The unit uses advanced, high-stability mirrors and filters designed for longevity, which the manual describes for proper calibration. 3. Operation and Method Development
Connect the tubing coming from the column outlet directly to the bottom port of the flow cell. Use the standard PEEK or stainless steel finger-tight fittings.
The display should indicate "D2" when the lamp is operational. C. Flow Cell Maintenance and Cleaning
details several advanced features that differentiate it from standard detectors: Temperature-Controlled Flow Cell
Do you need for a specific task like dual-wavelength mode?
Enables simultaneous monitoring of two different wavelengths. 2. Safety Precautions and Installation Before operating the
Use the arrow keys to enter your target wavelength (e.g., 254 nm). Press to confirm. Step 3: Purging and Zeroing
The SPD-20A can monitor two wavelengths simultaneously. Note that using dual-wavelength mode slightly increases baseline noise compared to single-wavelength operation.
: This message indicates that the deuterium lamp failed to ignite after several attempts. Causes : A D2 lamp that has reached the end of its life is the most common cause. However, a defective PCB (circuit board) can also be responsible. Solution : Start by installing a new D2 lamp and resetting its usage time. If the error persists, contact a service engineer.
