LASER DESORPTION - ELECTROSPRAY ION (ESI) SOURCE FOR MASS SPECTROMETERS |
摘要 |
An ion source is disclosed for forming multiply-charged analyte ions from a solid sample. A beam of pulsed radiation is directed onto a portion of the sample to desorb analyte molecules. A retaining structure holding a solvent volume is positioned proximate the sample. Desorbed analyte molecules contact a free surface of the solvent and pass into solution. The solution is then conveyed through an outlet passageway to an electrospray apparatus, which introduces a spray of charged solvent droplets into an ionization chamber. |
