Thermo Fisher Scientific Dionex IonPac AS11-HC-4µm


Dionex IonPac AS11-HC-4µm

Achieve the optimal combination of chromatographic speed and resolution using the new Thermo Scientific Dionex IonPac AS11-HC-4µm anion-exchange column. This high-capacity, high-efficiency capillary column provides excellent resolution of a large number of organic acids and inorganic anions in complex sample matrices. Compared to the previous Dionex IonPac™ AS11-HC column, the new ion-exchange column uses smaller resin particles for more efficient separations resulting in more accurate peak integration and more reliable results. It has similar selectivity and increased peak efficiencies compared to the Dionex IonPac AS11-HC and was specifically designed to resolve a large number of inorganic anions and organic acids in a single run using a hydroxide gradient. Applications run on the Dionex IonPac AS11-HC column can be easily transferred to the Dionex IonPac AS11-HC-4µm column with the benefit of increased peak resolution, which provides more consistent results. The Dionex IonPac AS11-HC-4µm column is available in capillary format, 0.4 × 250 mm. The capillary format provides reduced eluent consumption, which helps reduce operating costs.
