From the fundamental Matthieu equations which described the movement of ions in quadropole field, stability criteria are derived for the transmission of ions with precisely defined mass-to-charge ratio (M/e) through the spectrometer. Based on the understanding of the QMS principles, two models of operation are described: by contrast resolution M/triangleM and by constant triangleM, with an emphasis on advantages and disadvantages of respective modes. The construction of modern spectrometers is briefly presented, including ionization chamber, ion optics and counter electronics. Two typical examples of mass spectrometry of plasma are also given</dc:description><dc:description xml:lang="sl">Podan je opis kvadrupolnega masnega spektrometra (QMS), ključnega elementa energijsko ločljive masne spektroskopije plazme in rezidualnih plinov. Iz osnovnih Mathieuevih enačb, ki opisujejo gibanje iona v kvadrupolnem polju so izvedeni stabilnostni pogoji, pri katerih spektrometer prepušča ione s točno določenim razmerjem med maso iona M in nabojem e, tj. M/e. Na osnovi razumevanja delovanja QMS sta razložena načina delovanja s konstantno resolucijo M/trikotnikM in konstantnim trikotnikM s poudarkom na dobrih in slabih straneh posameznega načina meritve. Na kratko je prikazana tudi izvedba sodobnih spektrometrov od ionizacijske celice oziroma ionske optike do števne elektronike. Podana sta še dva značilna primera uporabe masne spektroskopije plasme</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-GXFEFBIL"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-GXFEFBIL" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-GXFEFBIL/523bf280-ebaf-4655-8415-ff5b8034caa2/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Društvo za vakuumsko tehniko Slovenije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-GXFEFBIL/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-GXFEFBIL" /></ore:Aggregation></rdf:RDF>
