gold extraction by centrifugal methods

Why Centrifugal Partition Chromatography is a Better Way

The technique also saves time by requiring only one 30-minute step after the crude cannabis extract is injected into a CPC column. Use of CPC for CBD extraction. Like HPLC, CPC uses a stationary phase and a mobile phase. While both methods share the same underlying biochemical principles, they differ in the nature of the stationary phase. Get price
