Centrifuges - an overview ScienceDirect Topics

Centrifuges - an overview ScienceDirect Topics

Any attempt systematically to classify the different centrifuges, including gas centrifuges, arrives at the following main definition of the physical forces occurring in the centrifuge: gas separation, demulsification, sedimentation and filtration (Figure 1).Demulsification is the separation of a liquid mixture into two liquid phases with different densities, which also mutually emulsify.

Mar 15, 2012 Specifically, that recovery for AEA, 1-AG, and 2-AG (96%, n = 3) was within-assay precision for 2-AG (5.4%, n = 3). Since 1-AG and 2-AG undergo rapid isomerization, it is difficult to report quantities of each species originating from tissues with certainty ( 9 ), thus results are reported as the sum of the individual peaks of 2-AG + 1-AG.
