Nitrogen back-blowing simple device capable of promoting volatilization

The utility model relates to the technical field of biology, and discloses a simple nitrogen blowback device capable of promoting volatilization, which comprises a mass spectrum device, an SICRIT body is arranged on the side edge of the mass spectrum device, a suction head is arranged at the end part of the SICRIT body, a suction straight pipe is arranged at the bottom end of the suction head, a gas source box body is arranged on the side edge of the SICRIT body, and the gas source box body is arranged on the side edge of the gas source box body. A nitrogen generator is arranged in the gas source box body, a flow meter is arranged at the top of the nitrogen generator, and the nitrogen generator is communicated with the flow meter through a gas delivery pipe. Inert gas nitrogen is used for back flushing to promote volatilization of a sample, so that the sample is hardly interfered by other components; due to the application of the nozzle, the purchase cost is greatly reduced, the volatilization of volatile sub
