Agilent J&W CP-Select 624 己烷专用柱可实现溶剂和己烷

The Agilent J&W CP-Select 624 Hexane GC column, with an optimized G43 stationary phase, separates dichloromethane (DCM) from hexane isomers. This application note shows the separation as applied by pharmaceutical and food processing industries in India. Each column is tested with a special test mix that guarantees good column-to-column reproducibility. As with the specific separation of DCM, the USP <467> specification for the separation of acetonitrile and dichloromethane is in compliance, and tested for in every batch of stationary phase. Column selectivity is compared for two series using a multicomponent mix against two columns from another vendor. Agilent 5977B 单四极杆气质联用系统GC/MSD
