Mass spectrometric and chromatographic techniques for determination of polycyclic compounds.

Use of the integrated ion—current technique offers great advantages over conventional mass spectrometry. It provides a most sensitive method of analysis with limits of detection in the subpicogram region. Furthermore it can be frequently used to resolve isomeric compounds. In conjunction with other techniques it offers a great potential in the detection and estimation of air pollutants. INTRODU...

Gas-chromatographic/mass-spectrometric determination of theophylline in whole blood.

We describe a combined gas-chromatographic mass-spectrometric method for determination of theophylline in whole blood. With use of a probability-based matching approach, the extensive gas-chromatographic interference did not affect mass-spectrometric quantitation of theophylline. Concentrations expected and found were linearly related from 1 to 60 mg/liter; the run-to-run coefficient of variati...

An electrospray mass spectrometric method for accurate mass determination of highly acid-sensitive phosphoramidites.

An accurate mass determination method utilizing electrospray ionization mass spectrometry is described for analysis of several different types of phosphoramidites that are extremely acid-sensitive compounds. An earlier method, which applied a LiCl/acetonitrile system, was extended for this special application by using polymeric standards including poly(ethylene glycol) (PEG), poly(ethylene glyc...
