Bruker ARX 500 MHz NMR

ARX500

The Bruker ARX-500 spectrometer was installed in 1993 and upgraded in 2001. This spectrometer is operated by a Silicon Graphics INDY R5000 workstation. It has two probes: a 5-mm broadband and a 5 mm inverse gradient broadband,  each of which is capable of variable temperature experiments (-150 to + 200 ºC for liquids). The Bruker ARX-500 spectrometer is a research-oriented instrument.  It is equipped with dual radiofrequency channels and used for molecules requiring better peak resolution, (complex) structure elucidation and variable temperature analyses on a wide range of organic, organometallic, inorganic, and biochemical systems, as well as natural products and host-guest systems. Experiments that are typically performed include 2D COSY, NOESY, ROESY, TOCSY, HSQC, HMQC, HMBC and selective excitation. Users can be trained to operate the ARX500 and must demonstrate proficiency if operating the instrument by users (Request for training).
