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. SP®-2340 is a cyanopropylsiloxane stationary phase, and has high polarity and temperature resistance.
Application: This non-bonded column offers the highest polarity in its class. As with all general purpose biscyanopropyl columns, it is highly effective for both high and low temperature separations of geometric isomers of fatty acid methyl esters (FAMEs), dioxins, carbohydrates, and aromatic compounds.
USP Code: This column meets USP G5 requirements.
Phase:
USP Code: This column meets USP G5 requirements.
Phase:
- Non-bonded
- Poly(biscyanopropyl siloxane)
- Subambient to 250 °C (isothermal or programmed)
Application
Capillary column coated with SP®-2340 stationary phase may be used in gas chromatographic analysis and separation of cis/trans isomeric fatty acids.
