Occurs when the absorbance is outside the detector's range (too high or low), or if the baseline has not been zeroed. High Noise/Baseline Drift: Thoroughly degas the mobile phase. Check for lamp energy degradation. Flush the flow lines.
The is a high-performance UV-VIS detector widely used in High-Performance Liquid Chromatography (HPLC) for its exceptional sensitivity and reliability. This guide serves as a "better" manual, focusing on practical setup, performance optimization, and maintenance beyond the standard technical documentation. 1.
