Progress report on novel micro-GC chiral-MS
at Micro Nano Conference, University of Twente, NL, Nov 2022
At the international conference of the Netherlands Association of Micro Systems and Nanotechnology (MinacNed), which was held at the campus of the University of Twente, NL, on 1 and 2 November 2022, our public-private EFRO-consortium of MassSpecpecD BV, Qmicro by Sensirion, Radboud University, University of Twente and Saxion University of Applied Sciences presented a progress report on our novel prototype machine for direct MS analysis of the enantiomeric excess of mixtures of chiral molecules. The novel prototype apparatus combines micro-Gas Chromatography and direct chiral Mass Spectrometry using laser-based imaging of PhotoElectron Circular Dichroism (PECD).

Dr. Samir Sadek presented the latest results from our EFRO microGC-chiralMS prototype machine in a contributed poster, especially focusing on the high-level DSMC simulations and the microfabricated de Laval nozzle, fabricated by DRIE (Deep Reactive Ion Etching) technology at the Mesa+ Nanolab cleanroom at the University of Twente. The microfabricated de Laval nozzle is specially designed to couple the microGC output into the novel chiral Mass Spectrometer with extremely high density overlap between the supersonic gas jet and the focused high-repetition UV ultrafast laser radiation, see the poster of Samir at this link (Minac-poster-2022 pdf).
