Which type of column should i use to check the purity of high molecular weight protein using HPLC reverse phase column chromatography? Hi everyone. I wanna to check the purity of high molecular weight protein (collagen) with MW of ~130 kDa using a HPLC. I know C18
In BP2013, Loperamid HCl monograph. Assay by titration with 0.1N sodium hydroxide using hydrocloric acid 0.01N and reading the volume added between the 2 points of inflexion. I have a question that if the diluent solvent is ethanol is certainly consumed a amount of volume of titrant, so this volume must be eliminated on the result calculation or not apart from first point which is subtracted above.
