The analytical potential of a nanosecond laser ablation inductively coupled plasma mass spectrometer system, equipped with an ultra-fast wash-out chamber, is critically investigated for fast and highly spatially resolved (∼μm) qualitative elemental distribution within single cells.
The on-line coupling of vesicle-mediated high-performance liquid chromatography (HPLC) to low-power argon microwave-induced plasma (MIP) detection is described. analytical potential such a hybrid technique illustrated for the speciation mercury and arsenic compounds. Continuous cold vapour (CV) or hydride generation (HG) techniques were used as interfaces between exit HPLC column MIP, held in surfatron at reduced pressure. Detection was by atomic emission spectrometry (AES). effect different...
Direct solid analysis of bulk and thin coated glasses by pulsed radiofrequency (rf) glow discharge time-of-flight mass spectrometry (GD-TOFMS) is investigated. Modulated low pressure plasma created pulsed-rf-GD has been coupled to a fast TOFMS in order obtain complete spectra information from the different GD pulse domains (pre-peak, plateau afterglow). In particular, it was observed that analytes show highest atomic ion signals afterglow region some hundred microseconds after maximum Ar...
The application of a new methodology for direct solid analysis fluorine by LIBS is evaluated. This approach, based on the nebulization Ca solution over fluorine-containing sample, allows F quantification using emission CaF molecular bands.

The analytical potential of a radiofrequency glow discharge orthogonal time-of-flight mass spectrometer (RFGD-TOFMS) has been evaluated in both pulsed and non-pulsed modes. A certified reference steel was selected for this study. operating conditions the GD plasma (pressure applied power) were optimized terms sensitivity. Additionally, duty cycle pulse width parameters investigated RF mode. In case, high analyte ion signals improved signal to background ratios measured after end pulse,...

A plasma cleaning procedure to improve elemental depth profiling of shallow layered materials by glow discharge spectrometry is proposed. The based on two approaches applied prior profiling, either individually or sequentially. first approach employs a generated at low power, i.e. "soft" plasma, for removal contaminants adsorbed the surface target material. In second approach, sacrificial material sputtered under normal conditions, e.g. those used clean inner anode source. It demonstrated...
Abstract We demonstrate the potential of an innovative technique, pulsed radiofrequency glow discharge time‐of‐flight mass spectrometry, for molecular depth profiling polymer materials. The technique benefits from presence, in afterglow discharge, fragment ions that can be related to structures polymers under study. Thin films different (PMMA, PET, PAMS, PS) were successfully profiled with retention information along profile. Multilayered above also profiled, and it was possible discriminate...
