DEGASi® NG
Preparative series
Powerful degassers for the highest flow rates
The DEGASi® NG Preparative series contains the most powerful stand-alone inline degassers built for the highest flow rate requirements. Degasser models in this series are suitable for high-throughput applications, including preparative HPLC, flash chromatography, dissolution testing, clinical chemistry analysers, dispensing applications, and ink degassing.

Description
Models in the DEGASi® NG Preparative series can be configured with 1, 2 or 4 channels, depending on model, for a wide variety of applications requiring degasification of aqueous and organic liquids at flow rates up to 100 or even 1000 mL/min. The DEAGSi® Prep NG degasser is suitable for aqueous and organic solvents at flow rates up to 15 mL/min. The different variants of DEGASi® Prep+ NG are the most powerful degassers for organic solvents and can be configured for tubing sizes of 1/8″, 3/16″, or 1/4″ OD. The DEGASi® Prep+ AUX NG has identical properties to the other DEGASi® Prep+ NG units, but comes equipped with an additional channel for degassing of a parallel auxiliary liquid flow in the analytical range. The DEGASi® HighFlow 1000 NG can manage flow rates up to 1 L/min but is limited to water-based liquids.
Most DEGASi® NG Preparative series degassers remove dissolved gases by continuous inline degassing using a constant vacuum applied over a Systec™ AF membrane that is permeable to gases but not liquids. The exception is DEGASi® HighFlow 1000 NG which operates according to the same principle, but instead is based on a silicon membrane. The removal of dissolved gases from liquid chromatography mobile phases reduces retention time shifts and improves baseline stability, while also reducing the level of oxygen which otherwise can interfere with detection techniques such as UV absorption and fluorescence. All problems with bubbles are typically eliminated when 50% of the dissolves gases are removed, which often can be critical in analytical systems as well as dispensing applications.
Designed for every application
