provides advanced procedures for adjusting optical filters and mirrors, though it explicitly cautions that prior training is recommended. The flow cell is critical for baseline stability
The SPD-20A is designed for high-sensitivity analysis, featuring a noise level as low as and a wide linearity range up to 2.5 AU . SPD-20A Specification Light Source Deuterium (D2) Lamp Wavelength Range 190 to 700 nm Wavelength Accuracy ± 1 nm max Bandwidth Operating Temp 4°C to 35°C 2. Quick Start and Daily Operation
Your detector tracks its own health, but you need to track yours. Don't just read the manual; use it to build a small to track over time:
If you are analyzing compounds that absorb at vastly different wavelengths, utilize the program function to switch wavelengths during the run to maximize sensitivity for each component. 3. Advanced Troubleshooting: Solving Common Issues
