Abstract

The invention discloses a full-automatic inorganic sample pretreatment acid-removing constant volume reaching instrument which comprises an interface module used in combination with a single-mode microwave digestion instrument; a heating module used for heating according to set temperature after cleaning is completed; a cleaning module for cleaning a digestion tank placed in a cleaning position for three times; a nine-way valve module for directly adding an acid for digestion and reaching a constant volume; a three-axis module used to suck, from a sample sending position, a solution in the digestion tank to put into a sample bottle placed in the heating module and move the digestion tank to the cleaning position; a constant volume reaching module for precise positioning of liquid surface and full transferring of the solution to a target position; and a control module. Wet digestion and microwave digestion are combined in one, the full-automatic inorganic sample pretreatment acid-removing volume metering instrument can independently process a wet digestion sample, by combination of the two methods, most of inorganic analytical samples can be processed, after digestion of the sample,the acid is removed, and the solution is diluted to a desired volume, and the full-automatic inorganic sample pretreatment acid-removing volume metering instrument can realize the full-automatic sample pretreatment.

Description

technical field [0001] The invention relates to an inorganic sample pretreatment technology, in particular to a full-automatic inorganic sample pretreatment acid-discharging instrument. Background technique [0002] At present, with the development of society and the improvement of requirements for industrial production and environment, the production of high-quality products and the maintenance of ecological environment are one of the important strategic goals of my country's sustainable development. The quality control of samples in geology, metallurgy, food, petrochemical, biopharmaceutical and other fields involves sample pretreatment and component analysis. However, there are many types of samples, involving organic matter, metal organic matter and inorganic matter, and the sample state involves solid, liquid and gaseous states, including Dust, colloidal suspended solids, aerosols, the properties of samples are flammable and explosive, toxic and harmful, stable and unst...
