I am wondering if anyone has a similar problem with their RI detectors occasionally. This problem happened to me on a Shimadzu and Waters RI detector. I am grateful if anyone can give me some pointers. Thanks!
Problem:
The baseline drift down slowly and steadily, and then suddenly rise back to the starting level.

Condition: HPX-87H column, 60oC, 0.5mM H2SO4 0.6mL/min, Waters RI detector.
The mobile phase is properly degassed (sonicator + vacuum for about 1 hr)
