pH control is very important in providing separation stability for polar organic compounds that are basic or acidic. The short-chain SB-CN column is very stable under low pH conditions (e.g. pH 2.5).

This document describes the characteristics and usage of the ZORBAX GF-250 column. The column has a wide separation range and is suitable for separating proteins with different PI and hydrophobicity.

ZORBAX SB-C18 is the most rugged, stable commercial C18 column produced by Agilent Technologies.

This file introduces StableBond short-chain bonded-phase columns from Agilent Technologies, which are much more stable than standard packings and ideal alternatives to C- 18 columns for stable reversed-phase method development.

This document introduces ZORBAX SB-CN column, including that it is the only acid-stable CN column and has unique selectivity.

This document describes a method for detecting Hypericin and provides an application example of the method.

This Application Note describes the basic principles and conditions of using Agilent ZORBAX StableBond columns to separate ulcer drugs.

This document describes the performance of Agilent ZORBAX Bonus-RP column, which has superior column efficiency and peak shape, and can be used for the determination of ulcer-treatment drugs

The document discusses the advantages of using Agilent ZORBAX Rx-SIL reversed-phase HPLC column for the separation of amines, particularly in the analysis of cough syrups. By using a reversed-phase mobile phase, the excessive retention and poor peak shape caused by the interaction of amines with unbonded silanols can be overcome. The Rx-SIL particles are stronger and more resistant to dissolution compared to xerogel silicas. This method provides the desired separation for the compounds commonly associated with cough syrups.

This document describes the features of ZORBAX Bonus-RP, including its unique selectivity and peak shape, which significantly improves resolution between peak 2 and an impurity. In addition, ZORBAX Bonus-RP is a unique polar-linked bonded phase that provides good peak shape, improved quantitation and resolution, long life over a wide pH range, and is suitable for pharmaceutical applications.

The document describes a method for high-speed separation of analgesics using smaller particles and column dimensions along with high temperature to resolve seven analgesics in less than one minute. The use of high temperature reduces run times. ZORBAX SB-C18 can operate at higher temperatures and lower pH than other commercial reversed phase columns.

This document describes a method for LSD detection using liquid chromatography-mass spectrometry. The method features rapid separation, good peak shape, and excellent sensitivity. The use of an internal standard, LAMPA, enables quantitative analysis of LSD. The method is applicable in the pharmaceutical field.

This document introduces the LC/MS detection method of LSD.

This document describes the analysis of Prazosin in serum and highlights its features and advantages in pharmaceutical applications.

The document describes a method for analyzing carbamazepine and phenytoin in plasma. The analysis is performed using online extraction and a ZORBAX SB-CN column, allowing for fast and direct analysis of these anticonvulsant drugs.
