Aim To investigate the possibility of determining log P via Reversed-Phase LC Introduction Increasingly, the determination of low concentrations of active ingredients in complex mixtures, sold for human consumption, has become more necessary. Regulations have imposed strict limits on the type and concentrations of a host of substances sold as foods or drugs. Such requirements demand analytical techniques that are fast and reliable and combine the separation and analysis steps in a single operation. Chromatography …

The Papp can then give us useful information for the compound in question
