Title

Experimental Design of a Rotor Induce Collision Cell (RICC) to study Racemization of Amino Acids at Hypervelocity Impacts Prior to Mass Analysis in Space.

Abstract

Ion Neutral Mass Spectrometer (INMS) was the instrument used to sample gas molecules during the CASSINI mission. However, due to the kinetic energy of impact caused by hypervelocity collisions energy between sampled neutral molecules and the walls of the instrument’s antechamber, significant chemical changes occurred to the native species prior to ionization and mass analysis. Despite the efforts made to understand the effects of hypervelocity collisions that occur prior to mass analysis in space, not much has been done to study hypervelocity collisions of products experimentally. A Rotor Induced Collision Cell (RICC) is being developed to study the hypervelocity collisions products of neutrals, understanding of which may be a step up to facilitate the identification of native sampled species via mass spectrometry in space.
