Hi Richard

Thank you.

mobile phases: A: 10 mM of phosphate solution buffered at

pH 2.70 with concentrated sulphuric acid; B: 100%

acetonitrile.

David Salehi

Oxalic acid and Propionic Acid are hydrophilic, so make sure your column is for hydrophilic compounds. I have BioBasic™ AX HPLC Columns. I hope it helps.
