AN1089: Determination of Carbohydrates in Acid Hydrolysates of Wood - Method 2

Instrument Type: IC

This work develops methods for the determination of carbohydrates in wood acid hydrolysates using a CarboPac SA10-4μm column, along with a 0.4 µL injection and thicker working electrode gasket. This column contains smaller resin particles, enabling high-resolution, high-efficiency separation, particularly for the rhamnose-galactose that has been challenging to resolve with previous methods. The described method is fast, provides good sensitivity and consistent response, and can be routinely used to determine sugars in wood samples. An ICS-6000 can be used for this application.

AN1163: Determination of Anions on the Surface of Printed Circuit Boards by IPC-TM-650 Method 2.3.28 using HPIC

Instrument Type: IC

Ion chromatography (IC) has become an important technique for the evaluation of ionic cleanliness. This application note describes an IC method using a Thermo Scientific™ Dionex™ IonPac™ AS11-HC-4μm column and a Thermo Scientific™ Dionex™ ICS-5000+ HPIC system to determine extractable anionic contaminants on the surface of PCBs, including inorganic anions and weak organic acids (WOAs) following the extraction procedure described in IPC-TM-650 Method 2.3.28. An ICS-6000 can be used for this application.

TN72206: Configuring the Dionex Modular HPIC System with an Inline Water Purifier and Inline Calibration for Trace Anion Determinations in Ultrapure Water: EWP Water Blank

Instrument Type: IC

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.

TN72206: Configuring the Dionex Modular HPIC System with an Inline Water Purifier and Inline Calibration for Trace Anion Determinations in Ultrapure Water: 50 ppt Standard

Instrument Type: IC

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 as a 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.
