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.

I'd try HPLC first.
