The right choice…

DEGASi® GPC is the right choice of degasser if you are working with 100% organic solvents in your fluidic line. Some examples of application areas where this degasser is successfully used are GPC (Gel Permeation Chromatography) and Normal Phase Chromatography.

What’s unique

DEGASi® GPC uses the same 480 μl Systec AF™ degassing membrane as used in DEGASi® Classic. The main difference compared with the DEGASi® Classic is that we use a stented version of the vacuum chamber in the DEGASi® GPC.
The stent is a short piece of a stainless steel tube placed inside the ends of the degassing membrane. In order to make the internal ferrule in the bulkhead get a better grip. This solution makes an even more secure internal connection when working with 100% organic solvents in the fluidic line.

With the highly-permeable Systec AF™ membrane, an internal degasser chamber volume of only 480 μl is sufficient to give you excellent degassing efficiency up to flow rates of approximately 3 ml/min. The time the liquid spends inside the vacuum chamber is correlated to the degassing efficiency, so with a higher flow rate, the degassing efficiency will be lowered. In many cases, the 480 μl vacuum chamber can be used at 5 ml/min with sufficient degassing.
