Description
Technical field
The utility model relates to a kind of auxiliary equipment of analysis Instrument equipment, refers in particular to a kind of water seal of atomic absorption spectrophotometer (AAS).
Background technology
Atomic absorption spectrophotometer (AAS) must have water seal arrangement when flame method is analyzed doing, and simple way is with discharge opeing hose disk coiled annular shape, and vertically fixing back is connected with the instrument leakage fluid dram, be full of water in the pipe after, promptly form water seal.The instrument that has then has supporting water seal arrangement, and the waste liquid that instrument is discharged is entered by the bottom inlet of device, and the top outlet by device flows out in the waste liquid bottle again, by forming water seal between device and the discharging tube.After finishing the analysis of organic solvent sample with atomic absorption spectrophotometer (AAS), the organic solvent of being discharged since proportion less than water, will swim in water in the water seal above, sewer pipe Long contact time organic solvent can make the pipe swelling, aging, leak.So the sewer pipe of instrument should adopt the pipe of organic solvent-resistant, and instrument standard configuration sewer pipe is not suitable for organic solution.Therefore after finishing the analysis of organic solvent, all the water in the water seal all must be discharged, organic solvent then can be discharged at every turn, prevents that to prevent the erosion of organic solvent to pipe, the more important thing is the instrument tempering from causing burning or blast.And when often discharging organic solvent, need dismantle dip pipe or emptied of water seal apparatus and the work of water filling is also cumbersome again when analyzing.
The utility model content
Technical matters of the present utility model provides a kind of water seal of atomic absorption spectrophotometer (AAS), this water seal both need not have been dismantled waste liquid in water seal and the emptying water seal after the analysis of at every turn finishing organic solvent, can easily all discharge the organic solvent in the water seal again, and also completely cut off organic solvent and constituted by pipeline and instrument and be communicated with, prevented tempering ignite organic solvent breaking out of fire and explosion accident.
Technical matters of the present utility model is solved by following scheme: a kind of water seal of atomic absorption spectrophotometer (AAS), comprise liquid storage bottle and fix and insert the dip pipe of its bottom with it, there is fixedly connected U trap to pass liquid storage bottle in the outside of liquid storage bottle, and fixedlys connected feeding dip pipe inside with dip pipe.On the U trap that the outside end of liquid storage bottle connects valve is housed.There is the fixing discharging tube that is communicated with the outside of liquid storage bottle, and valve is housed on the discharging tube.The U trap and the discharging tube of liquid storage bottle outside are interconnected.
When first the use, the leakage fluid dram of atomizer in the atomic absorption spectrophotometer (AAS) is linked to each other with flexible pipe with the inlet of dip pipe, the liquid outlet of water seal connects flexible pipe and is passed in the waste liquid bottle.Earlier with discharging tube valve and U trap valve closing, atomic absorption spectrophotometer (AAS) was sprayed with a certain amount of distilled water earlier before the beginning analytical work, make water enter into liquid storage bottle and form water seal with dip pipe by the dip pipe end opening, with the discharging tube valve open, can carry out the assay determination of sample then.
When analyzing aqueous sample, the waste liquid that enters into water seal directly is drained into waste liquid bottle by water seal discharging tube, liquid outlet.After the analysis of having carried out the organic solvent sample, because organic solvent proportion less than water, is difficult to discharge above the organic solvent in the dip pipe swims in.At this moment can earlier the combustion gas of atomic absorption spectrophotometer (AAS) be closed, continuation feeds combustion-supporting gas and sprays with distilled water; Then with water seal discharging tube valve closing, liquid level in water seal this moment rises gradually, after surpassing siphonal top, stop spraying, open the U trap valve, floating organic solvent and the part waste liquid of dip pipe internal upper part can enter U trap by water seal liquid outlet inflow waste liquid bottle under syphonic effect, drops to the disengaging siphon nozzle until liquid level; Close the U trap valve then, open the discharging tube valve, the state when water seal returns to sample analysis.
The utility model has the advantages that: the water seal of atomic absorption spectrophotometer (AAS), after having analyzed the sample of organic solvent, by closing the discharging tube valve, continuing to spray into distilled water makes the interior liquid level of dip pipe rise after exceeding U trap top, stop spraying, open operations such as U trap valve, floating organic solvent can be discharged under syphonic effect easily in the water seal, removed the trouble of waste liquid in the dismounting water seal emptying water seal from, effectively alleviated the erosion of organic solvent to pipeline, completely cut off being communicated with of organic solvent and instrument, stoped the generation of fire and blast.
