General description
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)
SP®-2340 is a cyanopropylsiloxane stationary phase, and has high polarity and temperature resistance.
Application
Capillary column coated with SP®-2340 stationary phase may be used in gas chromatographic analysis and separation of cis/trans isomeric fatty acids.
Other Notes
We offer a variety of chromatography accessories including analytical syringes
