title: Analysis of lipid components in zooplankter individuals by reactive pyrolysis-gas chromatography in the presence of organic alkali.
abstract: It has been eagerly requested to develop a highly-sensitive method to characterize extremely minute amounts of natural organic materials occluded in meteorites and/or space dusts in order to confirm the existence of life in the extraterrestrial space. In this article, the reactive pyrolysis-gas chromatography (Py-GC) applied to the analysis of the lipid components contained in every zooplankter individual is introduced for the sake of its potential extension to the characterization of trace amounts of the extraterrestrial organic materials. Here, Py-GC was applied to 1) the discriminative analysis among zooplankter individuals cultured in different food concentrations, and 2) the correlation analysis between the distributions of fatty acid components in the lipids of zooplankter individuals and ingested algae phytoplankton.
