I was shocked to find out that the single room air conditioner would cause Agilent 1260 HPLC VWD detector baseline fluctuation yesterday. I could not even believe it.
Every time I turned on the air conditioner, the baseline of a nearby HPLC (2 meter distance) shown a wave, even when I blocked the cool air flow from the AC to reach HPLC. The wave interval is about 10 minutes.
So the only possibility is the radiation emitted by AC cause HPLC VWD problem.
Do you have experienced or heard of this problem? What is the mechanism behind it?
