New PAN-CIGAR instrument:• Chemical Ionization Mass Spectrometer• Based on reaction of PA radicals with I-
• Fast (time resolution 0.25 – 2 seconds)• Sensitive (10-60 cts/pptv on background of
250 cts or less)• Very selective• Autonomous• Eight different PAN species measured during
ICARTT 2004• don’t miss the PAN-CIGAR Instrument talk:
