Book Description
LA SPECTROMETRIE A DECHARGE LUMINESCENTE EST UNE TECHNIQUE DE CARACTERISATION DES SURFACES QUI FOURNIT LA REPARTITION EN PROFONDEUR DES ELEMENTS CHIMIQUES CONSTITUTIFS D'UN ECHANTILLON. SON PRINCIPE REPOSE SUR LES PHENOMENES D'EMISSION LUMINEUSE LIES AU PASSAGE D'UN COURANT ELECTRIQUE DANS UN GAZ SOUS BASSE PRESSION: LE PLASMA EST CREE PAR LA PULVERISATION DE L'ECHANTILLON PAR DES IONS ARGON. ALIMENTEE PAR UN GENERATEUR CONTINU, LA LAMPE DE GRIMM ASSURE UNIQUEMENT LA PULVERISATION DES MATERIAUX CONDUCTEURS ELECTRIQUES. EN UTILISANT UN GENERATEUR RADIOFREQUENCE ET UNE LAMPE DE GRIMM MODIFIEE, LE DOMAINE D'APPLICATION DE LA TECHNIQUE A PU ETRE ETENDU A DES ECHANTILLONS NON CONDUCTEURS. AFIN DE COMPRENDRE ET D'INTERPRETER LES RESULTATS OBTENUS AVEC CE NOUVEAU MODE RADIOFREQUENCE, IL A FALLU INSTRUMENTER LE SPECTROMETRE ET ETUDIER LES SPECIFICITES DU CIRCUIT RF AINSI CONSTITUE. CE N'EST QU'APRES UNE ETAPE DECISIVE DE FAMILIARISATION QUE LA DETERMINATION DES PARAMETRES FONDAMENTAUX QUI REGISSENT LA DECHARGE RF A PU ETRE ENVISAGEE. A CE STADE, IL A ALORS ETE POSSIBLE DE COMMENCER L'ETUDE DE LA PULVERISATION ET DE L'EMISSION LUMINEUSE EN MODE RADIOFREQUENCE. LA CONNAISSANCE DE LEURS LOIS DE VARIATION EN FONCTION DES PARAMETRES FONDAMENTAUX EST EN EFFET INDISPENSABLE SI L'ON DESIRE DEPASSER CE STADE DES RESULTATS PUREMENT QUALITATIFS. LES TRAVAUX RAPPORTES DANS CETTE THESE APPORTENT UNE CONTRIBUTION A LA COMPREHENSION DES PHENOMENES MIS EN JEU, EN VUE D'UNE APPROCHE QUANTITATIVE. POUR LE TYPE DE SPECTROMETRE UTILISE, NOUS AVONS ESSAYE DE DEDUIRE D'UNE PART UNE CONCENTRATION A PARTIR D'UNE INTENSITE LUMINEUSE ET D'AUTRE PART UNE EPAISSEUR A PARTIR D'UNE INTENSITE LUMINEUSE ET D'AUTRE PART UNE EPAISSEUR A PARTIR D'UNE DUREE DE PULVERISATION

Book Description
Glow Discharge Optical Emission Spectrometry (GD-OES) is rapidly becoming one of the most important techniques for the direct analysis of solids. This, the first book entirely devoted to the subject, represents the combined contributions of over 30 specialists from around the world. All contributors are active in the field and recognised internationally for their expertise and knowledge in GD-OES. The book begins with an introductory overview of the subjects, deals with the design of the instrument, its operation and analytical methods and describes in detail the complex plasma processes which occur inside the glow discharge source. The second part of the book is more practically orientated, showing the full range of uses for GD-OES from the bulk analysis of virtually any solid material to depth profiling within the first tens of micrometres of a variety of surfaces and coatings. Glow Discharge Optical Emission Spectrometry is intended for a wide audience of scientists, engineers and postgraduate students and will be a valuable and challenging reference work for both experienced users of the technique and newcomers alike.

Book Description
This multi-author, edited volume includes chapters which deal with both basic and highly complex applications. Glow discharge devices are now being used in very novel ways for the analysis of liquids and gases, including molecular species detection and identification, an area that was beyond the perceived scope of applicability just ten years ago. It is expected that the next decade will see a growth in the interest and application of glow discharge devices far surpassing the expectations of the last century. Responding to the rapid growth in the field Includes both GD-MS and GD-AES In-depth coverage of applications Co-edited by the top names in the field in Europe and US, with high calibre contributions from around the world

Book Description
Glow discharge optical emission spectroscopy (GDOES) is an essential technique for the direct analysis of bulk solids, for elemental surface analysis and for the depth profiling of thin films and industrial coatings. The technique has shown rapid growth in numbers of instruments, in breadth of applications, in improved quantification in recent years and is now a recognised technique within the ISO, with two international standards. Glow Discharge Optical Emission Spectroscopy: A Practical Guide takes the reader on a journey through instrument operation, sample preparation, analysis, and reporting results. It follows two sets of samples through the whole process of analysis, brass samples for bulk analysis, and zinc-coated steel for depth profiling. Procedures are consistent with recent ISO standards and each step is loaded with hands-on tips and theoretical insight. The book also includes unique data tables on spectral interferences, molecular bands, self-absorption and relative sputtering rates. This book is designed for those using or managing GDOES instruments and for students interested in learning the technique from a hands-on perspective. It is also an invaluable aid to those considering the purchase of a GDOES instrument, or those using GDOES results, to understand in detail how the technique works and what is involved in maintaining the instrument and achieving high quality results.
