SAMPLE PREPARATOR FOR MASS SPECTROMETRY

Title:

SAMPLE PREPARATOR FOR MASS SPECTROMETRY

Document Type and Number:

Japanese Patent JP2003098154

Kind Code:

A

Abstract:

To easily specify a location of laser irradiation for ionization.

Air is supplied by bringing a micro nozzle 12 for supplying air closely to one end of sample solution 8. In a dispensation spot 6, evaporation from the surface of the sample solution 8 is activated at a part supplied with air and crystallization progresses abruptly as compared with other parts. Subsequently, a gradient of concentration is generated in the sample solution due to local crystallization thereof and noncrystallized solute flows to the vicinity of a crystal and crystallizes. As a result, a crystal grows around the part supplied with air. Optimal location of laser irradiation can be facilitated for such a crystal and high speed automatic processing can be realized by delivering the positional information of the micro nozzle for air supply to a TOFMS and determining the laser irradiation position based on that positional information.
