Carbon spectroscopy

Commercially produced barium is analyzed for metallic impurities by means of emission spectroscopy. Carbon content can be deterrnined by combustion, and nitrogen by the Kjeldahl method. Total barium can best be deterrnined gravimetricaHy by precipitation as the sulfate. [Pg.472]

Commercially produced calcium metal is analyzed for metallic impurities by emission spectroscopy. Carbon content is determined by combustion, whereas nitrogen is measured by Kjeldahl determination. [Pg.400]

Up-to-Date Treatment In addition to the classical reactions, this book covers many techniques and reactions that have more recently gained wide use among practicing chemists. Molecular-orbital theory is included early and used to explain electronic effects in conjugated and aromatic systems, pericyclic reactions, and ultraviolet spectroscopy. Carbon-13 NMR spectroscopy is treated as the routine tool it has become in most research laboratories, and the DEPT technique is included in this edition. Many of the newer... [Pg.1297]

The absence of carbonate end groups could be demonstrated by IR spectroscopy, carbonate ions would be stable in the presence of quaternary ammonium ions but not tertiary. [Pg.76]

Two further analytical methods are based on the formation of metal complexes. Reaction of dopamine with KzCrjOy gives a Cr complex which can be assayed by atomic absorption spectroscopy, carbon rod absorption spectroscopy or, if Kf CrjO has been used, by liquid scintillation spectroscopy. Since the complex still gives a reaction with fluorescamine, the side-chain is thought not to be involved in the formation of the complex. Methamphetamine hydrochloride can be precipitated as a Bi complex. Determination of the amount of Bi remaining in solution by atomic absorption spectroscopy provides an indirect method of assay for the amphetamine. ... [Pg.96]
