Problems solved by technology

[0002] Mass spectrometry is a detection technology with very high accuracy and reliability. Mass spectrometry needs to test the time of flight of ions in a vacuum environment. The current solution is generally to send the sample into the vacuum chamber, which cannot continuously inject samples. When replacing the sample When the vacuum in the vacuum chamber is leaked, it needs to be re-evacuated. After the sample is injected, it needs to wait for the vacuum to be re-established. It takes tens of minutes or several hours. short

Abstract

The invention discloses a continuous injection vacuum chamber. The continuous injection vacuum chamber includes a vacuum chamber provided with an ion exciter and an ion detector, a vacuum gauge communicated with the vacuum chamber, and a vacuum pump. The continuous injection vacuum chamber is advantaged in that continuous injection can be achieved, work efficiency is improved, and service life isimproved.

Description

Technical field: [0001] The invention relates to a vacuum chamber in the field of biological mass spectrometry detection, in particular to a vacuum chamber with good sealing performance, fast vacuum establishment and maintenance speed, continuous sampling and continuous detection. Background technique: [0002] Mass spectrometry is a detection technology with very high accuracy and reliability. Mass spectrometry needs to test the time of flight of ions in a vacuum environment. The current solution is generally to send the sample into the vacuum chamber, which cannot continuously inject samples. When replacing the sample When the vacuum in the vacuum chamber is leaked, it needs to be re-evacuated. After the sample is injected, it needs to wait for the vacuum to be re-established. It takes tens of minutes or several hours. short. Invention content: [0003] The technical problem to be solved by the present invention is to provide a continuous sampling vacuum chamber capable...
