In the course of the experiment, we will encounter that the user reacts to the deuterium lamp is noisy, but we are not sure which problem has occurred. This situation has the following reasons, which may cause the deuterium lamp to be noisy.
1. Whether the deuterium lamp has reached the service life, the energy of the deuterium lamp is reduced, and the requirements cannot be met
2. Whether the flow cell or the flow cell window is clean, even a few pollutants will generate noise. (The dirty flow cell is also related to the energy of the deuterium lamp)
3. Is it the ultrapure water just prepared?
4. Is the mobile phase degassing good?
5. Are there bubbles in the system
6. Make sure the pre-column pressure is stable and see if the mobile phase is used correctly
7. Whether the chromatographic column has been used for a long time (possibly the column packing is collapsed, lost or blocked), it is best not to connect the column.
8. Whether the related signal circuit is abnormal, causing this phenomenon
9. Check for bubbles in the detector
