Description générale
Capillary GC column is also known as open tubular column. The carrier gas flows through the central aperture and is unrestricted throughout the length of the column.
Application : Colonne cyanosiloxane fortement polaire, couramment utilisée pour la séparation des isomères de position géométrique (cis/trans) des esters méthyliques d′acides gras (FAME) en groupe. Également utile lorsqu′il est nécessaire d′utiliser une colonne d′usage général hautement polaire avec une bonne stabilité thermique.
Code USP : Cette colonne répond aux exigences de l′USP G48.
Phase :
Code USP : Cette colonne répond aux exigences de l′USP G48.
Phase :
- Stabilisée
- Polysiloxane (90 % biscyanopropyl/10 % cyanopropylphényl)
- De sub-ambiante à 275 °C (isotherme ou programmée)
Application
- SP®-2380 Capillary Column may be used for determination of fatty acid composition in crude oil in capillary gas chromatography, used along with normal and reverse-phase high-performance liquid chromatography (HPLC) in order to study the content and composition of tocopherols, sterols, and phospholipids in soybean oils derived from genetically-modified soybeans.
- It was found suitable to be used for the identification of fatty acid methyl esters from mammalian samples by fast gas chromatography.
- It was suitable for determining the hydrogenation level and the level of isomerisation development during the hydrogenation process of edible oils by capillary gas chromatography.
- It was also suitable to be used in gas chromatography equipped with flame ionization detector (FID) for analysing the cytotoxicity of fatty acids from seed oils containing conjugated linolenic acids (CLN) on mouse tumor and human monocytic leukemia cells.
