Chiral Discrimination in the Gas Phase Using Different Transducers: Thickness Shear Mode Resonators and Reflectometric Interference Spectroscopy

摘要

The discrimination of optical isomers (enantiomers) in the gas phase has been performed using two different analyti- cal tools: thickness shear mode resonators(TSMRs) and reflectometric interference spectroscopy(RIFS). The selective coatings included both enantiomers ((S)-and （R）-receptor) of a Chirasil-Val derivative(stationary phase material in GC) with octyl side chains. Successful dis- crimination of the enantiomers of different types of ana- lytes(amino acids and lactates) was achieved.
