Flush the flow cell with a mobile phase that is transparent at your target wavelength.

The SPD-20A can monitor two wavelengths simultaneously. Note that using dual-wavelength mode slightly increases baseline noise compared to single-wavelength operation.

The is a high-performance ultraviolet-visible (UV-Vis) absorbance detector widely utilized in High-Performance Liquid Chromatography (HPLC) systems . Renowned for its exceptional sensitivity, low noise levels, and long-term stability, this dual-wavelength detector is a staple in pharmaceutical, environmental, and academic research laboratories.
