Analysis of natural gas - Silicon content of biomethane - Part 1: Determination of total silicon by atomic emission spectroscopy (AES) (ISO 2613-1:2023)

This document is applicable to the determination of the total silicon content in gaseous matrices such
as biomethane, biogas and landfill gas. Silicon is present in a gas phase contained predominantly in
siloxane compounds, trimethylsilane and trimethylsilanol. The analytical form of the silicon measured in
liquid phase after conducted sampling and derivatization procedure is soluble hexafluorosilicate anion
stable in slightly acidified media. Total silicon is expressed as a mass of silicon in the volume of the
analysed gas.
This document is applicable to all stated gas matrices with silicon concentrations up to 5 mg/m3, and it
is prevalently intended for the biomethane matrices containing (0,1 to 0,5) mg/m3. It can be used for
higher concentration but then the absorption efficiency of the bubblers/impingers should be checked
before the results can be regarded as valid. The detection limit of the method is estimated as 0,05
mg/m3 based on a sample volume of 0,020 m3. All compounds present in the gas phase are volatile at
the absorption and derivatization temperature and gaseous siloxanes are trapped in absorbance media
and derivatized into analytical silicon specie are measured by this method. The concentration of the
silicon is measured in diluted derivatization media using atomic emission spectrometer upon
atomisation/ionisation in microwave or inductively coupled plasma.

Analyse von Erdgas - Siliziumgehalt von Biomethan - Teil 1: Bestimmung des Gesamtsiliziumgehalts durch AES (ISO 2613-1:2023)

Dieses Dokument ist für die Messung des Gesamt Siliziumgehalts in gasförmigen Matrices wie Biomethan und Biogas anwendbar. Silizium liegt in einer Gasphase vor, die vorwiegend in Siloxanverbindungen, Trimethylsilan und Trimethylsilanol enthalten ist. Die analytische Form des in der Flüssigphase gemessenen Siliziums nach Durchführung des Probenahme  und Derivatisierungsverfahrens sind lösliche Hexafluorsilicat Anionen, die in leicht angesäuerten Medien stabil sind. Der Gesamt Siliziumgehalt wird als Masse des im analysierten Gasvolumen vorhandenen Siliziums angegeben.
Dieses Dokument ist für festgelegte gasförmige Matrices mit Siliziumkonzentrationen bis 5 mg/m3 anwendbar, und ist vorwiegend für die Biomethan Matrices mit einer Si-Massenkonzentration von 0,1 mg/m3 bis 0,5 mg/m3 Si vorgesehen.
Mit einer Anpassung zur Sicherstellung eines angemessenen Absorptionsgrades kann es auch für höhere Konzentrationen angewendet werden. Die Nachweisgrenze des Verfahrens wird auf 0,05 mg/m3 abgeschätzt, basierend auf einem Gasprobenvolumen von 0,020 m3. Alle Verbindungen, die in der Gasphase vorliegen, sind bei der Absorptions  und Derivatisierungstemperatur flüchtig, und gasförmige Siloxane werden in Absorptionsmedien eingefangen und in eine analytische Form von Silizium derivatisiert, welche mit diesem Verfahren gemessen wird. Die Siliziumkonzentration wird in verdünnten Derivatisierungsmitteln mittels Atomemissionsspektrometrie mit Atomisierung/Ionisation in Mikrowellen  oder induktiv gekoppeltem Plasma gemessen.
Sofern nicht angegeben, beziehen sich alle Volumina und Konzentrationen auf Normbedingungen (Temperatur, 273 K, und Druck, 101,325 kPa).
ANMERKUNG   Bei Anwendung geeigneter Verdünnungsfaktoren kann das Verfahren auch für Siliziumkonzentrationen über 5 mg/m3 angewendet werden.

Analyse du gaz naturel - Teneur en silicium du biométhane - Partie 1: Détermination de la teneur totale en silicium par spectrométrie d’émission atomique (SEA) (ISO 2613-1:2023)

Le présent document s'applique à la mesure de la teneur en silicium total dans des matrices gazeuses telles que le biométhane et le biogaz. Le silicium est présent sous forme gazeuse, et contenu principalement dans des composés de siloxane, le triméthylsilane et le triméthylsilanol. La forme analytique du silicium mesurée dans la phase liquide après échantillonnage et dérivatisation, est un anion hexafluorosilicate soluble stable dans les milieux légèrement acidifiés. Le silicium total est exprimé sous la forme d'une masse de silicium dans le volume du gaz analysé.
Le présent document s'applique aux matrices gazeuses énoncées, avec des concentrations de silicium allant jusqu'à 5 mg/m3, et concerne principalement les matrices de biométhane avec une teneur en silicium comprise entre 0,1 mg/m3 et 0,5 mg/m3.
Avec une adaptation assurant une efficacité d'absorption appropriée, il peut être utilisé pour des concentrations plus élevées. La limite de détection de cette méthode est estimée à 0,05 mg/m3 pour un volume d'échantillon de gaz de 0,020 m3. Tous les composés présents dans la phase gazeuse sont volatils à la température d'absorption et de dérivatisation, et les composés organosiliciés gazeux sont piégés dans le milieu d'absorption puis dérivés sous forme de silicium analytique qui est mesuré selon la présente méthode. La concentration de silicium est mesurée dans le milieu de dérivatisation dilué, par spectrométrie d'émission atomique, après atomisation/ionisation dans un plasma micro-ondes ou à couplage inductif.
Sauf indication contraire, tous les volumes et concentrations sont établis pour des conditions normales (température, 273 K et pression, 101,325 kPa).
NOTE            Avec des facteurs de dilution appropriés, la méthode peut également être appliquée à des concentrations de silicium supérieures à 5 mg/m3.

Analiza zemeljskega plina - Vsebnost silicija v biometanu - 1. del: Določevanje celotnega silicija z atomsko emisijsko spektroskopijo (AES) (ISO 2613-1:2023)

Ta dokument se uporablja za določevanje celotnega silicija v plinastih matricah, kot so biometan, bioplin in deponijski plin. Silicij je prisoten v plinski fazi predvsem siloksanovih spojin, trimetilsilana in trimetilsilanola. Analitična oblika silicija, izmerjena v tekoči fazi po izvedenem vzorčenju in postopku derivatizacije, je topni heksafluorosilikatni anion, stabilen v rahlo kislem mediju. Celotni silicij je izražen kot masa silicija v prostornini analiziranega plina.
Ta dokument se uporablja za vse navedene plinaste matrice s koncentracijami silicija do 5 mg/m3 in je pretežno namenjen za matrice biometana z vsebnostjo 0,1 do 0,5 mg/m3. Uporabiti ga je mogoče za višje koncentracije, vendar je v tem primeru priporočljivo preveriti absorpcijsko učinkovitost enot za ustvarjanje mehurčkov/zbiralnikov plinov, preden je mogoče potrditi veljavnost rezultatov. Meja zaznavnosti pri tej metodi je ocenjena na 0,05 mg/m3 na podlagi prostornine vzorca 0,020 m3. Ta metoda se uporablja za merjenje vseh zmesi, prisotnih v plinasti fazi, ki so hlapne pri temperaturi absorpcije in derivatizacije, ter plinastih siloksanov, ujetih v absorpcijskem mediju in derivatiziranih v vrsto analitičnega silicija. Koncentracija silicija se izmeri v razredčenem mediju za derivatizacijo z atomskim emisijskim spektrometrom po atomizaciji/ionizaciji v mikrovalovni plazmi ali induktivno sklopljeni plazmi.
