Tetrabutyl ammonium hydrogen sulfate TBAHS

Procedure (See Chromatography, Appendix IIA.) Use a high-performance liquid chromatograph capable of separating acesulfame potassium and 4-hydroxybenzoic acid ethyl ester with a resolution of 2. Use a chromatograph equipped with a UV or diode array (227 nm) detector and a 25-cm x 4.6-mm (id) stainless steel column, or equivalent, packed with 3 to 5 p,m of reversed phase C18 silica gel, or equivalent. The elution is isocratic. Use a 40 60 (v/v) solution of acetoni-trile 0.01 MlL tetrabutyl ammonium hydrogen sulfate (TBAHS) in water as the mobile phase, with a flow rate of about 1 mL/min.
