October 12, 2005
Author(s)
CCQM OAWG, Michele M. Schantz, David L. Duewer, Willie E. May, Reenie M. Parris, Stephen Wise
Solutions of known mass fraction of organic analytes of interest are typically used to calibrate the measurement processes used in the determination of these analytes. Appropriate value assignments and uncertainty calculations for these calibration

Anzor I. Mikaia, Vladimir Smetanin, Vladimir G. Zaikin, Alla V. Antonova, Nikolay A. Prostakov
A GC-MS method is developed for structure determination of aliphatic within mixtures. It involves online application of a gas-phase dehydrogenation reaction after GC separation and before MS analysis. Primary and secondary alcohols are converted into

Infrared and Raman Spectroscopy Characterization of Biological Products

January 1, 2005
Author(s)
Vytautas Reipa
Both infrared and Raman are increasingly applied in biomolecular structure characterization, thus getting acceptance alongside traditional bioanalytical techniques. Physical principles and biological sampling requirements are reviewed. Advanced
