Amino acid analysis in micrograms of meteorite sample by nanoliquid chromatography-high-resolution mass spectrometry.

•We demonstrate amino acid analysis of Murchison meteorite using only 360 micrograms of the meteorite sample.•Nanoliquid chromatography–high-resolution mass spectrometry was used for the analyses.•Future applications could include small samples such as micrometeorites and interplanetary dust particles (IDPs).
