M. Pietraszkiewicz et al., CALIX[4]RESORCINARENES AS DYNAMIC COATINGS FOR MODIFIED STATIONARY RP-18 PHASE FOR HPLC, Polish Journal of Chemistry, 72(8), 1998, pp. 1963-1970
Lipophilic calix[4]resorcinarenes, derived from lauryl aldehyde and re
sorcinol, are strongly adsorbed on the modified silica gel RP-18 durin
g HPLC. This technique leads to a column with an excellent time stabil
ity and good reproducibility of the retention characteristics of subst
ituted phenols as analytes.
