Imaging Analysis Ensures HPLC Column Performance

February 8, 2013 11:53 am | by Particulate Systems, Norcross, Ga.

If there was a method for packing material manufacturers to specify shape characteristics and for column manufacturers to inspect incoming materials against those specifications, manufacturing HPLC columns would become more predictable, less costly and exhibit consistent performance. Recent advancements in image analysis could provide the answer.
