Digital imaging of atomization processes in electrothermal atomizers for atomic absorption spectrometry

Chakrabarti C.; Gilmutdinov A.; Hutton J. (1993)

A charge-coupled device (CCD) camera was used as the detector in an Imaging system that was constructed for the Investigation of atomizers for atomic absorption spectrometry. The two-dimensional distributions of aluminum ...
Digital imaging of formation and dissipation processes for atoms and molecules and condensed-phase species in graphite furnace atomic absorption spectrometry: A review

Hughes D.; Chakrabarti C.; Lamoureux M.; Hutton J.; Goltz D.; Sturgeon R.; Grégoire D.; Gilmutdinov A. (1996)

This is a review of our recent work in the use of a CCD-based digital imaging system for the shadow spectral digital imaging (SSDI) of boron, aluminium (spike formation), and condensation of vapour of selected analytes, ...
Kinetics of release of carbon and carbon monoxide from a graphite furnace investigated by electrothermal vaporization inductively coupled plasma mass spectrometry

Gilmutdinov A.; Staroverov A.; Grégoire D.; Sturgeon R.; Chakrabarti C. (1994)

Detection of carbon-containing molecules released during the high temperature heating of a dry, unloaded HGA-type graphite furnace (GF) has been undertaken by interfacing the GF to an ICP-MS. Desorption of O2 (as CO) ...
Mechanism of aluminium spike formation and dissipation in electrothermal atomic absorption spectrometry

Lamoureux M.; Chakrabarti C.; Hutton J.; Gilmutdinov A.; Zakharov Y.; Grégoire D. (1995)

The mechanism of aluminium spike formation and dissipation of aluminium atoms in electrothermal atomization absorption spectrometry has been investigated using two different approaches. The first approach employs a graphite ...
Three-dimensional distributions of oxygen in graphite and metal tube atomizers for analytical atomic spectrometry

Gilmutdinov A.; Chakrabarti C.; Hutton J.; Mrasov R. (1992)

A mathematical model that allows the calculation of the steady-state three-dimensional distributions of oxygen molecules inside both graphite and metal (tantalum and tungsten) tube atomizers is developed. The model takes ...
Three-dimensional modelling of the analyte dynamics in electrothermal atomizers for analytical spectrometry: influence of physical factors

Gilmutdinov A.; Mrasov R.; Somov A.; Chakrabarti C.; Hutton J. (1995)

A computer model has been developed that allows the calculation of the three-dimensional distributions of free atoms and condensed particles inside tube-type electrothermal atomizers. This model is a numerical solution of ...
