Embodiment Construction
[0021] The present application provides a device for preventing corrosion of a digestion instrument, by placing the graphite digestion instrument in the operating room, and setting a ventilation window in the operating room, and connecting the first air pump with the cavity of the graphite digestion instrument , so that positive pressure air is delivered to the cavity of the graphite digestion instrument through the first air pump. In this way, each gap in the cavity of the graphite digestion instrument will overflow the positive pressure air, and then the acid mist in the cavity of the graphite digestion instrument will be driven out through the positive pressure air, so that the acid mist cannot enter the cavity of the graphite digestion instrument In the various mechanical and electronic devices inside the body, the positive pressure air is connected to the acid mist through the exhaust window, which effectively solves the problem of corrosion of the graphite digestion instr...

The invention discloses equipment for preventing a digestion instrument from being corroded. The equipment comprises an operation room which is provided with an air draft window; the graphite digestion instrument is arranged in the operation chamber; and the first air pump is connected with the cavity of the graphite digestion instrument. The first air pump is connected with the cavity of the graphite digester, so that positive pressure air is conveyed into the cavity of the graphite digester through the first air pump. In this way, the acid mist in the cavity of the graphite digestion instrument is expelled outwards through the positive pressure air. Therefore, the acid mist cannot enter each mechanical and electronic device in the cavity of the graphite digestion instrument; finally, thepositive pressure air is communicated with the acid mist through the air draft window to be pumped out, the technical problem that in the prior art, due to the fact that the concentration of the acidmist in the graphite digestion instrument is too high, machines and electronic devices of the graphite digestion instrument are corroded is effectively solved, and the graphite digestion instrument has the advantages of being simple in structure and wide in applicability.
Description
technical field [0001] The invention relates to the technical field of experimental instruments, in particular to a device for preventing corrosion of a digestion instrument. Background technique [0002] Digestion, also known as wet digestion, is a method of destroying organic or reducing substances in a sample by using acid or lye and heating. There are generally three existing digestion methods: electric heating plate digestion, microwave digestion and graphite digestion; among them, electric heating plate digestion is a fully manual digestion method; microwave digestion needs to put a certain amount of solvent and samples into a closed digestion tank at the same time in advance, and then Put it into a microwave digestion instrument for digestion; graphite digestion is divided into manual and automatic. The principle of manual graphite digestion is the same as that of electric heating plate digestion. Fully automatic graphite digestion can control the heating temperature,...
