I cannot select a method to start a new Control Chart, what is the problem?
Before starting a new Control Chart with a new batch, you must add new batch limits.
The Average and Standard deviation values can be found in the Certificate of Analysis.
If you use a method not listed on the Certificate of Analysis, choose a value of the method with the same target organism as your method.
More information you can find at Batch limits • BiosistoStandard
