Detecting estrogens at trace concentrations in biological fluids is key to understanding their role in the induction - and treatment - of disease. Researchers from the University of Texas Arlington, USA, have developed a method using restricted access-media (RAM) that enables the detection of trace levels of estrogen's using LC–MS–MS without liquid–liquid extraction (LLE) or solid-phase extraction (SPE).
