: The unit uses a low-pressure mercury lamp for automatic wavelength accuracy checks. International Equipment Trading Ltd. For digital copies, you can often find the SPD-20A Instruction Manual Service Manual on platforms like Scribd. or a guide for replacing the D2 lamp
Avoid touching the glass bulb of the new lamp with bare fingers (skin oils cause hot-spots and premature cracking). Use lint-free gloves. Align the locating pin, insert the lamp, and tighten the screws.
Regular maintenance extends the life of your detector and ensures data integrity. shimadzu spd20a user manual
It offers a wide linearity of up to 2.5 AU, enabling accurate quantification across a broad concentration range.
The Shimadzu SPD-20A is a high-sensitivity UV-VIS detector for the Prominence HPLC series, featuring a temperature-controlled flow cell to minimize baseline drift in the 190 to 700 nm range. Key features include dual-wavelength monitoring, 2.5 AU linearity, and automated wavelength scanning for improved analytical performance. Maintenance includes regular lamp energy monitoring and flow cell cleaning. For detailed operating instructions, refer to the Shimadzu manual .

lamp typically provides reliable performance for approximately 2,000 hours of use. Replace the lamp when energy levels drop below acceptable thresholds or when baseline noise becomes intolerable. or a guide for replacing the D2 lamp
The SPD-20AV model allows both deuterium and tungsten lamps to be lit simultaneously, allowing for high-sensitivity wavelength programming across UV and visible light ranges.
Ensure instrument is away from drafts. Flush the flow cell with 0.1M Nitric Acid, followed by copious amounts of water. Contaminated flow cell or column bleed.
