Description
Technical field
The invention provides a kind of device that can be used for the smoked sample of acid, belong to equipment of chemical industry technical field, specifically
It is related to the smoked device of multilamellar acid that a kind of closed can control release acid vapor.It provides a kind of acid convenient to operation and smokes dress
Put, hold and can disposably be placed and taken out during sample, improve work efficiency and reduce the acid vapour leakage aerial time cruelly, reduce
The infringement to health for the acid, can be saved to sour use using a switching device simultaneously.
Background technology
Country is greatly developing the blue economy in ocean at present, and the emerging field such as carbon remittance fishery progressively rises, country
Ocean research is increasingly paid attention to, how deeper into research ocean be just particularly important, the particulate organic carbon in water body
(POC), to reaction sea area water environment index, the food source of aquaculture organism is all important parameter to the organic carbon in deposit.As
What accurately analyzes the important prerequisite that sample data is really reaction sea area index, either particulate organic carbon is divided at present
Analysis, or pretreatment process is required for organic carbon content, isotopic analysis in deposit, smoked by pickling or acid
Method is by inorganic carbon removal.Particulate organic carbon can only be smoked to remove DIC by acid, and deposit is different according to different samples
Instrument requirements and experiment condition can be carried out by sour smoked or pickling two ways, so the smoked process of acid is for pretreatment
Experiment is a very important step.In current experiment condition, device is smoked in the special acid of neither one, and major part is to utilize other
Various glass containers manufacture an airtight environment, concentrated hydrochloric acid and sample are concurrently placed in airtight glass container, using dense
The volatility of hydrochloric acid smokes the effect of sample to reach acid.In order that the smoked effect of acid is more preferably, it is necessary for putting concentrated hydrochloric acid solution
In the bottommost of hermetic container, so just can make acid vapor that the acidizing effect of sample is reached most preferably, then result in sour smoked
During sample, hydrochloric acid easily wastes first, is open state and places and have to before sample first to due to placing acid smoked container during sample
Concentrated hydrochloric acid is inserted in hermetic container, so concentrated hydrochloric acid will certainly evaporate in the air, causes the loss of concentrated hydrochloric acid, secondly experiment people
Member can touch the acid vapor evaporateing in the air in operation, and the health of human body is caused necessarily to endanger.Finally, work as sample
When product amount is big, when sample being placed and taken out one by one is made the volatilization also increasing concentrated hydrochloric acid while acid smoked complex operation
Between and experimenter cruelly leak the time in acid vapor.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of multilamellar acid smoked device, and the smoked sample of the convenient acid of described device takes
The volatilization of concentrated hydrochloric acid while putting, can be controlled to a certain extent, can also save while protection health and sour is disappeared
Consumption.
The present invention employs the following technical solutions and is achieved：
Device is smoked in a kind of multilamellar acid, and it includes container body, container cover, reagent switching device, principal post and specimen holder；
It is provided with reagent dividing plate at the 20cm of container body bottom, reagent dividing plate is fixed in container, described reagent dividing plate band
