Abstract: The invention relates to an electromagnetically actuatable gas valve for metering a gaseous fuel into a suction tract of a motor, in particular a gas or diesel gas motor, comprising a valve seat (1) which is designed as a flat seat and which has multiple annular webs (3) that are arranged in a concentric manner and are connected via at least one radially running web (4) in order to delimit circular or semicircular through-flow openings (2). The electromagnetically actuatable gas valve further comprises a movable valve plate (5) which sealingly interacts with the valve seat (1) and which has multiple annular sealing webs (6) that are arranged in a concentric manner and can be brought into an overlapping arrangement with the circular or semicircular through-flow openings (2) of the valve seat (1).

Abstract: The invention relates to a method for continuously determining the concentration of at least one CN compound in an aqueous solution, wherein a carrier gas, for example compressed air, is introduced into the aqueous solution and the introduced carrier gas is fed at least partially to a gas analyzer, for example an HCN gas analyzer, the analysis data of which are considered in the determination of the concentration of the CN compound in the aqueous solution. In order to create advantageous method conditions, the temperature of the aqueous solution exposed to carrier gas is considered in the determination of the concentration of the CN compound.
