NMR Spectrometer: 500-MHz WB Bruker (Imaging) - (Bastiat)
Quick Specs
- Wide-bore (WB) magnet with 500 MHz 1H frequency
- Microscopic imaging (μ-MRI or micro-magnetic resonance imaging)
- Spatially localized and time-resolved spectroscopy, e.g., magnetic resonance spectroscopy (MRS)
- Mass transport (flow and diffusion) measurements
- Unique in vivo accessories:
- Microscopy flow cells for tissues and biofilms
- Metabolomics (chemostat) bioreactor
Highlighted Research Applications
EMSL's Bruker 500-MHz WB spectrometer is uniquely tailored for in vivo studies:
- Microbial biofilms relevant to human health and environmental processes
- Animal and plant tissue samples
- Microbial suspensions relevant to biofuels and other bioproducts
- Small animals via non-invasive μ-MRI and MRS.
Researchers may operate the system independently and can be trained to manage fully self-directed operations. Collaborative work with staff scientists is encouraged.
