Abstract

The claimed invention relates to a control disc (10) for a gas analyzer (50) having a plurality of grooves (16), each of which has at least one fluid port (18), a first pair of fluid ports (21), and a second pair (22) of fluid ports (18). Each pair (21, 22) is designed to be sealable (closable) by a section of a diaphragm (30, 30.1, 30.2). According to the invention, the first pair (21) of fluid ports (18) is arranged radially offset from the second pair (22) of fluid ports (18). The invention also relates to a multi-port valve (40) for a gas analyzer (50) equipped with such a control disc (10). Furthermore, the invention relates to a corresponding gas analyzer (50).Furthermore, the invention relates to a method (100) for simulating the operating behavior of such a multi-port valve (40) and a computer program product (60) designed to carry out such a method (100).
