Method Development for the Analysis of Carbonaceous Chondrites by Laser Desorption/Ionization and Secondary Ion Time-of-Flight Mass Spectrometry. [PDF]

open access: yesJ Mass Spectrom
ABSTRACT This study focuses on the development of a laser desorption/ionization mass spectrometric method for analyzing carbonaceous chondrites, meteorites that may hold clues to the origin of life. Since carbonaceous chondrites are only available in small quantities, we initially designed an artificial meteorite material (the mineral forsterite) doped
