WebNov 19, 2014 · 1) An unbuffered acid tends to be a chaotrope, and chaotropes antagonize retention in HILIC. If you're at a pH above the pKa of the anion (3.75 for formate and 4.75 for acetate), then this won't be an issue. If you're at a pH well below the pKa, then a lot of the anion will be in the unbuffered acid form. 2) The pH also affects the charge of an ... WebDec 1, 2010 · From these observations, we propose a mechanism in which hydrogen transfer from coordinated formate anion to zerovalent palladium (NHC) (MA) (alkyne)-complex is followed by migratory insertion of hydride, after which the product alkene is liberated by proton transfer from the triethylammonium cation. The explanation for the high selectivity …

WebWe conclude that the combination of HPLC with RIA ensures the specific measurement of the ANG II cascade family members while non-chromatographic processing of tissue renders ANG II measurement non-specific. In addition, the use of triethylammonium formate as mobile phase additive is superior in the HPLC separation of the angiotensins.
