Device for extracting gaseous and liquid products from a reaction fluid

A device for extracting gaseous and liquid products from a reaction fluid, in particular from an electrochemical reaction systems, comprising

• at least one inlet for a flow of a reaction fluid comprising dissolved gaseous reaction products and liquid reaction products to be analyzed into the device,
• at least one outlet for a flow of a fluid depleted of said gaseous reaction products and liquid reaction products out of the device;
• at least two compartments, wherein
• a first compartment is configured for separating the gaseous reaction products from the reaction fluid using a first membrane supported on a porous material, and
• a second compartment is configured for subsequently separating the liquid reaction products from the reaction fluid using a second membrane supported on a porous material,
• wherein the first and the second compartment are connected by an extended capillary tube system,
• wherein the capillary tube system is configured to guide the reaction fluid from the inlet into the first compartment for contacting the first membrane for separating the gaseous reaction product from the reaction fluid and subsequently into the second compartment for contacting the second compartment for separating the liquid reaction product from the reaction fluid;
• wherein each of the at least two compartments is connected to a corresponding vacuum source for applying a vacuum to the first and second membrane, respectively, for transferring the flux of gaseous reaction products and liquid reaction products through the corresponding first or second membrane into the vacuum for further analysis, in particular MS analysis.
