Description

Description Manufacturing method for a gas analysis device, computer program product, gas analysis device, simulation method and simulation program product The invention relates to a method for producing a gas analysis device and to a computer program product designed to carry out the method. The invention also relates to a corresponding gas analysis device. Furthermore, the invention relates to a simulation method for such a gas analysis device and a corresponding simulation program product. Patent EP 2 828 653 B2 discloses a simulation of a chromatographic run on a chromatograph. The chromatographic run uses a mobile phase comprising a mixture of at least two eluent components with different chromatographic properties. Gas analysis devices are used in a wide variety of applications that require individual adaptation to meet requirements. Due to the physical and chemical complexity of gas analysis devices, appropriate adaptation is complex, time-consuming, and prone to errors. At the same time, cost-effective design of gas analysis devices is desired. There is a need to accelerate and simplify the manufacture of gas analysis devices, particularly application-specifically adapted gas analysis devices. The invention is based on the object of providing a possibility that offers an improvement in at least one of the aspects outlined. The object is achieved by a method according to the invention for producing a gas analysis device. The gas analysis device to be produced has at least one Separation device and a plurality of pneumatic modules. The separation device can, for example, be a separation column which, due to its filling and/or internal coating, is suitable for separating a substance sample into its components as it flows through. The pneumatic modules can, for example, be designed as pressure regulators, valves, throttles, detectors and/or lines. The pneumatic modules can differ in their physical design and/or in the control algorithms used therein. The method comprises a first step in which at least one target parameter for the gas analysis device to be manufactured is specified, for example by a user. The target parameter can be a technical variable of the gas analysis device, for example a separation performance parameter of the separation device or a maximum duration for the concentration analysis of a predeterminable substance sample. Alternatively or additionally, the target parameter can also be a non-technical variable, for example an energy requirement, a CO2 footprint or manufacturing costs. Furthermore, in the first step, a plurality of basic pneumatic assemblies is provided, each of which comprises virtual representations of the separation device and the pneumatic modules. The basic pneumatic assemblies can for this purpose be stored in a database, for example, and selected by the user and/or an artificial intelligence system. The basic pneumatic assemblies can be understood as the pneumatic counterpart to a circuit diagram and each specify a possible structure of a manufacturable gas analysis device. The basic pneumatic structures themselves are thus virtual representations of manufacturable gas analysis devices. The basic pneumatic structures represent a starting point for the further method steps. In addition, the claimed method comprises a second step in which a plurality of continuous and discrete parameters of the basic pneumatic structures are provided. For this purpose, the continuous and discrete parameters are identified as corresponding parameter types in the basic pneumatic structures and a compilation that contains these comprises, provided in machine-readable form. A continuous parameter can essentially assume any numerically possible value within a value spectrum. For example, a length of a line or a temperature of a material sample are continuous parameters. Likewise, coefficients that set a control algorithm of a pneumatic module are continuous parameters. A discrete parameter can only assume a limited number of predetermined values. A discrete parameter is, for example, information about a material used that is selected from a list of possible materials, or information about a design type of the detector used that is selected from a list of possible designs. The continuous and discrete parameters provided can therefore be distinguished from one another in their categorization as discrete or continuous by the second step. Furthermore, the second step involves determining a plurality of basic configurations based on the basic pneumatic assemblies. The basic configurations are determined by varying the discrete parameters in the basic pneumatic assemblies. Consequently, a plurality of basic configurations are determined for each basic pneumatic assemblie by varying, in particular systematically varying, the discrete parameters. The determined basic configurations are stored, at least temporarily, for further processing. The basic configurations thus correspond to basic pneu
