Development of Sheath-Flow Probe Electrospray Ionization Mass Spectrometry and Its Application to Real Time Pesticide Analysis
For
the real time and direct analysis of chemical constituents
from living beings and dry sample, sheath-flow probe electrospray
ionization mass spectrometry (SF-PESI-MS) has been newly developed.
The components from dry or semidry biological tissues can be extracted
using the solvent and picked up by the needle for electrospray. This
technique was applied to real-time pesticide analysis of living plants.
The results have been validated with that of a well-known system,
liquid extraction surface analysis mass spectrometry (LESA-MS). It
is demonstrated that SF-PESI-MS can produce reasonable ionization
efficiency, which is confirmed by LESA-MS
