What is sample preparation / solvent evaporation?
In analytical or life science laboratories, the removal of solvents by evaporation is an essential step in sample preparation prior to chromatographic analysis.
Solvents can be evaporated by various methods. Gas flow evaporation using nitrogen is one of the most common evaporation techniques.
Chromalytic Nitrogen Generators support all evaporators from the most famous brands such as Biotage, Thermo Fisher Scientific, GERSTEL, Organomation and many more.
How does a nitrogen evaporator work?
The principle is based on the fact that gas is passed through a variable flow regulator and a heating element in the evaporator. The hot nitrogen then flows from needles located above the sample tube or plate and continuously blows hot air over the surface of the solvent. This evaporates the solvent quickly and gently. Ideal when a large number of samples need to be analysed.
The vaporiser requires a nitrogen supply to operate. Chromalytic gas generators provide a continuous source of nitrogen - ideal for sample preparation.
Sample evaporation requires a very large amount of nitrogen.
In times of high costs for bottled gas, our Chromalytic gas generators offer a cost-efficient and environmentally friendly alternative to conventional gas cylinders and ensure a continuous supply of nitrogen generated on site at all times. In addition, you can save yourself the handling and costs of ordering, storing and maintaining gas cylinders.
