Abstract
An apparatus and method of use are provided; the apparatus having at least a degasser, a hollow core fiber HCF, an optical mechanism, a detector, and circuitry. The degasser enables gasses to permeate out of a liquid into the degasser interior. The propagator establishes a low-pressure area that helps to pull the gas from the degasser interior into the HCF interior, where the optical mechanism delivers electromagnetic radiation EMR that interacts with the gas. The detector determines EMR absorption, producing output signals which are sent to the circuitry. Circuitry controls the optical mechanism and analyzes the output signals to quantify the concentration of gas in the HCF and in the liquid.
