The
Kenttämaa
group uses nine different mass spectrometers to conduct various types of analytical and physical organic mass spectrometry research. Most of the instruments have been optimized for use in a specific area of our research. Each instrument also has a graduate student supervisor who is responsible for its maintenance and upkeep. |
NEL
NEL is a 3-Tesla Finnigan FTMS 2001 dual-cell FT-ICR mass spectrometer that uses EI/CI for ion generation. This instrument is equipped with two thermal solids probes and multiple leak valve inlets. It is primarily used to study the kinetics of the reactions of gas-phase bi- and polyradicals.
|
TIC
TIC is a 3-Tesla Nicolet FTMS 2000 dual-cell FT-ICR mass spectrometer that uses EI/CI for ion generation. This instrument is equipped with a high-power, “fiberless” LIAD setup. It is primarily used for petroleum analysis via chemical ionization and for the study of radical-induced degradation of biomolecules.
|
LIL
LIL is a 7-Tesla Finnigan TQ-80 dual-cell FT-ICR mass spectrometer that uses EI/CI for ion generation. This instrument is equipped with an automated, “fiberless” LIAD probe.It is primarily used for studying complex petroleum fractions.
|
HAL
HAL is a 3-Tesla Extrel FTMS 2001 dual-cell FT-ICR mass spectrometer that uses EI/CI for ion generation. This instrument is primarily used to develop novel ion-molecule reactions for the identification of various functional groups.
|
STE
STE is a Finnigan LTQ linear quadrupole ion trap mass spectrometer that uses ESI/APCI for ion generation. This instrument has a home-built reagent mixing manifold for studying ion-molecule reactions.It is coupled with a Finnigan Surveyor HPLC system, which allows LC/MSn experiments.
|
EVE
EVE is a Finnigan LTQ linear quadrupole ion trap mass spectrometer that uses ESI/APCI for ion generation.This instrument has been modified to accept the LIAD probe.
|
GIB
GIB is a home-built flowing-afterglow guided ion beam triple quadrupole mass spectrometer that uses EI/CI for ion generation.It is used to determine various thermochemical values, such as bond dissociation energies.
|
ZOE
ZOE is a Finnigan TSQ 7000 triple quadrupole mass spectrometer that uses ESI/APCI for ion generation.It has been modified to allow the introduction of neutral molecules into q2 for ion-molecule reactions.It is coupled with a TSP HPLC system, which allows LC/MS and LC/MS/MS experiments.
|
ZED
ZED is a Finnigan TSQ 7000 triple quadrupole mass spectrometer that uses ESI/APCI for ion generation.This instrument is currently being modified to accept the LIAD probe.
