Multichannel optical switch for in-line spectroscopic compound analysis

A detection system, comprising:

• at least one reference optical flow cell configured to continuously receive a reference fluid;
• at least one sample optical flow cell configured to continuously receive a sample;
• a single electromagnetic radiation (EMR) source, wherein the single EMR source is collimated;
• a multichannel optical switch configured to receive the EMR from the single EMR source, the multichannel optical switch comprising a fiber optic switch configured to generate a plurality of EMR beams from the single EMR source, wherein each EMR beam is configured to pass through one of the at least one reference optical flow cell or one of the at least one sample optical flow cell, and wherein each of the at least one reference optical flow cell and the at least one sample optical flow cell comprise at least one optical interface coupler configured to create a discrete optical path orthogonal to the reference fluid or sample fluid;
• a plurality of detectors, each one of the plurality of detectors is configured to receive EMR passed through one of the at least one reference optical flow cell or one of the at least one sample optical flow cell;
• and
• a controller operably coupled with the plurality of detectors and configured to continuously detect a property of the sample in one of the at least one optical flow cell with respect to the at least one reference optical flow cell.
