Descrição geral

This test mix is based on the comprehensive mix developed by Grob (Grob, et al., J. Chromatogr. 156 (1978) p. 1). It can be used to measure a column′s affinity for many analyte types:
  • The normal alkanes (decane and undecane) measure column efficiency.
  • The fatty acid methyl esters (methyl decanoate, methyl laurate, and methyl undecanoate) measure column efficiency.
  • The alcohol (1-octanol) and diol (2,3-butanediol) measure the presence of hydrogen-bonding sites (exposed silanols).
  • The aldehyde (nonanal) measures saturated aldehyde adsorption by means other than hydrogen-bonding.
  • The amine (dicyclohexylamine) measures irreversible adsorption.
  • The acid/base pair (2,6-dimethylphenol/2,6-dimethylaniline) measure acid/base surface characteristic.
  • The acid/base pair (2-ethylhexanoic acid/dicyclohexylamine) measure acid/base surface characteristic.
