Problems solved by technology

Wet digestion often requires the use of strong acids and corrosive liquids such as sulfuric acid, nitric acid, perchloric acid, hydrogen peroxide, and hydrochloric acid. After digestion, it is often necessary to transfer the digestion solution to a volumetric flask for constant volume. It takes a lot of time and the transfer process involves strong acids or strong corrosive liquids, which may even damage the health of operators if they are careless

Abstract

The invention provides a batch transfer constant volume device of a wet digestion type digestion solution. The batch transfer constant volume device is characterized in that a water storage bucket is connected with a water separator through a silica gel tube, and a vacuum pump is arranged on the silica gel tube; the water separator is connected with two or more than second silica gel tubes, a spray cleaning head is arranged at the tube head of each second silica gel tube, the spray cleaning heads extend to boiling tubes, and two or more boiling tubes are arranged; each spray cleaning head corresponds to one digestion solution suction tube, the digestion solution suction tubes extend to the boiling tubes, and two or more digestion solution suction tubes are arranged; and the digestion solution suction tubes are connected with constant volume tubes by polytetrafluoroethylene tubes, and two or more polytetrafluoroethylene tubes are arranged. By adoption of the batch transfer constant volume device of wet digestion type digestion solution and the control module thereof, provided by the invention, batch constant volume transfer of the wet digestion type digestion solution can be realized.

Description

Technical field [0001] The invention relates to the field of experimental equipment, in particular to a wet digestion digestion solution batch transfer constant volume device and a control module thereof. Background technique [0002] Wet digestion is one of the important pre-treatment methods for animal, plant, soil and other samples for chemical component analysis and sample processing. Wet digestion often requires the use of strong acid and corrosive liquids such as sulfuric acid, nitric acid, perchloric acid, hydrogen peroxide, and hydrochloric acid. After the digestion is completed, it is often necessary to transfer the digestion solution to a volumetric flask for constant volume. It takes a lot of time and the transfer process involves strong acids or strong corrosive liquids, which may even harm the health of the operators. Summary of the invention [0003] The purpose of the present invention is to provide a device for batch transfer and constant volume of digestion liqui...
