[uHPLCs] USHD CN Normal Phase HPLC Column
SALE

739,600원 800,000원

The USHD CN HPLC Column features an ultra-pure silica matrix bonded with a cyanopropyl stationary phase, offering dual-mode functionality for both normal and reversed-phase chromatography.
With moderate polarity,and unique π-electron interactions, it delivers distinct selectivity, making it ideal for separating strongly basic and highly hydrophobic compounds where traditional C18 or C8 columns fall short
