HPLC Separation of Phosphorous and Phosphoric Acids

 

Application Notes: Phosphorus and phosphoric acid were separated on Obelisc N and Primesep D columns. On Obelisc N both acids retained by combination of HILIC and anion-exchange mechanisms. OnPrimesep D these inogranic acids are retained by anion-exchange mechanism. Both columns and methods can be used for analysis of hydrophilic organic and inorganic acids with multi-mode or single mode approach
Application Columns: Primesep D, Obelisc N
Application compounds: Phosphorous Acid, Phosphoric Acid
Detection technique: UV, LC/MS, ELSD/CAD
