Generating nonlinear calibration curve using ChemStation software for analysis of topiramate with Agilent 1200 Series Ev

About this manual

Evaporative light scattering detection (ELSD) is useful for detecting and quantifying non-UV active compounds that are semivolatile or nonvolatile. The response of an ELSD to concentration is typically nonlinear, often following an exponential relationship described by the equation y = ax^b.

This study utilized Agilent ChemStation software to generate a power curve calibration, which matches the typical ELSD response equation. Topiramate was analyzed using an Agilent 1200 Series Evaporative Light Scattering Detector with an Agilent ZORBAX Eclipse XDB phenyl column.
