Abstract
A kind of novel nitrogen blows concentrating instrument, the utility model relates to solvent evaporation technique field, it comprises nitrogen gas generator, using nitrogen gas to seal off cavity, sample hose heating module, sample hose, special film system module, the top of nitrogen gas generator is provided with using nitrogen gas to seal off cavity, the top of using nitrogen gas to seal off cavity is provided with sample hose heating module, the inside of sample hose heating module is provided with several sample hose, and the bottom of sample hose is provided with special film system module.Utilize pressure differential as the power of nitrogen; membrane filtration system is as " automatic valve " between gas-liquid; because whole solvent evaporation process is all nitrogen or air; if when sample does not need nitrogen protection; initiatively form bubble and evaporate, sample splash phenomena can be avoided, and it being simple to have structure; arrange rationally, the advantages such as cost of manufacture is low.
Description
Technical field
The utility model relates to solvent evaporation technique field, is specifically related to a kind of novel nitrogen and blows concentrating instrument.
Background technology
Current nitrogen blows concentrating appts and is applied to laboratory widely as general experimental facilities, although once can out 10-30 sample, along with solvent volume reduces, when stream of nitrogen gas is not enough to blow to liquid level, also needs the height regulating draw point.Whole nitrogen is blown over journey air-flow and can not be controlled very well, and liquid solution is splashed, and causes sample concentration to lose, and easily causes the cross pollution of sample room.And owing to all needing to clean draw point at every turn, if do not washed clean clearly, very easily cause the cross pollution of sample room.
Utility model content
The purpose of this utility model is defect for prior art and deficiency; a kind of structure nitrogen simple, reasonable in design, easy to use is provided to blow concentrating instrument; utilize pressure differential as the power of nitrogen; membrane filtration system is as " automatic valve " between gas-liquid; because whole solvent evaporation process is all nitrogen or air; if when sample does not need nitrogen protection, initiatively form bubble and evaporate, sample splash phenomena can be avoided.
For achieving the above object, the technical solution adopted in the utility model is: it comprises nitrogen gas generator, using nitrogen gas to seal off cavity, sample hose heating module, sample hose, special film system module, the top of nitrogen gas generator is provided with using nitrogen gas to seal off cavity, the top of using nitrogen gas to seal off cavity is provided with sample hose heating module, the inside of sample hose heating module is provided with several sample hose, and the bottom of sample hose is provided with special film system module.
Pressure sensor device and pressure control device is provided with in described using nitrogen gas to seal off cavity.
Described sample hose heating module is provided with temperature control module.
The bottom of described sample hose is provided with gasket seal.
Principle of work of the present utility model: open nitrogen gas generator, makes to be full of nitrogen in using nitrogen gas to seal off cavity, and keeps certain pressure, can be realized by pressure sensor device and pressure control device; Open temperature control module, set temperature required, after balance, sample solution to be concentrated is added sample hose, nitrogen is set to required pressure, starts solvent evaporation and concentration; After having concentrated, take off sample hose, add required solvent and redissolve, use supporting piston rod, sample is pressed into sample analysis bottle.
After adopting said structure; the utility model beneficial effect is: a kind of novel nitrogen described in the utility model blows concentrating instrument; utilize pressure differential as the power of nitrogen; membrane filtration system is as " automatic valve " between gas-liquid; because whole solvent evaporation process is all nitrogen or air, if when sample does not need nitrogen protection, initiatively form bubble and evaporate; sample splash phenomena can be avoided, and have structure simple, arrange rationally, the advantage such as cost of manufacture is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Description of reference numerals:
1, nitrogen gas generator; 2, using nitrogen gas to seal off cavity; 3, sample hose heating module; 4, sample hose; 5, special film system module; 6, pressure sensor device; 7, pressure control device; 8, temperature control module; 9, gasket seal.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Referring to as shown in Figure 1, the technical scheme that this embodiment adopts is: it comprises nitrogen gas generator 1, using nitrogen gas to seal off cavity 2, sample hose heating module 3, sample hose 4, special film system module 5, the top of nitrogen gas generator 1 is provided with using nitrogen gas to seal off cavity 2, the top of using nitrogen gas to seal off cavity 2 is provided with sample hose heating module 3, the inside of sample hose heating module 3 is provided with several sample hose 4, and the bottom of sample hose 4 is provided with special film system module 5.
Pressure sensor device 6 and pressure control device 7 is provided with in described using nitrogen gas to seal off cavity 2.
Described sample hose heating module 3 is provided with temperature control module 8.
The bottom of described sample hose 4 is provided with gasket seal 9.
Described nitrogen gas generator 1 can replace with external Nitrogen source gases, such as nitrogen cylinder or external nitrogen gas generator.
The principle of work of this embodiment: open nitrogen gas generator 1, makes to be full of nitrogen in using nitrogen gas to seal off cavity 2, and keeps certain pressure, can be realized by pressure sensor device 6 and pressure control device 7; Open temperature control module 8, set temperature required, after balance, sample solution to be concentrated is added sample hose 4, nitrogen is set to required pressure, starts solvent evaporation and concentration; After having concentrated, take off sample hose 4, add required solvent and redissolve, use supporting piston rod, do not draw in figure and sample is pressed into sample analysis bottle.
After adopting said structure; this embodiment beneficial effect for: a kind of novel nitrogen described in this embodiment blows concentrating instrument; utilize pressure differential as the power of nitrogen; membrane filtration system as " automatic valve " between gas-liquid, because whole solvent evaporation process is all nitrogen, or air; if when sample does not need nitrogen protection; initiatively form bubble and evaporate, sample splash phenomena can be avoided, and have structure simple, arrange rationally, the advantage such as cost of manufacture is low.
