摘要： The instrument cold sprays a solution sample at a low temperature and desolvates the sample. Under this condition, a mass analysis is performed. The instrument comprises a needle pipe (8) through which the solution sample is passed, a sheath tube (24) formed coaxially with the needle pipe (8) and passing a temperature-controlled nebulizing gas therethrough, the above-described desolvation block (3), means for cooling the block (15), means for heating the block (4), and a temperature sensor (5) for detecting the temperature of the block (3). The block (3) has a passage for charged liquid droplets of the solution sample cold sprayed from the tip of the needle pipe (8), and acts to remove the solvent from the charged liquid droplets flowing through the passage. A coldspray mass spectrometer is offered which has a desolvation block whose temperature can be easily controlled. In the instrument, condensation of water and electrical leakage are prevented for a long time. The instrument can perform measurements stably and is easy to handle.

摘要： A time-of-flight mass spectrometer capable of cutting out a major portion of carrier gas-derived ions ahead of the ion reservoir. The ion source is of the electron impact type and has source magnets for deflecting some of the produced ions away from the center axis of the ion reservoir. Electrostatic lenses for promoting the deflection of the ions caused by the source magnets and a differentially pumped slit for cutting off the deflected ions are mounted downstream of the ion source.

摘要： There is disclosed an ion source for use in a mass spectrometer. The ion source has an ionization chamber, a pumping means for continuously pumping liquid sample, an inlet tube whose front end is located inside the ionization chamber to introduce the liquid sample delivered from the pumping means into the ionization chamber, a means for ionizing the sample introduced into the ionization chamber, and an exhaust pipe connected with the inlet tube. The ion source further includes a means for applying a pressure on the superfluous sample in the exhaust pipe by employing a gaseous material. Thus, the flow rate of the sample introduced into the ionization chamber through the inlet tube is stabilized.
