Zusammenfassung:The invention discloses a device for quantitatively adding carrier gas and an application method thereof.A pressure control module is used for controlling the gas outlet pressure of a carrier gas steel cylinder, a time relay is used for controlling the carrier gas circulation time, and within countdown of the carrier gas circulation time, the time relay is switched on, a normally-closed electromagnetic valve is powered on, and the normally-closed electromagnetic valve is in an open state; and after the countdown of the circulation time of the carrier gas is finished, the time relay is switched off, the normally-closed electromagnetic valve is switched off, the normally-closed electromagnetic valve is in a closed state, and the gas cannot pass through, so that the quantitative loading of the carrier gas is realized without depending on a glass needle cylinder to quantify the carrier gas. The technical problems that in an existing quantitative carrier gas adding mode, the volume of carrier gas needs to be quant
