PROBLEM TO BE SOLVED: To provide a reservoir for a mass analyzer capable of analyzing a high boiling point component in crude oil at about 400°C. SOLUTION: The reservoir 3 made of glass is miniaturized and a stirring mechanism is provided in the reservoir. The reservoir is made of glass and the stirring mechanism is a rotor 7 remotely rotated by magnetic force from the outside of the reservoir. Further, the reservoir has a volume which is 1/n a standard volume (1-2 l) and the conductance between the reservoir and an ion source has a value which is 1/n a standard value (1×10<SP>-3</SP>l/sec). Furthermore, the internal pressure of the reservoir has a value which is n-times a standard value (10-100 Pa). Herein, the value of n is 2≤n≤100, most preferably n≈10. COPYRIGHT: (C)2007,JPO&INPIT
