Product Description

Nuclear magnetic resonance (NMR) spectroscopy provides qualitative structural information about the type, number, existing form, connection mode and relative orientation of atoms in molecules through the spectra of different nuclei, chemical shift values, peak multiplicity, coupling constant values, peak relative strength and correlation peaks in various two-dimensional and multi-dimensional spectra.The quantitative analysis of NMR is based on the structure analysis. The relationship between the number of protons of specific groups and the peak area of corresponding peaks is used for quantitative determination. Nuclear magnetic resonance (NMR) spectroscopy is mainly used to determine the structures of small molecules of organic compounds and biomacromolecules in solution. It is widely used in chemistry, biology, physics, materials, pharmacy and medicineThe superconducting magnet is immersed in liquid helium, and the outer layer of liquid helium is liquid nitrogen. The function of liquid helium is to maintain the superconductivity of the magnet to provide the required magnetic field environment. The purpose of liquid nitrogen is to add a "insulating layer" between the liquid helium and the external environment to reduce the volatilization of liquid helium.

(1) Rapidly freezing and transporting food, or making ice products;

(2) Research on low temperature physics;

(3) Demonstrate the low temperature state in science education. At room temperature, a soft object soaked in liquid nitrogen will be as brittle as glass;

(4) Provides the temperature required for high temperature superconductors to show superconductivity.

(5) It can be used as refrigerant to quickly freeze biological tissue to prevent tissue damage.

(6) It is used for industrial nitrogenous fertilizer.

(7) For chemical detection.

Liquid nitrogen is a liquid with a low temperature of - 196 ºC and is obtained from nitrogen which occupies more than 70% of the air. Inert, colorless, non-toxic, volatile, very wide range of use. Liquid nitrogen is easy to volatilize at low temperature, so it is generally stored in a special container liquid nitrogen tank.

According to the use of liquid nitrogen purity classification, often divided into food grade liquid nitrogen, industrial grade liquid nitrogen. The purity of food grade liquid nitrogen is high, because considering the safety of human consumption, the purity reaches 5 9, that is 99.999%. The purity of industrial grade liquid nitrogen is not as high as that of food grade liquid nitrogen.

In the process of using liquid nitrogen, people often think that the safety is not good, but because of the low temperature of liquid nitrogen, it will gasify immediately when it meets air, so the safety is still guaranteed. Just pay a little attention to safety, and there should be safety awareness in any case. Performance requirements
