Bruker EVOQ-TQ-DART with Elute UPLC (2026)

This brand new triple quadrupole mass spectrometer is currently on loan from Bruker Daltanics. The instrument is supporting our NIJ grant to both develop databases of replicate spectra of ESI-MS/MS and DART-MS/MS data and to develop the EASI algorithm towards the improved identification of seized drugs from their tandem mass spectra.

Bruker amaZon Ion Trap (~2012) Mass Spectrometer with DART, CTD, & ETD

This Bruker 3D ion trap is the work-horse for most of our CTD experiments. We duplicated the capability with our collaborators, Dr. Hélène Rogniaux and Dr. David Ropartz, at the BIBS MS platform INRAE in Nantes, France. This instrument is also compatible with UHPLC to accomplish UHPLC-CTD-MS of complex mixtures of oligosaccharides.

Thermo Scientific LTQ Orbitrap XL with HCD (new to us in 2025)

We purchased this used instrument in the summer of 2025. In addition to MS ⁿ capabilities with acquisition using the linear ion trap or the high-resolution Orbitrap, this instrument can also acquire HCD spectra using the Orbitrap.

Thermo Scientific Velos Pro (~2012) Linear Ion Trap Mass Spectrometer with ETD & CTD

Our linear ion trap is primarily used for MS ² and MS ⁿ fragmentation studies of novel psychoactive substances (NPSs). The instrument is also modified to enable Charge Transfer Dissociation (CTD) reactions.

Shimadzu Nexera X2 UHPLC with DAD UV-Vis detection (~2018)

Sometimes used to separate complex mixtures prior to MS/MS analysis on either of the mass spectrometers.
