Description
Technical field
It is specifically a kind of sensitive containing volatile materials, oxygen the present invention relates to a kind of sampling container of water quality research
The separate assembling sampling bottle of property material water sample.
Background technology
Sampling bottle used in water quality research process is usually vial, and its shape is typically all narrow-mouthed bottle, i.e. bottle
Body portion is that particle size is cylindric, and bottleneck portion is that thin footpath is cylindric, and the transition portion between body and bottleneck is the ring in evagination
Arc surfaced.
Sampling bottle is generally that glass material is made, its weak point existed, and one is broken in carrying and transportation；
Two be the sample bottle for having contained water sample, after bottle sealing, is in micro- artesian condition in bottle, this allows for sample bottle and sample
Between product bottle or between sample bottle and other objects, slightly collide and just easily occur the damaged phenomenon of bottle.Moreover, transporting
Cheng Zhong, typically also packaging protecting is carried out in the outside for the sample bottle for containing water sample with flexible materials such as bubble cushions, and used
Flexible packages easily absorption or viscous glutinous pollutant, and bring into therewith in sample incubator, so as to pollute the storage of sample bottle
Dis environment, may produce indirect pollution to sample in bottle, add the probability of contaminated samples.
According to requirement of the collection containing volatile materials, the Sampling techniques specification of oxygen sensitivity material water sample, bottle is entered in water sample
When, water sample liquid level steadily rises in bottle planted agent, forbids the situation that water body acutely changes occur, that is, requires that the speed that liquid level rises should
Slowly change uniformly or smoothly, water injection rate can not be suddenly suddenly slow, suddenly big or suddenly small soon, so just can guarantee that water sample and wherein contents
The relative equilibrium of the molecular motion of matter, reduces disturbing phenomenon, it is to avoid because the volatile materials contained by water sample is escaped from water sample
Cause the problem of sample fidelity reduces with scattering and disappearing.
And when using the collection of existing sampling bottle containing volatile materials, the water sample of oxygen sensitivity material, inject and sample in water sample
The bottle section and the process of pass of bottle, the liquid level rate of climb are than more uniform, but when liquid level rises to bottle section and bottleneck
During changeover portion between section, due to the nonlinear change of volume, the speed for causing liquid level to rise is in non-linear increase, and
And, the acceleration that liquid level rises is nor a definite value, more up, and the acceleration of liquid level rising is bigger, the disturbance to water sample
Effect is stronger.Until intersection of the liquid level by changeover portion and pass, the acceleration that liquid level rises reaches maximum, water sample
Level of disruption also reach maximum, also, liquid level is after pass is risen into, and the acceleration that liquid level rises can be handed over from crossing
Maximum moment at remittance, involution was zero again, such acceleration change, reached maximum to the level of disruption of sample, and herein from
Bottleneck is close, adds the effusion of volatile materials and lost probability in water sample, reduces the fidelity of sample.
The closure that existing sampling bottle is used mainly has square thread lid（Similar mineral water bottle cap）With flat insert cover（Such as
Frosted mouthful glass stopper）Two major classes.The contact surface of both bottle caps and water in bottle sample is all planar structure.When water sample fills sampling bottle
Afterwards, due to water surface tension effect, the liquid level of bottle mouth position be slightly higher than bottleneck and in microprotrusion shape arcwall face.
During sampling bottle bottleneck being tamping with square thread bottle cap, the wink being in contact in the cambered surface water body of bottle mouth position with bottle cap inner plane
Between, the convex globoidal water body of bottle mouth position can be had by the extruding of bottle cap inner plane outside a small amount of liquid outflow sampling bottle, if firmly
Slightly larger or bottle cap the speed that screws is slightly fast, then while convex globoidal water body has part to be squeezed bottle outlet, the water sample in bottleneck
A small amount of or micro liquid may be carried under effect of inertia, thus a little sky can be reserved in the bottle mouth position of sampling bottle
Between, and filled by air, thus, in the sample bottle after bottle cap is fastened completely, the space filled by air will be produced, is made
Left air in sample bottle, so as to can not meet containing volatile materials, oxygen sensitivity material water sampling technical specification
It is required that, become waste sample.
In addition, in the actual mechanical process of sampling location, it is difficult to be disposed vertically sampling bottle.When water sample fills sampling bottle
Afterwards, when sampling bottle gradient is slightly larger, the liquid level water body of bottle mouth position convex globoidal will flow out bottleneck, make the sample after capping
Air has been left in bottle.And when sampling bottle gradient is less, each particle in surface of the liquid level water body of bottle mouth position convex globoidal
Component of the suffered gravity along cambered surface tangential direction is in the no more than surface tension of cambered surface water body, although can keep static flat
Weighing apparatus, but the center of gravity of the water body of convex globoidal can offset to the incline direction of sampling bottle, in the moment being in contact with bottle cap top surface, because by
Extrude and be easier to flow out outside bottle, make to leave air after capping in sample bottle, it is impossible to meet and contain volatile materials, oxygen sensitivity thing
The demand of technical standard of the water sampling of matter.
Although flat embedded sampling bottle cap disclosure satisfy that the associated specifications for filling up sample bottle, but be unfavorable for carrying and
Transport.Particularly glass bottle with frosted glass opening lid is not suitable for water containing volatile materials and oxygen-containing sensitive species of the collection in alkalescence
Sample.
By above-mentioned analysis, when sampling bottle is filling water sample and carries out bottle cap and tighten operation, careless slightly, Jiu Hui
Bubble is left in sample bottle, causes sampling to fail, bottle sampling must be only changed again, the sampling time is wasted, work effect is reduced
Rate.Moreover, pouring out the sampling bottle after water sample because leaving bubble, can't directly it reuse, it is necessary to take back laboratory through clear
Wash, dry, packing etc. after operation, could be continuing with the sampling process of next time.
According to the demand of technical standard containing volatile materials, oxygen sensitivity material water sampling, entered using existing sampling bottle
Row sampling, there is two kinds of operating methods.
The first operating method is that the effluent pipe mouth of sampler is stretched into sampling bottle, and effluent pipe mouth keeps one apart from bottom of bottle
Set a distance, during injection water sample, with the rising of liquid level in bottle, outlet pipe also together slow lifting.In the process, liquid level in bottle
It should keep constant with the distance between effluent pipe mouth, the outlet pipe in insertion bottle is answered vertical-lifting and must not shaken, to avoid water
The effusion of contained volatile materials and scattered and disappeared in sample.But in actual mechanical process, due to the water yield very little of sampler, fill
One bottle of water sample takes around the time of at least 5 minutes, and jitter phenomenon can all occur for the hand that operating personnel grip outlet pipe, and go out
The operation that above carries of water pipe also is difficult to accomplish to make the mouth of pipe keep constant state with rising the distance of liquid level, this allow for water sample by
There is the effusion of part and scattered and disappeared in the volatile materials contained in disturbance, sample, and declines the fidelity of gathered sample.And
And, during water sample injection sampling bottle, because the effluent pipe mouth of sampler is in the top of liquid level all the time, from mouth of pipe outflow
Tiny current be in contact all the time with air, it is this sampling environment under, the oxygen sensitive materials contained in water sample enter sample
Just oxidized during bottle, sample distortion situation naturally also can not just be avoided.
Second of operating method is that the effluent pipe mouth of sampler is extend into sampling bottle, and effluent pipe mouth is kept apart from bottom of bottle
A certain distance is constant, is slowly put down when water sample is injected into bottle, liquid level is continued rising up to close to bottle mouth position, then by effluent pipe mouth
Steady lifting, when effluent pipe mouth reaches bottle mouth position, water sample just fills sampling bottle.In this operating process, liquid level steadily rises,
Disturbance of the effluent pipe mouth to water sample is smaller, and contained volatile materials is difficult effusion in sample, the fidelity of the sample gathered compared with
It is high.
One common ground of both the above operating method is that all the effluent pipe mouth of sampler is extend into sampling bottle, and
Do not glue the situation of glutinous pollutant before sampling operation thoroughly if there is outlet pipe improper storage or cleaning, be easy for pollution
Thing is brought into sampling bottle, contaminated samples, causes sample distortion.In addition, for sampling operation personnel, only carrying out specially
After training on operation and long-term repetition training, be possible to grasp the committed step and the essential of exercise of sampling operation.But, by
In being all manual hand manipulation, therefore, the phenomenon for operating the interference of the human factor at scene to cause sampling to fail is still very general
All over and be difficult to avoid that.
