An unexpected retention order for ketamine analogs was observed when using a biphenyl stationary phase for liquid chromatography-mass spectrometry (LC–MS).

In electromembrane extraction (EME), the target analyte is extracted from an aqueous sample across a supported liquid membrane (SLM) and analyzed using LC. Through the study presented here, we demonstrate the principles of the technique and test its performance.
