Magnetic particles for the separation and purification

2006/10/25Nucleic acid separation is an increasingly important tool for molecular biology. Before modern technologies could be used, nucleic acid separation had been a time- and work-consuming process based on several extraction and centrifugation steps, often limited by small yields and low purities of the separation products, and not suited for automation and up-scaling. During the last few

International Conference on Ionic Liquids in Separation

The aim of the Fifth International Conference on Ionic Liquids in Separation and Purification Technology is to provide a forum for researchers in academia, national laboratories, and industry to share and discuss their latest results on the use of ionic liquids in separation applications.

Separation and purification processes play a critical role in biorefineries and their optimal selection, design and operation to maximise product yields and improve overall process efficiency. Separations and purifications are necessary for upstream processes as well as in maximising and improving product recovery in downstream processes. These processes account for a significant fraction of
