In Observance of U.S. Holiday, Martin Luther King Jr. Day, Agilent Cross Lab/ iLab Operations Software will be closed during U.S. hours on Monday January 21st, 2019. We will resume regular U.S. support hours on Tuesday January 22nd, 2018. EU and APAC Support will remain open during this time. For urgent matters, please add "Urgent" to the ticket/ email subject or press "1", when prompted, to escalate a call on the iLab Support phone and we will prioritize those requests first.

Core - NMR

Overview of Services

The DFCI NMR core offers walk-up NMR spectroscopy capabilities for samples of moderate concentration and complexity. This is a user-based NMR facility; users generally run their own experiments on the NMR spectrometer, with staff available to offer instruction and guidance on the best experiments for any particular job.


Nuclear magnetic resonance spectroscopy is a powerful tool for studying structural and conformational parameters of molecules, and is a flexible technique for measuring binding of ligands to cognate macromolecules. This tool is vital for the chemical analysis of organic compounds, compounds discovered in small-molecule screens, and large molecules, such as carbohydrates and proteins found to have potential biologic importance.


500 MHz Bruker Avance III two-channel console, equipped with a temperature controlled SampleJet automation system. Acquisition capabilities include walk-up proton, fluorine, and carbon NMR, routine 1D and 2D experiments, variable temperature. The SampleJet has concurrent capacity for 30 traditional chemistry samples plus 5 x 96 samples that can be stored at low temperature (typically protein samples). The system uses a standard room temperature NMR probe which gives good proton and carbon sensitivity; fluorine sensitivity on this instrument will be the highest of any instrument in the NMR Core.


This is a walkup machine which typically operates in full automation mode. Special experiments (ie longer time) need to be cleared with Walt at least a week in advance.
