✦ Synopsis

A new approach to on-line oxygen isotope analysis has been developed which utilises existing elemental analyser and mass spectrometry technology to produce a sample of carbon dioxide gas for oxygen isotople analysis. The method relies on on-line high temperature pyrolysis of the sample over a carbon source followed by a rapid, non-contributive partial catalytic oxidation over nickel powder at between 550 and 600 degrees C. Initial results demonstrate both good precision (better than 0.2 per thousand) and accuracy for both cellulose and silver nitrate samples. Copyright 1999 John Wiley & Sons, Ltd.

A procedure that permits rapid development of an optimized solid phase extraction (SPE) method for the analysis of drugs in plasma by on-line solid phase extraction-mass spectrometry (SPE-MS) has been developed. This procedure employs the concept of manipulating the pH and the percentage of organic
