Abstract
A gas analysis system (1) includes an inflow portion (C1) into which sample gas flows, a column (41, 42), a detector (50, 51) that detects a component in sample gas, a sampler module (M1) and a switching module (M2) including a plurality of valves (V1 to V10), and a controller (100) that independently controls the plurality of valves (V1 to V10). The controller (100) includes a storage (120) where function pattern information that defines correspondence between a plurality of basic functions and opening and closing patterns of the plurality of valves is stored and an output unit (110) that uses the function pattern information stored in the storage (120) to output control signals to the respective valves (V1 to V10).
Claims6
A gas analysis system comprising:
- a separator that separates sample gas into one or more gas components;
- a detector that detects the gas components that flow out of the separator;
- a flow channel fluidly connected to the separator and the detector;
- a plurality of valves provided on the flow channel, the plurality of valves being controllable independently of one another;
- and
- a controller that independently controls the plurality of valves, wherein
- the plurality of valves have such an arrangement that a flow channel pattern is changeable between a first flow channel pattern and a second flow channel pattern in accordance with a controlled state for each of the plurality of valves,
- the controller includes
- a storage where information on the controlled state for each of the plurality of valves corresponding to the first flow channel pattern and the second flow channel pattern is stored, and
- an output unit that generates signals for controlling the plurality of valves based on the information stored in the storage and outputs the signals to the plurality of valves, and
- the information stored in the storage includes information that defines correspondence between a plurality of functions different in purpose from one another and the controlled state of the plurality of valves.
