Gas Chromatography-Mass Spectroscopy
Gas chromatography-mass spectroscopy (GC-MS) is one of the so-called hyphenated analytical techniques. As the name implies, it is actually two techniques that are combined to form a single method of analyzing mixtures of chemicals. Gas chromatography separates the components of a mixture and mass spectroscopy characterizes each of the components individually. By combining the two techniques, an...
متن کاملTitle: Degradation Kinetics of Taxol Using Mass Spectroscopy Degradation Kinetics of Taxol Using Mass Spectroscopy
Approved: Paclitaxel is a very important anticancer drug commonly called Taxol ®. We know from previous work (Hoffman, et al., 1998) that Taxol exists in filbert, Corylus avellana L. material. Quantification of Taxol in filbert plant material is painstaking and hitherto was accomplished by rapidly processing single batches in a complicated procedure (Hoffman, et al., 1998), which seemingly unav...
متن کاملMass Spectroscopy Using Single Ion Cyclotron Resonance
An inhomogeneous radio fquency electric field can couple the cyclotron and axid modes of a single icn in a Penning trap. The classical equations of motion are the same as those of a driven quantum mechanical two-level system. We discuss an analog of the A-pulse, which can exchange mode actions, and an analog of avoided crossing. Experimental illustrations are presented. PACS: 07.75.+h, 46.10.+z...
متن کاملHeavy Quark-meson Mass Gap from Spectroscopy
Using a quite accurate flavour-independence of nS-level mass differences in heavy quarkonia and a corresponding quasiclassical expression for the heavy quark binding energy, one shows that experimental data on masses of mesons with heavy quarks allow one to make the estimate ¯ Λ = 0.63 ± 0.03 GeV.
متن کاملCavity ringdown laser absorption spectroscopy and time-of-flight mass spectroscopy of jet-cooled copper silicides
The cavity ringdown technique has been implemented for electronic spectroscopy of jet-cooled CuSi produced in a pulsed UV laser vaporization plasma reactor. A time-of-flight mass spectrometer is used to simultaneously monitor species produced in the supersonic expansion and allows correlation studies to be performed. Seven rotationally resolved vibronic bands have been measured near 400 nm, yie...
