SUPELCO Astec CHIRALDEX B-DM手性气相色谱柱 毛细管柱
CD Type: β (beta)
Derivative: Dimethyl
Temp. Limits: -10 °C to 200 °C (isothermal) or 220 °C (programmed)
Incorporates a phase consisting of a 2,3-di-O-methyl-6-t-butyl silyl derivative of β-cyclodextrin. This phase exhibits broad chiral selectivity, resolving aliphatic, olefenic, and aromatic enantiomers. This particular dimethyl phase has been devised to overlap with the applications of both the PM and PH series of columns. To date, it has shown similar selectivities with shorter retention times and greater resolution. It also has exhibited thermal stability equivalent to the PM and is, therefore, the column of choice when elution temperature of the analyte exceeds 200°C. It is considered to be one of the essential columns in a GC column screening protocol.
Features:
Mechanism Observations:
Size Selectivity:
Size selectivity is evident; therefore, the inclusion mechanism is playing a role in the separation mechanism but does not dominate as it does in the DA series. The beta form as in the PH series covers a very broad range of molecular sizes and, therefore, has the greatest applicability.
Included in GC Screening Kit 71030AST.
