RI detector

[ebasarah]

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!

What's your EG concentration - you may be overloaded.

1 % EG in ACN ; 5 microL injection

Yes, I'd dilute.
