I selected this column because this column retains well 4-aminophenol under typical RP conditions without IP reagent but most others do not. My method works just fine except the column died (peak splitting) at 150 injections (method with 20 min run time, 30 oC column temp)
My question is if it is possible to extend the column life time to 500 injections if I low pH to 5.5 ? Did anyone do some study about the relationship between pH and column life?
