Nitrogen Blowing Concentrator (Pressure Blowing Concentrator) is abbreviated as Nitrogen Blowing Concentrator. It is used for sample preparation in liquid phase, gas phase and mass spectrometry analysis. It adopts internationally recognized technology, usually nitrogen is blown into the surface of the heated sample Concentration has the characteristics of time saving, convenient operation, easy control, etc., and can quickly obtain the expected results. Widely used in industries such as pesticide analysis, commodity inspection, food, environment, pharmaceuticals, biological products, etc. This technology uses solid phase extraction pretreatment technology to replace the traditional liquid phase extraction and chromatography technology, so that the sample can be quickly separated and purified. Nitrogen blowing is used to replace the commonly used rotary evaporator for concentration, which greatly shortens the analysis time.
Background of nitrogen purge instrument:
"MRSM" is an international advanced agricultural science and technology project organized by the Environmental Protection Institute of the Ministry of Agriculture and the Environmental Monitoring Station of the Ministry of Agriculture. The General Administration of Quality Supervision, Inspection and Quarantine of the People ’s Republic of China and the National Standardization Administration of the People ’s Republic of China also issued the “Testing Methods for Melamine in Raw Milk and Dairy Products†GB / T 22388-2008, which requires the use of a nitrogen dryer for milk Sample preparation of melamine in dairy products.
Main application fields of nitrogen purge instrument:
1. Pesticide analysis: such as vegetables, fruits, grains, plant tissues
2. Environmental analysis: such as drinking water, groundwater and polluted water samples
3. Biological analysis: such as sample preparation in hormone analysis, liquid phase, gas phase and mass spectrometry
4. Food and beverage: such as milk, wine, beer, etc.
5. Pharmaceutical drug testing: such as traditional Chinese medicine, drug screening
Main features of nitrogen purge instrument:
1. The heater enables the sample to be quickly and efficiently heated to the evaporation temperature, and the gas is blown from the gas chamber to the solution surface through the gas needle to promote the rapid solution
Evaporation and sample concentration
2. Each purge needle of the nitrogen purge instrument can be independently controlled 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. Nitrogen purge instrument has 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, time decreasing display
The main categories of nitrogen purge instrument:
1. According to the structure of the heating tank of the instrument, it is divided into: square and circumferential nitrogen blower
2. According to the heating method of the instrument, it is divided into: metal dry bath and water bath nitrogen blowing
