Descripción

General description

Aplicación: Esta columna no polar de uso general proporciona principalmente un orden de elución por punto de ebullición con un ligero aumento en la selectividad, en especial para los compuestos aromáticos.
Código USP: Esta columna cumple los requisitos G27 y G36 de la USP .
Fase:

• Ligada
• Poli(difenil al 5 %/dimetil siloxano al 95 %)

Temperatura Límites:

• ≤0,32 mm D.I., <2 μm: de -60 °C a 320 °C (isotérmica o programada)
• ≤0,32 mm D.I., ≥2 μm: de -60 °C a 300 °C (isotérmica o programada)
• ≥0,53 mm D.I., <2 μm: de -60 °C a 300 °C (isotérmica ) o 320 °C (programada)

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

SPB^®-5 Capillary GC Column was used for speciation of the nitrogen compounds (quantitatively), which are polar and basic in nature, with chemiluminescence detection. It may be used as stationary phase for determination of nivalenol and deoxynivalenol in cereals by electron-capture gas chromatography. It may also find application in being used as stationary phase in capillary column gas chromatography for determination of sterols.
