Introduction: The ND100 series nitrogen purging instrument is a high-precision temperature control instrument formed by the combination of microcomputer processing and PID control. Its working principle is to rapidly, continuously and controlly blow nitrogen gas onto the surface of the heated sample according to the evaporation rate of the concentrated solvent. And boiling point, set the heating temperature to achieve rapid concentration of a large number of samples. The instrument adopts aluminum block heating module, which has good heat transfer and uniform heat transfer, which is convenient for rapid heating and rapid temperature control. Nitrogen gas is blown onto the surface of the sample to achieve anaerobic concentration of the liquid sample. The blowpipes are independent of each other and do not cause cross-contamination. Each gas needle channel on the gas distribution assembly can be used in combination or separately. The system has high temperature control precision, wide temperature control range, temperature digital display and convenient temperature calibration. The appearance of the product is beautiful and elegant, the operation is simple, and the use is safe and reliable. Application areas: 1. Analysis of pesticide residues: such as vegetables, fruits, grains, plant tissues 2. Environmental analysis: water, groundwater and polluted water samples 3. Biological analysis: sample preparation in hormonal analysis, liquid phase, gas phase and mass spectrometry 4. Food and beverage: such as milk, wine, beer, etc. 5.
