“…They established that ns pulses were inadequate to assess the polymer coating on an Al-Mg substrate because of their weak absorption, while fs pulses yielded well-resolved proles with a depth resolution of 1 mm. More recently, de Bonis et al 100 compared 40 ns pulses vs. 40 fs pulses to measure the depth of a patina to clean corroded bronzes. Because the ablation rate of a 40 ns laser was four times larger than that for a 40 fs laser, the resolution of femtosecond LIBS depth proling was better and accuracy with respect to the Cu/Sn ratio was also better due to minimal fractionation.…”

“…Moreover there are several advantages in using fs-LA for LIBS and LA-ICP-MS over ns-LA, which include reduced continuum emission, better Paper control of ablation efficiency, particle distribution, elemental fractionation and matrix dependence. The differences in nsand fs-LA are documented in the literature for both LIBS 19,20,26 and LA-ICP-MS 3,6,27,28 applications.…”

“…In analytical measurement techniques that involve laser ablation ion sources, for example, laser-induced breakdown spectroscopy (LIBS), laser ablation ionization mass spectrometry (LIMS), or laser ablation inductively coupled mass spectrometry (LA-ICP-MS), shot-to-shot signal variations are expected (e.g., Cui et al, 2012;De Bonis et al, 2014;Gutierrez-Gonzalez et al, 2015). Such variations may arise from various factors, including instability of the used laser system, sample morphology and porosity (voids), and local variations in chemical composition.…”

The detection and identification of biosignatures on planetary bodies such as Mars in situ is extremely challenging. Current knowledge from space exploration missions suggests that a suite of complementary instruments is required in situ for a successful identification of past or present life. For future exploration missions, new and innovative instrumentation capable of high spatial resolution chemical (elemental and isotope) analysis of solids with improved measurement capabilities is of considerable interest because a multitude of potential signatures of extinct or extant life have dimensions on the micrometer scale. The aim of this study is to extend the current measurement capabilities of a miniature laser ablation ionization mass spectrometer (LIMS) designed for space exploration missions to detect signatures of microbial life. In total, 14 martian mudstone analogue samples were investigated regarding their elemental composition. Half the samples were artificially inoculated with a low number density of microbes, and half were used as abiotic controls. The samples were treated in a number of ways. Some were cultured anaerobically and some aerobically; some abiotic samples were incubated with water, and some remained dry. Some of the samples were exposed to a large dose of g radiation, and some were left un-irradiated. While no significant elemental differences were observed between the applied sample treatments, the instrument showed the capability to detect biogenic element signatures of the inoculated microbes by monitoring biologically relevant elements, such as hydrogen, carbon, sulfur, iron, and so on. When an enrichment in carbon was measured in the samples but no simultaneous increase in other biologically relevant elements was detected, it suggests, for example, a carbon-containing inclusion; when the enrichment was in carbon and in bio-relevant elements, it suggests the presences of microbes. This study presents first results on the detection of biogenic element patterns of microbial life using a miniature LIMS system designed for space exploration missions.
