Nuclear Magnetic Resonance (NMR) spectroscopy is an analytical chemistry technique used in quality control and reserach for determining the content and purity of a sample as well as its molecular structure. For example, NMR can quantitatively analyze mixtures containing known compounds. For unknown compounds, NMR can either be used to match against spectral libraries or to infer the basic structure directly. Once the basic structure is known, NMR can be used to determine molecular conformation in solution as well as studying physical properties at the molecular level such as conformational exchange, phase changes, solubility, and diffusion. In order to achieve the desired results, a variety of NMR techniques are available. The basics of NMR are described here. You too can do NMR by using our NMR service.
Our laboratory is an analytical unit, which provides Elemental Analysis and LCMS Analysis service for universities, chemical and pharmaceutical companies, research and industrial foundations. We perform the following evaluations: analysis of C, H, N and O, the halogens: Cl,Br,I,F and S,P, all in a broad spectrum of samples, (for example, synthesized organic compounds, natural products, coal and coal derived materials, pharmaceutical, industrial samples and others), High resolution mass determination, detection and separation in a wide range of polar masses such as: small molecules, proteins, peptides and oligonucleotides.
The Laboratory for Molecular Structure Analysis was established in 1979 within the Institute of Chemistry in order to serve researchers from inside and outside the Institute in all aspects of X-ray crystallography. The laboratory is equipped with three Single- crystal X-ray Diffractometers and one Powder X-ray Diffractometer. Dr. Shmuel Cohen is our experienced staff crystallographer and the unit is supervised academically by Prof. Avi Bino.
Services include complete three dimensional molecular structure elucidation both at low and room temperature, comprehensive computerized data bases search, unit-cell dimensions determination, powder diffraction and simulations of powder diffraction patterns. The unit also provides consulting services on X-ray diffraction, sampling, diffraction data collection strategies, powder diffraction data acquisition and data analysis.
A modern and efficient infrastructure to support the communication network, electronics and computing needs within the Institute of Chemistry. Our staff is very experienced with scientific equipment troubleshooting, and developing new hardware for it. We administrate three UNIX machines that help our users in mail, graphics, file and web servers in addition to two novel servers that aid our users with file, programs and backups. We also have been developing advanced programming methods helping us control and acquire data from diverse range of equipment.
