Bruker AV-500
This spectrometer has a Hewlett-Packard Linux host workstation with 512 MB RAM and 40 GB disk space, HP laser printer, digital lock system, digital quadrature detection receiver system with oversampling, digital signal routing with full inverse detection capability, Z-axis field gradient module, and digital sample-temperature control unit with 0.1°C precision. Other specifications include a Magnex 500 MHz. actively-shielded standard-bore magnet with TMC vibration-damping legs, full pulse-shaping capability on both RF channels, and a 5mm 1H/BB VT probe with Z-gradient. This spectrometer was installed in late 2003.

Bruker Avance DRX-500
This spectrometer has a Silicon Graphics O2 host workstation with 128 MB RAM and 4 GB disk space, HP laser printer, digital lock system, digital quadrature detection receiver system with oversampling, digital signal routing with full inverse detection capability, Z-axis field gradient module, digital sample-temperature control unit with 0.1°C precision, and a refrigerated chilling unit for efficient sample-temperature control in the range 0-20°C. Other specifications include a Magnex 500 MHz. standard-bore magnet with TMC vibration-damping legs, three RF channels (one 1H-19F and two X), full pulse-shaping capability on all three RF channels, higher-power RF amplifiers for the X-channels, a 5mm 1H-19F/BB VT probe with Z-gradient and a 5mm 1H/13C/BB inverse-detection triple-resonance VT probe with Z-gradient. This spectrometer was installed in late 1998.

In June 2000 we had a "Level-1" solids upgrade installed on this spectrometer, which includes a higher-power 1H RF amplifier, a MAS control unit, and a 4mm CP-MAS probe. We gratefully acknowledge funding from the NSF CRIF program for this upgrade.

Bruker Avance DPX-400
This spectrometer has similar specifications to the 500 listed above. It has a Magnex 400 MHz. standard-bore magnet with TMC vibration-damping legs, two RF channels (one 1H-19F and one X) with no pulse-shaping, and a 5mm 1H/BB inverse-detection VT probe with Z-gradient. We also have a older 5mm C/H probe and a 10mm BB probe available for use on this system (thanks to Jim Beier of Bruker!). This spectrometer was installed in late 1998.

In January 2001 a new Bruker 5mm 1H-19F/BB Z-gradient probe was installed on this spectrometer. This will now become the standard probe for this spectrometer.

Both of these Bruker spectrometers share via NFS a 6GB disk that is physically located on our new SGI workstation located in the RRC-East lab. This new workstation is a Silicon Graphics O2 with an R5200 processor, 19" monitor, 128 MB RAM, 9 + 6 + 4 GB of disk space, and a 2 GB Jaz disk for archiving.

Bruker AM-400
Our Bruker AM-400 was installed in 1985 and has an Oxford standard-bore magnet. The system is equipped with an Aspect-3000 computer with an array processor, process controller, a 160 mB hard disk, and a BMT-100 tape backup unit. The Aspect-3000 is networked via a PC using the Open-Aspect Interface from M. R. Resources. The system has variable-temperature capability. The RF section consists of one broadband channel with ca. 250 watts pulse power for X-nuclei and 25 watts for 1H, and one 1H (decoupler) channel with ca. 40 watts CW power. The system has been modified to allow fixed attenuation of the transmitter output (for solids), and for O1 - O2 coherence (for TOCSY/ROESY). The standard probe for this spectrometer is now a Nalorac 5mm BB/1H-19F, which was installed in November 1996. Other probes available include Bruker 5mm 13C/1H, 5mm 1H-only and 10mm BB, and a Doty 5mm BB CP-MAS probe for solids.

Varian Mercury-Vx-300
Our Varian 300 system had a new Mercury-Vx BB console installed in late May of 2000. This console is a two-channel system with one 1H/19F channel with ca. 50 watts pulse power and one BB channel with ca. 125 watts. Currently the system uses a Nalorac 4-nucleus PLUS probe, which allows observation of 1H, 19F, 31P, and 13C nuclei without retuning the probe. The system has gradient shimming capability (using homospoil) but no VT equipment. We also have a 50-sample sample-changer setup interfaced with this spectrometer. The Varian system uses a Sun Ultra-5 workstation with 128 MB RAM and 20 GB disk, and is networked directly.

We gratefully acknowledge funding from the Dreyfus Foundation and the NSF CCLI A&I program, and UIC matching funds, for the purchase of this new console and the sample-changer.

Varian Gemini-2300
Our newly-acquired Varian Gemini-300 system is a two-channel system with one 1H/19F channel with ca. 50 watts pulse power and one BB channel with ca. 125 watts. Currently the system uses either a 5mm Varian 4-nucleus probe or a 5mm Varian dual broadband probe. The system has been upgraded to a Sun Ultra-10 workstation with 256 MB RAM and 20 GB disk, and is networked directly.

We gratefully acknowledge the generosity of Abbott Laboratories and Dr. Greg Mattingly for the donation of this spectrometer.
