for detecting properties of a fluid includes a body defining a cavity, with a movable and biased carrier for an optical detector or emitter mounted in the cavity for increased reliability. A system for determining relative concentrations of fluids in a sample includes emitter / detector pairs operating at reference wavelength and wavelengths corresponding to absorption peaks of at least two fluids, and a processor for determining concentration based on measured data and calibration data.

Problems solved by technology

[0007] However, the infrared spectral region is defined as a chemical entity in terms of material measurements, which is difficult to perform on used materials

More specifically, the optical components and associated materials used in these measuring devices are quite expensive and for large-scale production, these components and materials are not suitable for replicating

[0008] Furthermore, when multiple devices are used in one large monitoring system, for example, in automotive monitoring applications, these systems tend to become too large, complex and expensive
