The signal dependence on the delay between the two laser pulses shows an enhanced si...

a r t i c l e i n f o Keywords: Calibration free laser-induced breakdown spectroscopy (CF-LIBS) Multi-element analysis Oxides The quantitative determination of oxide concentration by laser-induced breakdown spectroscopy is relevant in various fields of applications (e.g.: analysis of ores, concrete, slag). Calibration free laser-induced breakdown spectroscopy and the multivariate calibration ar...

The murine monoclonal antiplatelet antibodies MA-TSPI-1 (directed against human thrombospondin) and MA-PMI-2, MA-PMI-1, and MA-LIBS-1 (directed against ligand-induced binding sites [LIBS] on human platelet glycoprotein IIb/IIIa) were conjugated with recombinant single-chain urokinase-type plasminogen activator (rscu-PA) using the cross-linking reagent N-succinimidyl 3-(2-pyridyldithio)propionat...

Laser-induced Breakdown Spectroscopy (LIBS) is a highly sensitive technique for elemental analysis that can be used to obtain temporally and spatially resolved atomic species concentrations in combustion systems. In this paper LIBS is employed to quantify equivalence ratios in laminar premixed methane-air flames. A microplasma is generated by a pulsed Nd:YAG laser with pulse duration 5 ns opera...

Introduction: Laser-induced Breakdown spectroscopy (LIBS) is currently under development for future lander missions to Mars [1–10] and other planets and moons, like Venus or Europa [11, 12]. LIBS spectroscopically determines the visible atomic emission from a plasma that is generated by pulsed laser light focused on a sample surface. The intensities of the many characteristic spectral lines of ...

Aerosols play an important role in the atmosphere but are poorly characterized, particularly in urban areas like the Mexico City Metropolitan Area (MCMA). The chemical composition of urban particles must be known to assess their effects on the environment, and specific particulate emissions sources should be identified to establish effective pollution control standards. For these reasons, sampl...

For several years, the specific features of PIXE and PIGE have made them very attractive in the field of archaeometry. Among them, non-destructivity is one of the most important. The possibility of working under atmospheric pressure is also important because of the very different shapes and sizes of the artefacts concerned. However, these ion beam techniques suffer from the same disadvantage: t...

Forensic anthropologists use various methods to determine the type of weapons used in cases involving a dismembered body. For this study PIXE (particle-induced x-ray emission) analysis was performed on samples taken from pieces of pig bone cut with three different hacksaw blades. The analysis was used to determine if the blades left any elemental residue on the bone. When the results of the PIX...

Introduction: The elemental composition of rocks and soils is one of the most fundamental types of information needed to understand geologic contexts and to search for likely locations of biological activity. Nearly all methods for determining elemental composition involve in-situ analysis, requiring time-consuming maneuvering of a rover to acquire the desired sample. By contrast, analyses at s...
