RI detector

Hello Guys,

I need advice from someone who has good experience with R.I Detector to help me solve this problem.

I tried to detect ethylene glycol with R.I but the peak was broad( rectangular shape...flat on the top) and showing both positive and negative peaks.

What is the problem?

Thanks again!
