Simultaneous Determination of Positive and Negative Counterions Using a Hydrophilic Interaction Chromatography Method
The authors work to develop a universal high performance liquid chromatography method that is capable of simultaneously retaining and separating both cations and anions within a single chromatographic analysis for the purpose of quantification in pharmaceutical products.
Comparison of an Evaporative Light-Scattering Detector and a Chemiluminescent Nitrogen Detector for Analyzing Compounds Lacking a Sufficient UV Chromophore
The authors discuss the advantages and disadvantages of evaporative light-scattering detection and chemiluminescent nitrogen detection for determining compounds lacking UV chromophores.
Analysis of Weak UV-Absorbing Pharmaceutical Drug Substances Using CE with Condensation Nucleation Light-Scattering Detection
The authors descibe the use of CE with condensation nucleation light-scattering detection to analyze three pharmaceutical analytes. Because the compounds lack adequate UV chromophores, they require a more sensitive means of detection.
