MICROSPRAY COLUMN, MASS SPECTROMETER, AND MASS SPECTROMETRY |
摘要 |
A problem is to provide a microspray column capable of increasing the ionization efficiency, and a high sensitive mass spectrometer and a mass spectrometric method using such a microspray column. For solving this problem, we provide a column for introducing a sample in an ionization source of a mass spectrometer (ESI/MS) being designed to ionize a sample molecule with electrospray and introduce it into an analyzer, has structural features of: (1) 0.5 mu m or less in an inner diameter of a tip opening of the column; (2) 0.5 mu m or more and 5 mu m or less in a particle size of a column filler; and (3) fritless, a microspray column having the above (1) to (3), a mass spectrometer having such a microspray column in an ionization source, and a mass spectrometric method capable of performing a nonoflow electrospray with the microspray column. <IMAGE>
