My question is as follows...Hoping for some advice. I am working on a remediation project for an API manufacturing company in europe where part of their manufacturing process involves large scale column chromatography using silica gel.
The company at present does not test each batch post chromatography i.e. the product cut.....but runs the product cut from each column (based on known times when product comes off on the column) to a common holding tank....Maybe 2-3 columns are run a day. The holding tank where all of the 'good' product' goes post chromatography is tested each day...i.e a composite that is being topped up daily.....
Aware of the guidelines around blending potential in-spec and potential out of spec batches and the issues around that....Just wondering if there is any guidance / advice out there on this distinct area.
Thanks,
