• CD Type: γ (gaa)
• Derivative: Butyryl
• Tep. Liits: -10 °C t 200 °C (istheral) r 220 °C (prgraed)

Incrprates a phase cnsisting f a 2,6-di-O-pentyl-3-butyryl derivative f γ-cycldextrin

This phase has shwn its best selectivity fr ain acids, certain aines and furan structures. It is a nnplar phase and has the teperature stability f the alkyl type phases. It is cnsidered a gd alternative t the bnded ain phases with uch brader separatin capabilities.

Features:

• Separates the widest variety f enantiers
• Gaa st versatile
• High selectivity fr ain acids, aines, furansTherally stable

Analytes:

Useful fr hlgus series f:

• Ain acids (priary, secndary, aratic and aliphatic)
• Aines (priary, secndary, cyclic, aratic and halgenated)
• Ain alchlsAlkanes, hydrgenated alkanes
• Alchls (aliphatic and aratic)
• Acids (halgenated and hydrxy)
• Esters (aratic, aliphatic, hydrxy, di-ester)
• DilsLactnes
• Ketnes
• Phthalides
• Sulfxides

Mechanis Observatins:

• Alkyl chain n analyte cntributes t chiral recgnitin
• High saple capacity, therefre, priary surface interactins

Size Selectivity:

Fr this derivative, gaa-cycldextrin exhibits a uch brader selectivity than beta-cycldextrin. The influence f the inclusin echanis n selectivity is uch reduced and capacities are, therefre, generally higher. -
