is a cornerstone of modern high-performance liquid chromatography (HPLC). Its user and service manuals describe several high-end technical features that make it a frequent choice for sensitive research, such as the
Replace the flow cell windows if they become scratched. 5. Troubleshooting Common Issues Press FUNC to navigate to the wavelength screen,
The standard cell is designed for minimal dispersion and is temperature-controlled to prevent spectral drift.
Routine maintenance extends the lifetime of the optics and ensures data integrity. Deuterium ( D2cap D sub 2 ) Lamp Replacement SPD-20AV also includes W lamp (Vis) | |
Ensure a grounded, stable AC power source (100–240 V) to prevent electrical noise from corrupting your chromatograms. Fluidic Connections
