Application Note 71 Determination of Polyphosphates Using Ion Chromatography with Suppressed Conductivity Detection INTRODUCTION EQUIPMENT Polyphosphates are used for a wide variety of industrial applications due to their sequestering and dispersing properties. Polyphosphate samples are commonly characterized by various end-group…

Application Update 172 Determination of Polyphosphates Using Ion Chromatography INTRODUCTION Dionex Application Note 71 (AN 71) demonstrates that ion chromatography (IC) using an IonPac® AS11 column set with a hydroxide eluent gradient and suppressed conductivity detection is a good technique…

Application Note 104 Analysis of Personal Care Products by Ion Chromatography INTRODUCTION Ion chromatography (IC) with conductivity detection complements traditional HPLC-UV pharmaceutical separations. IC is especially useful when the analytes do not contain chromophores, or when it is desirable to…
