Technical Articles for Nitrogen Purge

product manual:
The main application fields of this product ★ Pesticide analysis: such as vegetables, fruits, grains, plant tissues ★ Environmental analysis: such as drinking water, groundwater and polluted water samples ★ Biological analysis: such as hormone analysis, liquid phase, gas phase and mass spectrometry analysis Sample preparation ★ Food and beverage: such as milk, wine, beer, etc. ★ Pharmaceutical drug testing: such as traditional Chinese medicine, drug screening main features
1. The heater enables the sample to be quickly and efficiently heated to the evaporation temperature, and at the same time the gas is blown from the gas chamber to the surface of the solution through the gas needle to promote rapid solution evaporation and sample concentration
2. Each purge needle can be controlled independently and can be purged independently without wasting gas
3. The whole working system consists of adjustable gas chamber and heater
4. The position of the gas needle in the gas chamber can be changed to make it suitable for different test tubes. The standard gas needle length is 150mm
5. The height of the air cavity can be adjusted according to the height of the liquid level of the solvent. When concentrating toxic solvents, the entire system can be placed in a fume hood
6. Automatic fault detection and alarm function
7. Standard equipped with air cavity and special adjustable bracket
8. Built-in over-temperature protection device
9. Instant temperature display, decreasing time display technical parameters:
