Abstract:
A set of 17,600 samples belonging to our compound collection is selectively examined by liquid chromatography with UV, evaporative light scattering, and mass spectrometric detection methods. At least 70% of this set consists of pure samples with the expected structures. Subsequent studies by flow injection mass spectrometry show that this value is a conservative estimate and that the actual percentage of pure and correct compounds is close to 80%. Because this is the first time that sample quality information becomes available on such a large scale for the compound collection, it offers an opportunity to perform chemi-informatic studies for which structural integrity is essential. Results of these studies can be used to improve the selection of compounds for screening and evaluate the quality of compounds from particular sources.

Chromatography: Introduction
The phase in which the compounds linger or on which the compounds adsorb is called the stationary phase, whereas the mobile phase is the solvent that carries the solutes to be analyzed. In traditional column chromatography, the mixture flows through the stationary phase, and the compounds partition between the stationary and mobile phases...
