Description
Technical field
The utility model belongs to storage container technical field, and in particular to the portable liquid nitrogen to a kind of single crystal diffractometer is mended
To device.
Background technique
X-ray diffraction technology is that people recognize one of most important approach and authoritative analysis method of material microstructure.?
In the case where not destroying sample, single crystal X-ray diffraction instrument measures the crystal structure of monocrystalline, can understand in Atomic Resolution level
The three-dimensional space of atom asks arrangement in crystal, obtains related bond distance, bond angle, torsional angle, molecular configuration and conformation, molecule asks interaction
And accumulation, a large amount of microscopic informations of molecular structure, absolute configuration and precise electronic density etc. simultaneously study its rule, thus further
The property of substance is illustrated, the development for subjects such as chemistry, physics, material science, life sciences provides basis.It can not overstate
It opens ground to say, awareness and understanding of the people for substance structure on atom, molecular level, most of X-ray for deriving from monocrystalline
Diffraction.Single crystal structure analysis has become people and recognizes indispensable most direct, most effective, the most authoritative side of material microstructure
One of method.
In the ancillary equipment of modern single crystal diffraction system, Cryo Equipment is worth mentioning.Crystal at low temperature, lattice
The thermal vibration of interior atom greatly reduces, and the diffracting power of crystal can greatly enhance, and obtains the crystal diffraction quality of data collected
Greatly improve.Especially to unstable sample under room temperature environment, its stability can be effectively improved at low temperature and
Conducive to its crystal structure determination work, decomposition of the crystal in test process, weathering iso-metamorphism can be solved the problems, such as.Cryo Equipment for
The phase transformation occurred under research low temperature etc. is also particularly significant.Data SNR and the unordered decrease of crystal substantially increase crystal parsing

In the insufficient situation of extraction raffinate nitrogen quantity, liquid nitrogen cannot be added in real time and guarantees to complete experiment.Therefore the application of liquid nitrogen cryogenics encounters pole
Big obstacle causes low temperature service efficiency generally lower.
Have in the Cryo Equipment of use at present, there are mainly two types of designs, and (1) one is liquid nitrogen containers and liquid nitrogen transfer line one
Bodyization design, this design good airproof performance, but detachability is poor, poor mobility, can not show liquid nitrogen surplus in liquid nitrogen container.
It is difficult to solve once entering steam ice blockage pipeline in liquid nitrogen container.(2) one is liquid nitrogen containers and liquid nitrogen transfer line to separate, and leads to
Clip is crossed to fix.This design detachability moves, and liquid nitrogen system and pipeline easy to clean have become mainstream in the ban
Liquid nitrogen system.However this cryogenic system is in actual use, due to adding liquid nitrogen every time, requires the lid liquid nitrogen container
Son opens removal, and the transfer tube for leading to single crystal diffractometer spray head is extracted, then liquid nitrogen is toppled over inward again or is injected with pipeline
Liquid nitrogen.Cryogenic system (1) leakproofness is poor, and liquid nitrogen lid is opened, and adds liquid nitrogen and is easy to make moisture in air coagulation band at liquid nitrogen mouth
Enter and form ice crystal in liquid nitrogen container, ice crystal, which is drawn into liquid nitrogen transfer line, is very easy to blocking pipeline；It (2) can not be in test process
In add liquid nitrogen in real time；It (3) can not real-time display liquid nitrogen surplus.So while low temperature liquid nitrogen test monocrystalline advantage is numerous, but
It is that the problem that pipeline blocking strips are come is numerous, causes cryogenic system to use simultaneously inconvenient.
