In situ measurements of the dioxins (PXDD) are critical issue for environmental conservation. We have been developing an in situ measurement system using non-resonant multi-ionization processes of femto-second laser radiation.
The femto-second laser (800-nm wavelength, 150- fs pulse width, 10-Hz repetition
rate, and 1013-1015 W/cm2 laser intensity), ionization chamber, time-of -flight mass-spectrometer,
MCP ion detector and so on were used. Samples are injected into the chamber
with a pulse valve system. The samples are ionized by multi - ionization
process with high- intense femto-second laser pulses. The ionized samples
are accelerated by electrodes and detected by a micro channel plate giving
TOF data after passing through a flight tube.
