Applicability of Standardless Semiquantitative Analysis of Solids by High-Irradiance Laser Ionization Orthogonal Time-of-Fight Mass Spectrometry

Abstract: A compact high-irradiance laser ionization time-of-flight mass spectrometry system has been developed for the multielemental analysis of solids. Helium was introduced into the ion source as a buffer gas to cool high kinetic energy ions and suppress the interference of multicharged ions. A special pulse train repelling mode was used to achieve explicit spectra. Two quantitative methods are described for the laser ionization mass spectrometry in this paper. The first of these is the routine calibration curve qua… Show more

“…Different methods such as chemical interaction have been developed to analyze volatile metabolites and to compare them in healthy subjects and cancer patients, adsorptive binding, cold trapping and supercritical fluid extraction. The most successful in this field are SPME and the recently developed multi-bed sorption trap [23][24][25]. The SPME technique was developed by Pawliszyn in late 1989 as a new preconcentration technology, in which a fused coated silica fiber is used as the stationary phase [20,26].…”

“…the elements, [14,17] which together with the ability of clean material ablation [19][20][21][22] and high pulse-to-pulse reproducibility enable a laser ablation in a highly controlled manner. [4,17] So far, various LIMS systems have been designed and constructed specifically to investigate different scientific questions and for the application in variable environments, ranging from elemental mapping [8,23] to depth profiling analyses, [4,16] from laboratory [7,8,12,[14][15][16]24,25] instruments to instruments with the capability to operate on planetary objects. [17,[26][27][28][29][30][31] However, and to our best current knowledge, only the designs from the research groups of Huang, [8,14,15,24] Cui et al, [16] and Wurz, [4,13,17,23,32] have reached the measurement capabilities and performance comparable to the state-of-the-art measurement techniques for chemical analysis with high spatial resolution.…”

“…All these systems consist of a TOF mass analyser, a sophisticated detector system and are equipped with a femtosecond laser ablation/ionisation source and differ only in their technical realisation. In the following the LIMS systems from Cui et al [16] and the Huang group [8,14,15,24] are discussed only briefly. Readers should consult the listed references for further information.…”
