Integrated Laboratory & Research Center Universitas Indonesia – Nuclear Magnetic Resonance Laboratory (ILRC UI-NMR) provides a reliable instrument for analyzing chemical information of liquid sample using NMR spectroscopy. NMR is information rich, non-destructive analytical technique. NMR Laboratory Application Procedures: 1. Users must first complete the ‘NMR Application’ form located on the page of Bruker Ascend 500 - NMR Spectroscopy. 2. Users will receive a confirmation email stating that the user can bring the sample to the Lab B (ILRC Building - 3rd floor). 3. Users must provide samples to Laboratory staff along with explanations of the samples. Regardless of hazard level of the sample, every user should be prepared to discuss the risk classification for the material of the sample. Hazardous material cannot be brought into ILRC Lab (even if frozen) without prior approval from laboratory staff. 4. User submits a request letter from the faculty and research proposal.
