Other impurity are introduced, gained sample purity is high.
The device described in the utility model for removing residual acid solution, including for containing the sample containing residual acid solution
Quartz boat, in addition to tube furnace, quartz ampoule, inert gas generator and device for absorbing tail gas, the one of the quartz ampoule
The end at end or both ends is provided with the plugging device being detachably connected, and on described quartz ampoule there is one to enter stone for inert gas
The outlet outside entrance and a supplied gas and liquid discharge quartz ampoule in English pipe；Wherein,
Described quartz boat is placed in quartz ampoule, and quartz ampoule is placed in the furnace chamber of tube furnace, and described inert gas occurs
Device connects with the entrance pipe on quartz ampoule, and described device for absorbing tail gas connects with the export pipeline on quartz ampoule.
In said apparatus, described plugging device is preferably the quartz cover that bore is engaged with quartz ampoule external diameter.Work as plugging device
For quartz cover when, preferably will on quartz ampoule for inert gas enter quartz ampoule in entrance be opened on quartz cover.
In said apparatus, described device for absorbing tail gas can be specifically the container that can contain certain quantity of fluid, such as have
Body can be beaker, or cup with handles etc., preferably round-bottomed flask.What is contained in the device for absorbing tail gas is alkali
Liquid, the usually alkali lye such as sodium hydroxide solution or aqua calcis.
In said apparatus, described inert gas generator is that can provide inert gas (such as helium, neon, argon gas
Deng) device, be preferably argon tanks in the application.
Compared with prior art, apparatus structure described in the utility model is simple, and use is described in the utility model for utility model
Device and method can effectively remove the acid solution remained in sample, and without substantial amounts of dilution, it is short to remove the time of acid solution, and
Other impurity will not be introduced, gained sample purity is high.

Embodiment
The utility model is described in further detail with reference to specific embodiment, it is of the present utility model to more fully understand
Content, but the utility model is not limited to following examples.
Embodiment 1：Remove the device of residual acid solution
Fig. 1 is a kind of structural representation of embodiment of the device described in the utility model for removing and remaining acid solution.Such as
Shown in Fig. 1, the device described in the utility model for removing residual acid solution, including for containing the sample containing residual acid solution
Quartz boat 4, tube furnace 1, quartz ampoule 2, the argon tanks 3 and round-bottomed flask 6 that argon gas can be provided, contain in the round-bottomed flask 6
Equipped with a certain amount of alkali lye (can be specifically sodium hydroxide solution or aqua calcis etc.), the end at the both ends of quartz ampoule 2
Quartz cover 5 that is that bore is engaged with the external diameter of quartz ampoule 2 and being detachably connected is provided with head, in the stone close to argon tanks 3 one
An entrance entered for argon gas in quartz ampoule 2 is offered on English cover 5, a supplied gas and liquid are further opened with quartz ampoule 2
Outlet outside body discharge quartz ampoule 2；Described quartz boat 4 is placed in quartz ampoule 2, and quartz ampoule 2 is placed in the furnace chamber of tube furnace 1,
Connected between described argon tanks 3 and the entrance on quartz ampoule 2 by pipeline (can be specifically polyfluortetraethylene pipe etc.), it is described
Round-bottomed flask 6 and the outlet on quartz ampoule 2 between connected by pipeline (can be specifically polyfluortetraethylene pipe etc.).
Embodiment 2：The method that acid solution is remained in sample is removed using the described device of embodiment 1
Sample containing residual acid solution is placed in quartz boat 4, then quartz boat 4 is placed in quartz ampoule 2, afterwards will
