Focus of the MonthBiotech Fluidics Inline Degassers

The Biotech Fluidics DEGASi series of online vacuum degassers ensure efficient degassing of flowing liquids under a variety of conditions. Designed for different solvents and a wide range of flow rates, there is always a model that suits your needs for an efficient degassing process.

 

What are the traditional methods of bubble removal?

 

Traditional methods to remove bubbles and dissolved gases from liquid chromatography mobile phases are debubbling and ultrasonication. The problem is that neither of these approaches are particularly efficient.

 

Debubbling removes only the gases that have outgassed into visible bubbles. Since this approach does not address the root cause of bubble formation, the remaining dissolved gases will likely form bubbles again and cause issues with precision in the liquid handling system. Ultrasonication typically removes about one third of the dissolved gases, and while this may reduce the tendency of bubble formation, it is often not sufficient to entirely prevent formation of bubbles.

 

Why Inline degassing?

 

Gases dissolved in liquids often cause troubles in fluidic systems. The gas molecules can form bubbles when pressure or temperature changes, and this will affect the accuracy, precision and performance of the equipment.

 

Inline degassing efficiently removes dissolved gases from the fluid stream and thereby prevents bubble formation, reduces noise, improves baseline stability, reduces startup times and ensures more consistent results. This is very important in laboratory analysis equipment such as liquid chromatography, HPLC, UHPLC, ion chromatography and mass spectrometry.

 

Efficient degassing requires high-quality components. The DEGASi® family of degassers are based on patented, cutting-edge vacuum pump and regulation technology, combined with highly efficient Systec™ AF gas-permeable membranes.
