Troubleshooting Common HPLC Problems: Solutions for Better Results
HPLC troubleshooting doesn’t have to be overwhelming. Common issues like pressure fluctuations, baseline noise, and peak splitting can often be resolved with systematic diagnostics and simple adjustments. For pressure issues, regularly inspect filters, frits, and tubing, and ensure solvents are properly degassed. Baseline noise typically stems from mobile phase contamination or detector problems, which can be mitigated with clean solvents and proper flow cell maintenance. Peak splitting often points to column problems or solvent mismatches, which can be resolved by proper column installation and ensuring injection solvent compatibility.
