Description
Technical field
The present invention relates to the digestion procedure in the pre-treatment field, especially sample of metallic element analysis.
Background technology
In the sample, metallic element is often combined or inorganic with other with the organic matter such as protein, carbohydrate, lipid
Composition is mixed, it is necessary to be converted into the ion existed in solution by pre-treatment and analyzed.
Conventional pretreatment technology mainly has dry ashing, micro-wave digestion, Wet etc. at present.Dry ashing is because portion
Point Low-Temperature Element rate of recovery is low, background values is high and is eliminated in trace, ultra trace analysis field face.Micro-wave digestion be by sample with
Excess acid mixing is placed in closed container is cleared up with microwave heating；Conventional wet, which is cleared up, usually mixes sample with excess acid
Together in being cleared up in open-top receptacle in electrically heated mode.Both approaches are required to add excessive acid, are clearing up completion
Excessive acid is rushed again afterwards, reagent blank is not only increased, also serious waste reagent and time.To avoid reaction excessively acute
It is strong, also usually need the pre- of long period to clear up, also need to remove and add digestion solution often in digestion process, efficiency is very low；
It is discharged into air in nitrogen oxides, the acid gas cleared up, catch up with sour process to produce and will also result in environmental pollution.
In view of the defect that prior art is present, the present invention provides one kind and clears up instrument, by changing the feed postition of acid, realize
The automatic on-line of digestion solution is added in right amount, thus save it is pre- clear up, catch up with sour process, solve to clear up inefficiency, pollution environment
Problem.
The content of the invention
The present invention provides one kind and clears up instrument, including digestion tube, constant pressure funnel, adapter, appendix I, condensation buffering
Bottle, appendix II, vent gas treatment bottle, appendix III, vavuum pump, heater.It is digestion tube, constant pressure funnel, adapter, defeated
Tracheae I, condensation surge flask, appendix II, vent gas treatment bottle, appendix III, vavuum pump are sequentially connected, and constitute closed system.Plus
Hot charging is equipped with the hole for placing digestion tube, and digestion tube is respectively placed in hole.Constant pressure funnel has the cock of controllable flow velocity, is disappearing
What can be stablized in solution preocess digestion solution is added dropwise in digestion tube with friction speed.
Further, the digestion tube, constant pressure funnel, cock are glass or fluoroplastics material.
Further, the digestion tube and constant pressure funnel lower contact surface and constant pressure funnel top and adapter
Contact surface be frosting or shiny surface, it is closely sealed functional.
Further, the appendix I, appendix II, appendix III are thermal resistance and acid-alkali resistance material, the condensation surge flask
For heat-resisting acidproof material, the vent gas treatment bottle is alkali-resistant material.
Further, the condensation surge flask has lid with vent gas treatment bottle, has covered an appropriate number of hole defeated to insert
Tracheae, it is salable after covering.
Further, the condensation surge flask, which had on even open to atmosphere communicating pipe, communicating pipe, cock；Communicating pipe, lower end was high
In the acid solution liquid level of condensation.
Further, the alkali lye for absorbing NOx is filled in the vent gas treatment bottle.
Further, the front end connecting adapter of appendix I, the end of appendix I is inserted with the front end of appendix II and condensed
Below surge flask, the end of appendix II insertion vent gas treatment bottle alkali lye liquid level, the front end of appendix III insertion vent gas treatment bottle alkali lye
It is more than liquid level.The end of appendix III connects vavuum pump.The acid vapor produced in digestion process is condensed into acid in condensation surge flask
Liquid, oxides of nitrogen gas is fully absorbed in vent gas treatment bottle by alkali lye.
Further, the heater is graphite heating device, and heating-up temperature is stably and controllable, control range be room temperature extremely
400℃。
Compared with prior art, the invention has the advantages that：Digestion solution is added dropwise in sample in digestion process
Cleared up, stop addition after clearing up completely, be prevented effectively from and clear up the violent reaction of incipient stage and the excess of digestion solution adds
Enter, thus save it is pre- clear up and catch up with sour process, greatly reduce the pre-treatment time；It is closed to clear up environment and vent gas treatment environment is true
Protect pernicious gas to be fully processed, it is to avoid pollution to environment.
