A method and an apparatus determine a content of a foreign gas in a process liquid in which a measurement gas, especially CO.sub.2, has been dissolved. A concentration of the measurement gas is ascertained and a concentration of the gas mixture formed by the measurement gas and the foreign gas is ascertained, especially via a manometric measurement method. The measurement values are supplied to an evaluation unit. A concentration of the foreign gas is determined on the basis of the ascertained concentration of the measurement gas and the ascertained concentration of the gas mixture.

A fluid detection sensor includes: an optical sensor including a light emitting element array and a light receiving element array which are arranged on a substrate along a longitudinal direction thereof; a flow path member which includes a tubular body which is transparent and is arranged along the longitudinal direction facing the optical sensor, an inside of the tubular body constituting a flow path through which a plurality of substantially immiscible fluids flow as a slug flow; and a reflecting member placed on a side opposite to the optical sensor with respect to the flow path. The fluid detection sensor detects changes in light which occur in accordance with a movement of the plurality of fluids by the light receiving element array receiving light which is emitted by the light emitting element array toward the slug flow in the flow path and is reflected by the reflecting member.
