SAMPLE PREPARATION LABORATORY
SAMPLE PREPARATION LABORATORY
The Sample Preparation Laboratory is designated for preparation of analog samples to match the wide range of analysis techniques possible in the lab.
This includes selection of grain size fractions as well as pressed pellets and equilibrium adsorption of organic molecules on mineral matrix with several tecniques. Samples are characterize before and after preparation using several techniques.
A strict cleaning protocol in applied to sample preparation to ensure a contamination free process.
MULTI-ANALYSIS LABORATORY
MULTI-ANALYSIS LABORATORY
The Multi-Analysis Laboratory regroup all the analytical instruments of the Arcetri Astrobiology Lab. Several instruments are hosted in the lab to perform infrared and Raman spectroscopy, UV spectrophotometry, liquid chromatography and mass spectroscopy. The laboratory facility can simulate space relevant environment through thermal control from cryogenic to high temperatures and UV and ions in-situ irradiation.
