Method for dosing a target component

A method for dosing a target component (20), the method comprising:

• dosing the target component (20), using a dosing system (10), to a target value (Z20) that corresponds to a desired nominal value (S20soll),
• thereafter, calculating a target value (Z21) of at least one further component (21, 22, 23) for after-dosing that is lower than a desired nominal value (S21soll) of the at least one further component (21, 22, 23) for after-dosing,
• thereafter, dosing the at least one further component (21, 22, 23) for after-dosing to the target value (Z21) of the at least one further component (21, 22, 23) for after-dosing,
• thereafter, determining an actual value (G20ist) of the target component (20) and at least one actual value (G21ist) of the at least one further component (21, 22, 23) for after-dosing,
• thereafter, calculating a content (A) of the target component (20) based on the actual value (G20ist) of the target component (20) and/or the actual value (G21ist) of the at least one further component (21, 22, 23) for after-dosing,
• thereafter, comparing the content (A) to a limit value (T) or to a tolerance band (T),
• thereafter, determining that the limit value (T) or the tolerance band (T) is exceeded, and
• thereafter, again dosing the at least one further component (21, 22, 23) for after-dosing.
