Description

Application

CTAB may be used as a reference standard for the determination of:

• CTAB in various water samples by combining a dispersive liquid-liquid microextraction (DLLME) technique with high performance liquid chromatography.[1]
• CTAB in pharmaceutical formulations by reversed-phase high-performance liquid chromatography (RP- HPLC).[2]

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
