Abstract

PURPOSE: To obtain mass spector under optimal condition, by providing a switch interlocked with the supply of reaction gas for performing chemical ionization thereby switching the voltage supplied to each electrode of ion source to the optimal level for each measuring mode.
CONSTITUTION: It is comprised of reaction gas supplier 34, reaction gas switcher 48, and gas chromatograph. A voltage switcher comprising ripeller voltage exchanging switch 54 and ionization voltage exchanging switch 56 is located between the ion sources 30, 32, and each switch in said voltage exchanging device 52 are exchanged automatically in synchronization with the exchanging command for the reaction gas exchanging device 48.
