[A rapid separation and quantitation of sodium cyclamate in food by ion-pair reversed-phase high performance liquid chromatography].
A method of separation and quantitation of sodium cyclamate in foods by ion-pair reversed-phase high performance liquid chromatography is described. Sodium cyclamate can be separated on ODS column at room temperature by using a mobile phase of V(methanol):V(water, containing ion-pair reagent) = 30:70 at 1 mL/min flow rate. The effects of ion-pair reagent and methanol on the retention of sodium cyclamate were studied. The samples were quantified with an ultraviolet detector operated at 205 nm. The calibration curve was linear in the range of 0.50-2.50 g/L with a correlation coefficient of 0.9996. The recoveries were 96.9%-101.7%. The detection limit was 0.05 g/L. This method is simple, rapid and sensitive.
