AN72333: Determination of Adsorbable Organic Halogen in Wastewater using a Combustion Ion Chromatography SystemInstrument Type: IC
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.
AN666: Routine analysis of polar pesticides in water at low ng/L levels by ion chromatography coupled to a triple quadrupole mass spectrometerInstrument Type: ICMS
We present an IC-MS/MS based method for high-throughput screening and quantitation of polar pesticide residues and their metabolites in water matrices below the current legislative requirements. Direct injection eliminates long and laborious sample preparation and makes the method more sensitive and faster than traditionally used LC-MS/MS methods, which utilize FMOC derivatization. This method can increase cost savings, provide more reliable results, and increase sample throughput.
AN72268: Determination of Fluoride in Tea using a Combustion Ion Chromatography SystemInstrument Type: IC
This application note demonstrates a simple combustion ion chromatography (CIC) method to determine fluoride in tea. Using the CIC system including a Mitsubishi Automatic Combustion Unit AQF-2100H system and a Thermo Scientific Dionex Integrion HPIC system, fluoride in tea is determined in 20 min (11 min if the combustion and chromatography functions are overlapped), a significant time savings over the current Chinese national method which requires more than a hour. The CIC method is sensitive (MDL=1 ppm), precise, and accurate. The only sample preparation required is to grind and dry the tea.
AN1161: Improved Method for Determination of Biofuel Sugars by HPAE-PADInstrument Type: IC
The current work updates the system used for the carbohydrate analysis in AN1089. The new system combines flexibility and ease-of-use with high sensitivity and selectivity, bringing a higher level of convenience and cost effectiveness to simple sugar analysis. The method proposed here separates eight common carbohydrate sugars in less than eight minutes. The shorter run time results in better process economics. Using this method, carbohydrates present in 10 individual biofuel samples were quantified.
AN661: Fast routine analysis of polar pesticides in foods by suppressed ion chromatography and mass spectrometryInstrument Type: ICMS
We present a reliable and cost-effective IC-MS/MS multi-residue method for high-throughput screening and quantitation of polar pesticide residues and their metabolites in food matrices below the current legislative requirements. In contrast to methods described in the literature, sample preparation is simplified and the use of ion chromatography speeds up the separation.
