In the middle and bottom rows quot 20 mM quot is interpreted as the sodium dihydrogen phosphate concentration The mobile phase was prepared by adding
So I was wondering if there are any chemicals that can replace dihydrogen ammonium phosphate as the mobile phase Thanks in advance
Measuring the pH of the mobile phase after the organic has been added E g sodium phosphate buffers should be adjusted with only phosphoric acid or
Dear all today I faced a problem while making mobile phase and the composition phosphate 15g Di sodium hydrogen phosphate 15g in 1000ml water
