Laser Ablation Inductively Coupled Plasma Mass Spectrometry
New analytical techniques for multiparametric characterisation of individual cells are likely to reveal important information about the heterogeneity of immunological responses at the single-cell level. In this proof-of-principle study, laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) was applied to the problem of concurrently detecting 24 lineage and activation markers e...
متن کاملLaser Ablation Inductively Coupled Plasma
Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) is one of the most successful direct solid sampling techniques for major, minor and trace element analysis. However, this technique still suffers from matrix dependent ablation characteristics, which makes quantification very difficult. Furthermore, the laser sampled material alters its composition from the sample to the de...
متن کاملAnalyte response in laser ablation inductively coupled plasma mass spectrometry.
The dependence of analyte sensitivity and vaporization efficiency on the operating parameters of an inductively coupled plasma mass spectrometer (ICPMS) was investigated for a wide range of elements in aerosols, produced by laser ablation of silicate glass. The ion signals were recorded for different carrier gas flow rates at different plasma power for two different laser ablation systems and c...
متن کاملTime-resolved parametric studies of laser ablation using inductively coupled plasma atomic emission spectroscopy
The quantity of ablated mass and its composition strongly depend on the number of laser pulses and laser fluence at the sample target surface. For chemical analysis, thin-film deposition, cutting, and other laser-ablation applications, the quantity of mass removed vs. number of laser pulses is important. In addition, the composition of the vapor can be critical, for example, in providing accura...
متن کاملAnalysis of lead in tooth enamel by laser ablation-inductively coupled plasma-mass spectrometry.
Laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) was used to determine the Pb/Ca ratios in the enamel of deciduous incisors, a biomarker of in utero Pb exposure, using pelletized bone certified reference materials (CRMs) as calibrants. The detection limit for Pb by LA-ICP-MS was 11 microg kg(-1) demonstrating an adequate sensitivity for Pb in the teeth of unexposed indivi...
