Astec CHIRALDEX B-PM SUPELCO 手性氣相色譜柱 毛細(xì)管柱

• CD Type: β (beta)
• Derivative: Perethylated (all available -OH grups ethylated)
• Tep. Liits: -10 °C t 200 °C (istheral) r 220 °C (prgraed)

Incrprates a phase cnsisting f a 2,3,6-tri-O-ethyl derivative f β-cycldextrin. This phase exhibits brad chiral selectivity and is gd fr terpenes and tertiary aines.

The perethylated beta-cycldextrin is a statinary phase that has indicated a ptential t separate a wide variety f raceates. Many f thse separatins are better reslved n ther CHIRALDEX phases based n lwer retentin, better selectivity and greater efficiency. What the PM des especially well are se hydrcarbns like terpenes, certain underivatized alchls and dils and se analytes with plar grups like tertiary aines.

Features:

• Brad chiral selectivity
• Strng inclusin/size selectivity
• Beta st selective f cycldextrins

Mechanis Observatins:

• Inclusin a dinant echanis
• Highest teperature stability f CHIRALDEX phases alng with the DM

Size Selectivity:

Se size selectivity is evident with the perethylated phase. The beta fr will cver a brad range f lecule sizes.
