โœฆ Synopsis

The development ofan airborne instrument for the in-situ measurement of carbon monoxide is described. The technique is resonance-fluorescence of the (A~I7 ~ XI~) transition of CO in the VUV. The instrument achieves a detection limit of 1 ppb for an interaction time of 10 s from ground level up to an altitude of 34 km. Interferences from other stratospheric trace gases are negligible.

A method is proposed which enables simultaneous measurement of adsorption isotherms by means of nuclear magnetic resonance spectroscopy and the determination of NMR parameters. The method was checked for CO molecules sorbed in decationated Y-type zeolites.
