Descripción

General description

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.

Aplicación: Una columna muy polar de cianosiloxano utilizada habitualmente para la separación de los isómeros geométricos (cis/trans) de los ésteres metílicos de los ácidos grasos (FAME) como grupo. También útil cuando se requiere una columna muy polar de uso general con buena estabilidad térmica.
Código USP: Esta columna cumple los requisitos de USP G48.
Fase:

• Estabilizada
• Poli(biscianopropil 90 %/cianopropilfenil siloxano 10 %)

Temperatura Límites:

• Subambiente a 275 °C (isotérmica o programada)

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 used for the identification of fatty acid methyl esters from mammalian samples by fast gas chromatography.
• It was used 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 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.
