Spectrochemical elemental analysis of small liquid droplets

Abstract

The most important task of modern analytics is to gain more information from ever smaller sample quantities. A high requirement exists for analytic procedures that combine a highly specific separation process with a highly sensitive and meaningful detection system. We developed a new analytical technique combining high pressure liquid chromatography (HPLC) with laser induced breakdown spectrometry (LIBS). This enables a molecule-specific separation followed by an element-specific analysis of smallest amounts of complex samples.
