Elemental bioimaging of Na distribution in roots ofArabidopsis thalianausing laser ablation-ICP-MS under cold plasma conditions

Abstract

Increasing soil salinity is a major problem in global crop production. The detrimental effect of saline soils on plant growth results from ionic toxicity of the Na+ ion in combination...

In situ Rb–Sr dating by collision cell, multicollection inductively-coupled plasma mass-spectrometry with pre-cell mass-filter, (CC-MC-ICPMS/MS)

“…For in situ analysis, Proteus was coupled to a Teledyne™ Photon Machines 193 nm Analyte G2™ ArF excimer laser ablation system equipped with an ARIS (aerosol rapid introduction system) 18 supplied with 0.9 l min −1 He carrier gas. A cold plasma Ni skimmer cone 19 (P/N 1341420) was used for all analyses using Proteus.…”

Laser Ablation–Inductively Coupled Plasma–Mass Spectrometry Imaging in Biology

“…52−54 Alternatively, plasmas can be operated at cool and dry conditions, where the ICP is operated at low RF power and higher nebulizer gas flows. 55,56 However, the most important method of mitigation of interferences is the CRC. 26,57 The CRC is an RF-only multipole that is situated directly before the quadrupole and reduces interferences by KED, molecular fragmentation, charge transfer, or chemical reactions to enhance selectivity for increased signal-to-noise ratios.…”

“…Interferences can partially be mitigated using gas additives to change chemical and physical processes in the plasma. Specifically, N 2 reduces ArO-based interferences and increases sensitivity. − Alternatively, plasmas can be operated at cool and dry conditions, where the ICP is operated at low RF power and higher nebulizer gas flows. , However, the most important method of mitigation of interferences is the CRC. , The CRC is an RF-only multipole that is situated directly before the quadrupole and reduces interferences by KED, molecular fragmentation, charge transfer, or chemical reactions to enhance selectivity for increased signal-to-noise ratios. While the terms collision and reaction are often used interchangeably, reaction cells typically involve a chemical reaction to remove or shift the mass of polyatomic compounds or analytes, and collision cells involve a physical process.…”

Atomic spectrometry update – a review of advances in environmental analysis

“…Studies involving elemental imaging by LA-ICP-MS included 162 a cold plasma method for studying the distribution of Na in roots of Arabidopsis thaliana grown in a cultivation medium containing 0.05 nM Na. Plasma cooling was achieved by reducing the plasma power to 670 W and delivering an additional wet aerosol (dilute HNO 3 ) to the ICP.…”
