1、 Introduction to nitrogen blowing concentration device:

1.Application of nitrogen blowing instrument

Used for sample preparation in liquid phase, gas phase, and mass spectrometry analysis. It adopts internationally recognized technology to concentrate the sample by blowing nitrogen into the surface of the heated sample. This method has the characteristics of time-saving, easy operation, and easy control, and can quickly obtain the expected results.

2.Adopting solid-phase extraction pretreatment technology instead of traditional liquid extraction and chromatography techniques enables rapid separation and purification of samples. Replacing the commonly used rotary evaporator with nitrogen blowing for concentration greatly shortens the analysis time.

3.The nitrogen blowing device uses water as the bathroom, which has good heat transfer, uniform heat transfer, and is conducive to rapid heating and temperature control. Blow nitrogen onto the surface of the sample to achieve anaerobic concentration of the liquid sample. Blow pipes are independent of each other and will not cause cross contamination.
