This application note demonstrates how Massbox® brings high-sensitivity elemental mapping to environments where conventional laboratory instruments cannot operate.
Instruments capable of creating high-sensitivity maps are traditionally confined to centralized laboratories, requiring researchers to ship samples from the field and wait for results. For certain extreme environments, in-situ analysis is not just preferable but necessary.
Using LALI-TOF-MS, Massbox directly analyzes particles and biogenic material with high sensitivity and reduced spectral interferences. Carbon, nitrogen, and phosphorus indicate biological activity, while aluminum, silicon, and titanium are typical of abiotic materials, allowing elemental maps to discriminate between organic and inorganic material. Because each laser spot contains a full mass spectrum, results are not limited to pre-specified elements.
This proof-of-concept study used a transparent planar crystal of gypsum as an analog for extraterrestrial ice, with diluted solutions of lunar simulant, pollen, and a non-pathogenic bacterium deposited on the substrate.
In a single analytical session of approximately 10 minutes, Massbox produced elemental maps that clearly distinguished biological deposits from mineral regolith.
Massbox requires only single-phase power and basic room temperature control, with no argon gas, fume hoods, or hazardous chemicals needed.
