The Select FAME column is tuned for optimal cis/trans separations of FAMEs, especially the C18 isomers. The bonded column has an isothermal maximum operation temperature of 275°C and a programmed temperature of 290°C - a dramatic improvement of 50°C compared to non-bonded columns. Select FAME has better detection limits because the column has a very low bleed level. Even though this is a very polar column, the column efficiency is extremely high. Columns up to 200 m are available for detailed analysis of the C18:1 isomer cluster. The Select FAME column also offers three times greater loadability, further improving the shape and separation for FAME isomers - especially if one component is present at a higher concentration.
