We had a ugly peak with LC-RID and I was wondering why.


sample is 100% water, and solvent is 100% water. I changed sample and solvent bottle water on the day I analyzed this.

Equilibrated the system for about 25 min. 


is this something the system is dirty? or because of the short equilibration time?


Thanks for your help!
