Abstract: Provided is a mass spectrometer including: an ion generation unit configured to provide an ion generation path; an ion selection unit configured to provide an ion selection path connected to the ion generation path; a reaction unit configured to provide a reaction path connected to the ion selection path; a second ion selection unit configured to provide a second ion selection path connected to the reaction path; and an ion detection unit coupled to the second ion selection unit. The ion selection path and the reaction path extend in a first direction, and the reaction unit includes: a reaction pipe extending in the first direction to define the reaction path; and a sample inflow pipe coupled to the reaction pipe. The sample inflow pipe provides a sample inflow path connected to the reaction path, and the sample inflow path includes an inclined path. The inclined path extends to form an acute angle (?) with respect to the first direction.
