The method utilizes HPSEC instrument with the following conditions: column: DuPont HPLC ZORBAX PSM 60S, 6.2 mm x 25 cm (Agilent P/N: 880957-802); mobile phase: tetrahydrofuran; flow rate: 1.5 mL/min; temperature: 22°C; detector: UV Abs (254 nm); sample: Epon 836.
Agilent Surfactants - TX-114
The document introduces a stable C18 column that can be used for high temperature separation of low molecular weight polymers
Agilent Technologies Antihistamines - Excellent Resolution of Drug Mixtures
This document describes the features of ZORBAX StableBond C8, which has a sterically protected bonded phase that allows stable operation at low mobile-phase pH. ZORBAX SB-C8 separates basic compounds with good resolution and peak shape using simple mobile phases. The document also provides the conditions for using ZORBAX Rx/SB-C8 in pharmaceutical applications.
Agilent Technologies Opiate Drugs - Basic Compounds Show Good Peak Shape on Rx-Silica
This document describes that Agilent Technologies' Rx-Silica highlights good peak shape of basic compounds in opiate drugs. These basic compounds have poor peak shape on many reversed-phase columns. ZORBAX Rx-SIL has an extremely homogeneous silica surface with uniform associated silanols and low acidity. ZORBAX Rx and StableBond columns show significantly reduced band tailing and improved column efficiency when analyzing basic compounds.
