I need to analyze Hydroquinone in phenol.
What chromatography is recommended?
GC or HPLC?
Which conditions?
Thank you in advance
At 10% level? 10 ppm level?

From the structure of hydroquinone, likely either HPLC or GC could do the task. I'd likely start with HPLC, reverse phase and UV detector.

If I was doing by GC, I'd likely do trimethylsilyl derivatization to make the OH groups more stable.
100 ppm level
I'd try HPLC first.
