Integration of High Performance Mass Spectrometry and Cryogenic Ion Spectroscopy: A Powerful Platform for Ultrasensitive Spectrochemical Analysis
Abstract
In this equipment proposal, we request $343K to enable the incorporation of commerciallyavailable high performance mass spectrometric methods into a next-generation experimentalplatform for cryogenic ion chemistry and spectroscopy. This is based on several uniqueproperties of the Thermo Orbitrap instrument (LTQ Orbitrap XL) that naturally interface to ourexisting, home-built cryogenic photofragmentation spectrometers based on time-of-flight massisolation and widely tunable pulsed laser excitation. The laser components and mass-selectiveinterface are already in place, and here we propose to adapt a commercial high resolution(refurbished) Thermo LTQ Orbitrap XL mass spectrometer ($208K) as part of the ion source,augmented by a custom cryogenic ion processing section based on commercial Thermocomponents and Janis cryo coolers ($135K) that will enable direct structural analysis of reactionintermediates characterized and manipulated using high performance mass spectrometrictechniques.
