Descripción general
Application: This column is often used for traditional general purpose applications, where a non-polar column is required. Analytes will be separated primarily according to boiling point.
USP Code: This column meets USP G1, G2, and G9 requirements.
Phase:
USP Code: This column meets USP G1, G2, and G9 requirements.
Phase:
- Bonded
- Poly(dimethyl siloxane)
- ≤0.32 mm I.D., <2 μm: -60 °C to 320 °C (isothermal or programmed)
- ≤0.32 mm I.D., ≥2 μm: -60 °C to 300 °C (isothermal or programmed)
- ≥0.53 mm I.D., <2 μm: -60 °C to 300 °C (isothermal) or 320 °C (programmed)
- ≥0.53 mm I.D., ≥2 μm: -60 °C to 260 °C (isothermal) or 280 °C (programmed)
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
SPB®-1 Capillary GC Column may be used for speciation of the nitrogen compounds (quantitatively), which are polar and somewhat basic in nature, with chemiluminescence detection.
