This image represents baseline drift in HPLC (High-Performance Liquid Chromatography), where irregular peaks and fluctuations in the baseline impact data stability. Baseline drift can obscure low-intensity peaks, affecting the reliability of HPLC results. The article provides troubleshooting steps to address common causes like solvent quality, air bubbles, and equipment issues, enhancing chromatographic accuracy.
