Description
Technical field
The present invention relates to hydrology-water quality sampling apparatus, particularly a kind of disposable automatic subpackaging sampler bag of hydrology-water quality, fit
It is used cooperatively in hydrology-water quality automatic subpackaging sampler.
Background technology
In recent years, process of industrialization promotes rapidly.In face of new situations, urban water-body also becomes by contaminated present situation
It is more serious.In the state of at present, many regional waters are all being polluted, and this present situation is also objectively demonstrating water
Matter samples and the significance of Water-quality control.From the point of view of the overall process of water quality monitoring, spot sampling should belong to key therein
Link, meanwhile, also constitute first step.After spot sampling, if accurate, comprehensive water quality sample can be obtained,
Contribute to the smooth expansion of water quality monitoring；, whereas if spot sampling has larger error, then it is likely to influence the prison in later stage
Survey.At present, many monitoring stations all have selected the water-quality sampling point in arrangement field, after specification samples flow, water quality storage sample container
Selection is also particularly important.
Water quality storage sample container will select stable performance, should not adsorb and hold made of the low material of prediction component, impurity content
Device, as the container of polyethylene and Pyrex material be in routine monitoring it is widely used, it is also possible to quartz or polytetrafluoroethylene (PTFE)
Manufactured container.Container should not cause new contamination, in general glass leachable sodium, calcium, magnesium, silicon, boron etc. when storing water sample
Element, when determining these projects, it should avoid using glass container, to prevent new pollution；Container wall should not absorb or inhale
Attached some components to be measured, in general glass container absorption trace metal, polyethylene etc. plastic containers absorption organic substance, phosphate
And oils；Container should not directly chemically react with water sample, can be reacted between the fluoride and glass container in water sample,
These influences of reflection for water quality sampling are all destructive, have impact on water sample for the representative and complete of the ground water source
Property.According to the different storage sample container of the different choice of various regions water quality monitoring project, more common is polythene material or glass material
The sampling bottle of different volumes made of material, it is more convenient suitable for water sample storage, but often there is also problems with：
1st, sampling bottle is often reused, it is necessary to which laboratory personnel is more to sampling bottle progress after once storage sample task is completed
Secondary cleaning, sample collector is also required to before spot sampling sampling bottle is carried out repeatedly to swing with the water of sampling position wash, avoid residual in bottle
The water stayed pollutes to this water sample gathered, influences monitoring result.
2nd, the sampling bottle of many different volumes is required for due to sampling every time, the space shared by bottle is bigger, and takes
Band is more inconvenient, certain trouble to sampling work band.
3rd, sampling location is washed needs and taken a substantial amount of time to swinging for sampling bottle, and the collection to sewage needs also exist for adopting
Sample personnel carry out repeatedly swinging to sampling bottle and washed with the water of sampling position, and this just brings certain prestige to the health of sample collector
The side of body.
To sum up, current water sample storage container is not only inconvenient to carry, and is also wasted time and energy during use, causes
Operating efficiency is relatively low, job security is poor, sample collector's labor intensity is big, swung before use wash it is insufficient can also be to monitoring accuracy
Bring certain influence.
