The SPD-20A is designed for high-sensitivity detection in the UV range, while the SPD-20AV expands this capability into the visible spectrum.
Accesses validation and parameter customization menus.
The Shimadzu SPD-20A is one of the most reliable and widely used UV-Vis detectors in the HPLC (High-Performance Liquid Chromatography) market. Known for its low noise level and high sensitivity, it is a workhorse in quality control and research laboratories.

Furthermore, the is a parameter often overlooked by novice users but emphasized in the manual. This setting acts as an electronic filter to smooth out high-frequency noise. However, there is a trade-off: a longer response time reduces noise but can blur sharp, narrow peaks, reducing resolution. Conversely, a shorter response time preserves peak shape but increases baseline noise. The manual recommends a response time set to approximately 10% of the target peak’s width at half height.
Manuals provide standard operating procedures (SOPs) for daily use: Turn on the main power. For the , the display should show "D2" once the lamp is active.
