Method and apparatus for controlled production of a fluid reaction product

A method of producing a chemical compound, by use of a device comprising:

• a reaction chamber;
• one or more fluid connections extending from an exterior of said reaction chamber and opening into said reaction chamber to introduce fluidic component(s) into the reaction chamber;
• a reception chamber;
• an activatable fluid transfer device providing a fluid connection between the reaction chamber and the reception chamber so that the reception chamber receives a fluid product produced in the reaction chamber when the fluid activatable fluid transfer device is activated;
• an activatable discharge connection for discharging fluid product from the reception chamber;
• a control unit configured to control the flow of fluid into the reaction chamber through said one or more fluid connections;
• a first amount sensor arranged to determine the amount of fluidic component(s) of the reaction chamber continuously or at least quasi-continuously at least during the introduction of fluidic component(s), wherein the first amount sensor is operatively coupled to the control unit to communicate to the control unit by a sensor readout of the determined amount in the reaction chamber;
• a second amount sensor arranged to determine the amount of fluid product in the reception chamber continuously or at least quasicontinuously, wherein the second amount sensor is operatively coupled to the control unit to communicate to the control unit by a sensor readout of the determined amount of fluid product in the reception chamber, the method comprising:
• determining a minimum threshold amount of fluid product to be present in the reception chamber;
• determining on the basis of readouts from the second amount sensor the amount of fluid product present in the reception chamber;
• a) introducing a selected fluidic component into the reaction chamber through one of the fluid connection(s),
• b) determining on the basis of readouts from the first amount sensor the total amount of fluidic component in the reaction chamber and continuing steps a) and b) until the total amount of fluidic component introduced has reached a prescribed total amount of the fluidic component, and
• c) repeating steps a) and b) until all the required selected fluidic components have been introduced into the reaction chamber if the amount of fluid product present in the reception chamber is below the determined minimum threshold amount, wherein the minimum threshold amount is determined on the basis of historical time series of data comprising discharge amount as a function of time.
