- Sample energy is very low, but reference energy is good
- Washing the flow cell in 6N Nitirc acid does not resolve issue
- 2487 Dual Wavelength Absorbance Detector
Bubble in the flow cell.
FIX or WORKAROUND
- Flush unit in 100% methanol at 1 mL/min for 30 minutes.
- If flushing with 100% methanol does not work, replace the flow cell
