4-Hydroxybutyrate besides Standard Anions and Organic Acids

4-Hydroxybutyric acid (GHB) is used as a psychoactive drug. In many jurisdictions, it is illegal. GHB can be determined by suppressed anion chromatography. On a Metrosep A Supp 16 - 250/4.0 column, GHB is separated from standard anions as well as from glycolate, formate, and acetate.
