gamma-hydroxybutyric acid

UCT Clean Screen GHB Column Cited in Analytical Letters

May 24th, 2016

In this study into GHB analysis, which was published in Analytical Letters ((2016) 49:2 217–225) by Pyo et from College of Pharmacy, Kyungsung University, South Korea, solid-phase extraction (SPE)  was conducted using UCT’s Clean Screen GHB SPE columns (CSGHB). The recovery for gamma-hydroxybutyric acid by CSGHB was 64.5– 70.9% compared to 32.6–47.5% by liquid–liquid extraction. SPE using CSGHB also offered shorter analysis time, smaller sample quantities and solvent volumes, and better separation.
