TWO-STEP LASER MASS SPECTROMETRY OF TERRESTRIAL AND EXTRATERRESTRIAL MATERIALS
Amy Morrow, Hassan Sabbah

Microprobe laser-desorption laser-ionization mass spectrometry (μL2MS) is a powerful and versatile microanalytical technique that is used to study organic molecules in situ in a wide range of terrestrial and extraterrestrial materials. The combination of focused laser-assisted thermal desorption and ultrasensitive laser ionization provides sensitivity, selectivity, and spatial resolution capabilities that are unmatched by traditional methods of analysis. Over the past decade, this laboratory has developed and applied the μL2MS technique in a number of different research projects. Some areas that we are currently focusing on are:
