NMR Concepts & Operating Techniques 07

Limited Sample Quantities & Sensitivity

   Watch Promo

When the quantity of a sample is limited, then sample handling and time averaging become important issues. Types of NMR tubes are discussed as well as the handling of NMR solvents. The fundamental principle of time-averaging is commonly used to increase the signal-to-noise ratio (S/N) of a spectrum, and the general principles of Fourier transform NMR are presented to show how they can be effectively used to perform time-averaging.

Daniel D. Traficante

Dr. Traficante obtained his Ph.D. in 1962 from MIT in the field of synthetic organic chemistry. He has worked in the NMR field since 1962, and in the early 1970s he pioneered multi-nuclear instrumentation. He has built probes, reassembled spectrometers, and developed new software programs to enhance the signal-to-noise ratio and the resolution of NMR spectra. His current research in the areas of structure determination, instrumentation, and data processing provide him with knowledge and expertise that are applicable to a broad audience. His organic chemistry background, plus his expertise in electronics, gives his lectures a special depth and appreciation for the field. Dr. Traficante is known throughout the world as an outstanding educator.
