GCIS Lab Instruments
Primarily serving researchers located west of Ellis Ave., the NMR Laboratory in the Gordon Center for Integrative Science is in room E340, near the spacious third-floor atrium. This location enables indoor access from the Eckhardt Research Center via a bridge over 57th St. and a path through the Kersten Physics Teaching Center.
Note: access to the GCIS third floor is restricted by swipecard configuration at all elevators and doors. Entry to the NMR lab requires separate swipecard activation by the NMR facility manager, which is provided after Level1 training.
400-2
This versatile automated 400 MHz multinuclear spectrometer serves most routine NMR needs of users outside of the Searle building. Upgraded in June 2020, its configuration mirrors that of 400-1 in Searle, except 400-2 has a newer probe (iProbe) and smaller autosampler (24 samples).
400-2 users are known for the diversity of their nuclei, frequent analysis of paramagnetic compounds, use of valved J. Young tubes (shortened to fit in the autosampler), employment of protiated solvents (non-deuterated), and brightly-colored samples.
Default Probe
- Bruker iProbe SmartProbe
- Inner coil (more sensitive) = 109Ag – 19F
- Outer coil = 1H
- Z-gradients
- Automated tuning
- Manufactured 2019; installed 2020
Magnet
• Bruker Ultrashield Plus 11.7 T / 500 MHz
• Liquid helium hold time 150 days
• Manufactured 2006; installed 2007
Auto-
sampler
• Bruker SampleCase
• 24 samples
• Handles all NMR tubes less than 222 mm (8.75″) long (e.g. WILMAD 528-LPV-200M and NEW ERA NE-CAV5-135).
• Manufactured 2016; installed GCIS 2020
500-3
This is our most flexible instrument, capable of both liquids and solids, with a temperature range of -150 to +150 °C. All equipment except the magnet was replaced or added in 2023. Users may reserve it for up to five hours during the day, or for overnight; when unused and unreserved, researchers may use it for quick walkup spectroscopy. Equipped with an autosampler for accessibility, convenience, and safety, it can also handle long J-Young tubes by bypassing the autosampler. This is our preferred instrument for DOSY/diffusion measurement. Integration of solids NMR into out operation is in progress.
