    Ready-to-Use HPLC Applications

Simultaneous specific determination of six antihistamine drugs using isocratic HPLC-UV

Document #022920-02. Revision 01, 29 February 2020

 

Analytes 

Cetirizine, Chloropyramine, Chlorpheniramine, Pheniramine, Desloratadine, Doxylamine.

Scope of The Method

The method is intended for the highly selective determination of six antihistamine drugs (cetirizine, chloropyramine, chlorpheniramine, pheniramine, desloratadine, doxylamine) in various pharmaceutical and biological samples using simple isocratic 400 bar HPLC system with a conventional UV detector.
       The method is capable to determine antihistamines in complex matrices that contain any neutral or acidic matrix compounds, as well as various basic compounds like drotaverine, dextromethorphan, phenylephrine, etc.
      The method is not capable of determining loratadine.

Minimum System Requirements
Solvent Delivery System: Isocratic HPLC pump with 400 bar upper back-pressure limit 
Detector: Single wavelength UV detector
Column Oven: Preferable to ensure retention time stability

Compartible with all HPLC systems: Agilent, Shimadzu, Waters, Thermo, etc.

General Information On The Method
Elution Mode: isocratic,  Detection: UV, Actual Analysis Time: 6.5 minutes at 1.5 mL/min, Back-pressure: typically < 300 bar at 1.5 mL/min, HPLC column manufacturer: Advanced Chromatography Technologies, Scotland >>
