This application note demonstrates that AOX can be precisely and accurately determined in wastewater using combustion ion chromatography. Analysis was automated using the Mitsubishi AQF–2100H system in combination with the Dionex Integrion HPIC system with a Dionex IonPac AS18-4μm column.

To demonstrate that oxyhalides and bromide can be successfully determined at concentrations required for regulatory standards and guidelines using a Thermo Scientific™ Dionex™ ion chromatography system equipped with a Thermo Scientific™ Dionex™ IonPac™ AS23-4μm column,Thermo Scientific™ Dionex™ CRD 300 Carbonate Removal Device, and a Thermo Scientific™ Dionex™ AERS™ 500 Carbonate Anion Electrolytically Regenerated Suppressor.

Tobramycin is an important aminoglycoside antibiotic used in ophthalmic and intravenous treatments to treat bacterial infections by blocking protein synthesis.[1] Determinations of tobramycin, kanamycin and other aminoglycoside antibiotics have been previously demonstrated by HPAE-IPAD since 2004.[2–6] This document updates Thermo Scientific™ Application Note 61 using a highpressure-capable Dionex Integrion HPIC system equipped with updated EG technology and an electrochemical detector.

In the electronics industry, ionic contamination in the range of parts per trillion (ppt, ng/L) to parts per billion (ppb) concentrations is a major concern, causing corrosion-related failures in production and final product. Ionic contamination is increasingly important as the devices decrease to size. This technical note demonstrates automated calibration and water purification on an ICS-5000+ HPIC dual IC system to minimize the system and environmental contamination which resulted in increased sensitivity to double-digit-ppt concentrations. An ICS-6000 can be used for this application.
