Application


  • Separation of cresols using coelectroosmotic capillary electrophoresis.: This research explores the separation of cresol isomers using coelectroosmotic capillary electrophoresis. The study demonstrates an efficient method for analyzing cresol mixtures, which is valuable in both industrial and pharmaceutical applications where precise separation of isomers is critical (Masselter et al., 1993).

On-line hemodiafiltration (OL-HDF) with pre- as well as post-dilution reinfusion mode provides superior uremic toxin removal, especially middle uremic toxins, and can improve patient survival. Both standard pre- and post-dilution have limitations. Mid-dilution OL-HDF (Nephros OLpur) was invented to overcome
