Adjustable flow nitrogen dryer (sample concentration device)Principle:

Using inert gas to blow the heated sample solution, the processed sample is rapidly concentrated, achieving the effect of rapid separation and purification. This method is easy to operate, especially for processing multiple samples simultaneously, greatly reducing the detection time. Widely used in pesticide residue detection, pharmaceutical industry, and general research for sample batch processing.

Main features:

Nitrogen is a gas that is not easily reactive with other substances. Drying with nitrogen can prevent chemical reactions between the gas and other substances that dissolve in water, resulting in precipitation. Drying with nitrogen gas increases gas flow and removes volatile water, thereby making the vessel dry and clean. Nitrogen is more cost-effective compared to other inert gases.
