En la ionización química los átomos gaseosos de la muestra (tanto de un sistema de entrada indirecto como de una sonda caliente) se ionizan al colisionar con los iones producidos al bombardear con electrones un exceso de gas reactivo (normalmente metano). Normalmente se utilizan iones negativos [...] 2, record 1, Spanish, - ionizaci%C3%B3n%20qu%C3%ADmica
