General description

Retention Mechanism: Normal phase (charge-transfer)
Sample Matrix Compatibility: Organic solvents, oils, and lipids

  • Developed for the fractionation of FAMEs based on degree of unsaturation, and for the resolution of cis/trans isomers.
  • Silver counter-ions are anchored onto an SCX support using a proprietary procedure to offer optimal resolution, performance, and capacity
  • Each lot is tested and quality controlled for cis/trans FAME resolution
