When HPLC stops responding: a guide to understanding (and solving) common problems
However advanced current HPLC systems may be, all of us who work in the lab know that problems can arise at any time. An unstable baseline, a peak that doesn't appear, a pressure that rises without warning… What should be a routine analysis suddenly becomes a diagnostic exercise.
Even the most robust methods, the best-designed columns , and the purest solvents are not immune to minor discrepancies that ultimately affect system performance. Sometimes the source of the problem is obvious. Other times, however, it requires a more expert and meticulous examination.
This guide offers a practical and clear approach to detecting, interpreting, and resolving the most common errors in liquid chromatography. More than just a list of symptoms, we want to help you understand what's happening in the system when something stops working as it should. Because anticipating errors—and recognizing the signs early—not only saves time and resources, but also ensures the reliability of your results.
