Descripción general

Aplicación: Esta columna se basa en una de las fases polares más utilizadas, Carbowax 20M, y es una columna polar adecuada para el análisis de disolventes, ésteres metílicos de ácidos grasos (FAME), alimentos, compuestos aromáticos y de fragancias y alcoholes. Además, esta columna es una gran opción cuando se requiere una columna polar de uso general.
Código USP: Esta columna cumple los requisitos G48 de la USP.
Fase:
  • Ligada
  • Poli(etilenglicol)
Temperatura Límites:
  • ≤D.I. 0,32 mm: de 35 °C a 280 °C (isotérmica o programada)
  • ≥0,53 mm D.I., <2 μm: de 35 °C a 280 °C (isotérmica o programada)
  • ≥0,53 mm D.I., ≥2 μm: de 35 °C a 250 °C (isotérmica o programada)

Aplicación

SUPELCOWAX 10 Capillary GC Column may be used for the analysis of milk fat in order to demonstrate its health benefits. It may also be used for high-resolution separation of polychlorinated biphenyls by comprehensive two-dimensional gas chromatography.

Structurally-tuned ionic liquids (ILs) have been previously applied as the second dimension column in comprehensive two-dimensional gas chromatography (GC×GC) and have demonstrated high selectivity in the separation of individual aliphatic hydrocarbons from other aliphatic hydrocarbons. However, the maximum operating temperatures

Comprehensive two-dimensional gas chromatography with micro electron-capture detection (GC x GC-microECD) has been evaluated for the enantioseparation of five chiral toxaphenes typically found in real-life samples (Parlar 26, 32, 40, 44 and 50). From the two enantioselective beta-cyclodextrin-based columns evaluated
