A flow cell for measuring electromagnetic radiation absorption spectra in a continuously flowing immiscible liquid(s) or liquids with entrained gas phases

摘要

An apparatus and method for spectral analysis of immiscible phases are disclosed. A flow cell for online absorption measurements of immiscible process phases can comprise: a body containing an inlet window and an outlet window in operable communication with a measurement instrument; and a series of partitions that divide the inside of the flow cell into three (3) or more vessels that have an inlet and an outlet wherein the vessels are connected in series with one another. Optionally the first vessel is equipped with a porous membrane to facilitate the separation of immiscible process phases.
