Description

A kind of vacuum acid-dispelling device

Technical field

The utility model relates to analytical chemistry field, it is especially applied to a kind of pretreated vacuum of Elements and catches up with Sour device.

Background technique

In Elements, routinely to use with strong oxidizing property acid solution (including concentrated nitric acid, hydrofluoric acid, Hydrogen peroxide, potassium permanganate etc.) treatments of the sample is decomposed, so that the inorganic elements in sample is become ionic state and is dissolved in liquid.To sample After product digestion is decomposed, need to evaporate the acid solution of 80%-90%, with reach can the requirement tested of the above analysis instrument, acid solution is steamed It sends out and obtains the process of sample to be analysed and be referred to as to catch up with acid.

Vacuum acid-dispelling system is as the one kind for catching up with technic acid, and since it catches up with acid high-efficient, the acid gas being evaporated has net Change processing function, increasingly receives the approval of lab assistant.Vacuum acid-dispelling generally comprises heating component, acid gas confluence component, acid Gas collecting, purifying component and four part of vacuum pump component composition.After the completion of treatments of the sample decomposes, digest tube is placed in heating component In heated, acid solution due to heating become acid gas, by terminal vacuum pump generate negative pressure, so that acid gas is flowed through collection and purification group In part, thus by being fully cleaned up.
