Chromatographic separation followed by mass spectrographs (MS) detection of test and isotopic labelled materials is generally considered to be the definitive analytical technique but is not without its dif

Our interest in ethylenediamine stems from its presence in the widely used bronchodilator drug, aminophylline, which consists of theophylline and ethylenediamine in a molar ratio of 2:1.

This is in marked contrast with the situation in HPLC where much work is done with chemically bonded phases, especially C-18 and C-8 modified silicas. Still, in recent years the widespread use of these apolar stationary phases in what

Often the detection of trace compounds requires the instrumentation to give satisfactory results at signal-to-noise ratios of below 10 at fmol levels. The ability of s
