A component analysis device in a sample fluid includes an optical source, an optical detector that defines a beam path of the beam, and a beam path that defines an interrogation region in a fluid flow cell in which the optical beam interacts with the sample fluid and a reference fluid. A fluid flow cell disposed above and a scanning system that scans the beam for laminar flow within the fluid flow cell, the optical source emitting the beam, and the optical detector receiving the beam after partial absorption by the sample fluid. Measured, the sample fluid and the reference fluid are in laminar flow, and the scanning system causes the beam to scan against both the sample fluid and the reference fluid. |
