This guide breaks down the essential operations, maintenance, and advanced tips to help you master the SPD-20A and achieve superior chromatographic results. Key Specifications at a Glance 190 to 700 nm 190 to 900 nm Noise Level 0.5 x 10⁻⁵ AU 0.5 x 10⁻⁵ AU Linearity Up to 2.5 AU Up to 2.5 AU Light Sources Deuterium (D2) D2 + Tungsten (W) Dual Wavelength 1. Essential Startup & Operation

To ensure the longest possible life for your lamps and the most stable baseline, follow this refined startup sequence:
