Description
Technical field
The utility model is related to hydrology-water quality sampling apparatus, particularly a kind of disposable automatic subpackaging sampling of hydrology-water quality
Bag, suitable for being used cooperatively with 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
It surveys.At present, after many monitoring stations have all selected the water-quality sampling point in arrangement field, specification to sample flow, water quality storage sample container
Selection is also particularly important.
Water quality storage sample container will select performance stabilization, 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, general glass leachable sodium, calcium, magnesium, silicon, boron etc. when storing water sample
Element when measuring these projects, should be avoided using glass container, to prevent new pollution；Container wall should not be absorbed or inhaled
