Industries are adopting methods to enhance analytical performance while minimizing ecological impact. In ion chromatography, using microbore columns with diameters of 2 mm or less reduces eluent use, cutting hazardous waste and improving throughput.This note highlights rapid anion analysis in water using microbore column, which significantly reduces liquid waste compared to standard bore columns. This method enhances safety and sustainability by minimizing waste production.Both chemical and electrolytic suppression techniques are demonstrated.
The method used a Thermo Scientific™ Dionex™ IonPac™ AS23-4μm column, a Thermo Scientific™ Dionex™ AERS™ 500 Carbonate anion electrolytically regenerated suppressor, and a Thermo Scientific™ Dionex™ CRD 300 Carbonate Removal Device in vacuum mode. This work demonstrates a similar method on a Thermo Scientific™ Dionex™ Inuvion™ ion chromatography system, a new integrated, single-channel compact IC system.
This application proof note demonstrates a method for the determination of inorganic anions in municipal drinking water, which is based on the method published in Thermo Fisher Scientific Application Update 200. In this proof note, the method is performed using a new, innovative IC system that uses an electrolytic eluent generator to automatically produce eluent.
Sodium benzoate and potassium benzoate are added to acidic foods as preservatives. Therefore, benzoate is regulated as a food additive. The determinations of benzoate in liquid food products was previously demonstrated in Application Note AN165. In this application proof note, the application is demonstrated on the same column, a Thermo Scientific™ Dionex™ IonPac™ AS18 (4 × 250 mm) anion-exchange column, using eluent generation and a suppressor upgraded to current technology. The application is facilitated by the Thermo Scientific™ Dionex™ Inuvion™ ion chromatography system.
This application note describes a method for the determination of inorganic anions (fluoride, chloride, nitrite, bromide, nitrate, phosphate, and sulfate) in saturated lithium carbonate solution using a RFIC system with a Dionex IonPac AS23 column, carbonate eluent suppressor, and carbonate removal device. The method is sensitive (MDL 0.02–0.22 mg/L in saturated lithium carbonate solution), precise (RSD range 1–6%, and accurate (recovery range 95–107%).
