摘要: Abstract : Atmospheric free radicals play an important role in early all atmospheric cycles. The focus of this research was to continue characterizing the PEroxy Radical measurement by Chemical Amplification (PERCA) method first investigated Cantrell (1983, 1984), then Buhr (1986). Experiments proved original model PERCA developed too simple. New instrument modifications have insured optimum performance for peroxy radical clean, dry environments. is currently calibrated under laboratory conditions observing decay HO2 a formaldehyde photolysis system. reported chain lengths 600 are reasonable agreement with previously methods. Theses.
