Dear everyone, Does somebody know the right content of Potassium Phosphate Buffer ? Is it a solution of Dipotassium hidrogen phosphate (K2HPO4), Potassium dihidrogen phosphate (KH2PO4), or Potassium phosphate tribasic (K3PO4) ? Or a mixture of those component ? Thank you, Delvac Oceandy Eijkman Institute Jakarta Indonesia
