Obtain consistent reliable results for the analysis of aliphatic amines, aromatic amines, and polyamines using methanesulfonic acid (MSA) or sulfuric acid eluents with the Thermo Scientific™ Dionex™ IonPac™ CS14 Cation-Exchange Column. The column facilitates resolution of a large number of aliphatic amines and Group I and Group II cations in diverse sample matrices. However, the newer Thermo Scientific™ Dionex™ IonPac™ CS17, CS19 and CS19-4µm cation-exchange columns are recommended for these separations.
Separate common cations in as little as four minutes using methanesulfonic acid (MSA) or sulfuric acid eluents with Thermo Scientific™ Dionex™ IonPac™ CS12A Cation-Exchange Columns. These medium-capacity, carboxylate-functionalized cation-exchange columns are recommended for fast, isocratic separation of lithium, sodium, ammonium, potassium, magnesium, and calcium in diverse sample matrices. The IonPac CS12A column is the recommended replacement for all IonPac CS12 column applications.
Analyze inorganic cations and amines using the Thermo Scientific™ Dionex™ IonPac™ CS20 ion chromatography (IC) columns. Designed to complement Dionex IonPac CS18 and Dionex IonPac CS19 columns, the Dionex IonPac CS20 columns provide a large separation window between monovalent and divalent cations. This allows most amines to elute after the alkali metals but before the alkaline earth metals, moving the amines away from matrix ions that would normally make quantitation difficult. Its selectivity makes the Dionex IonPac CS20 particularly useful for determining a variety of alkyl and alkanol amines.
Analyze trace bromate in drinking water with the Thermo Scientific™ Dionex™ IonPac™ AS9-HC medium-capacity, carbonate eluent, anion-exchange column. Specifically designed for trace bromate in drinking water, the Dionex IonPac AS9-HC column is the specified column for U.S. EPA Methods 300.1 and 317.0. However, the advanced, high-capacity Dionex IonPac AS23 Carbonate Eluent Anion-Exchange column is recommended for determination of oxyhalides and inorganic anions, such as trace bromate, in ozonated drinking water.
Resolve a large number of inorganic anions and organic acid anions in complex matrices with the Thermo Scientific™ Dionex™ IonPac™ AS11-HC Capillary, Analytical & Guard Column. Complex sample matrices such as chemical wastewater effluents and fermentation broth solutions contain a variety of inorganic anions and organic acids. With the high-capacity Dionex IonPac AS11-HC column, you can inject higher concentration samples without column overloading or peak broadening.
The Dionex IonPac AS11-HC column was specifically designed to resolve analytes in a single run using a hydroxide gradient. The high-capacity column delivers improved separation for monovalent carboxylic acids including: quinate, lactate, acetate, propionate, formate, and butyrate.
For fast analysis of aliphatic organic acids and alcohols in complex or high-ionic strength samples, the Thermo Scientific™ Dionex™ IonPac™ ICE-AS6 Analytical & Guard Column delivers consistent, reliable results. The column uses a moderately hydrophilic resin functionalized with sulfonic acid groups and carboxylic acid groups for increased selectivity in the determination of aliphatic organic acids and alcohols in samples that include food and beverage products, biological samples, industrial process liquors, and wastewater.
Attain the optimal combination of chromatographic speed and resolution using the Thermo Scientific™ Dionex™ IonPac™ AS22-Fast-4µm column. Designed specifically for compliance monitoring of inorganic anions in accordance with U.S. EPA Method 300.0 (A), this moderate capacity column combines the selectivity of the Dionex IonPac AS22-Fast column with fast high resolution separations. Compared to the Dionex IonPac AS22-Fast column, the new Dionex IonPac AS22-Fast-4µm column uses smaller resin particles for more efficient separations resulting in faster run times, more accurate peak integration and more reliable results.
Simplify trace analysis of perchlorate in drinking water, surface water, and groundwater matrices using the Thermo Scientific™ Dionex™ IonPac™ AS20 Capillary, Analytical & Guard Columns. The capacity and selectivity of this column ensures that perchlorate can be quantified at low µg/L concentrations using suppressed conductivity detection, even in the presence of very high concentrations of chloride, carbonate, and sulfate. This column is specified in U.S. EPA Method 314.1 for the determination of trace perchlorate in drinking water (Confirmatory Method) after sample preconcentration.
Obtain consistent, reliable results for the determination of disparate concentration ratios of ethanolamine and ammonium in diverse sample matrices using the Thermo Scientific™ Dionex™ IonPac™ CS15 Cation-Exchange Column. This is a medium-capacity carboxylate-functionalized cation-exchange column with crown ether moiety. The column has unique selectivity, and is the only carboxylic acid based cation column from Dionex in which ethanolamines elute before ammonium. Thus, it is the column of choice for samples with high ammonium to low ethanolamine ratios.
Determine trace-level concentrations of inorganic anions and low-molecular-weight organic acids in high-purity water matrices with the Thermo Scientific™ Dionex™ IonPac™ AS15 Capillary, Analytical & Guard Columns. Specifically designed for analysis of trace anions in high-purity water matrices used by the semiconductor and power generation industries, the column delivers high sensitivity and superior resolution of early-eluting anions (e.g., fluoride, glycolate, acetate, and formate). The column is optimized for selective at an operating temperature of 30˚C, and it is ideal for use with large-loop injections.
Designed specifically for compliance monitoring of inorganic anions in accordance with U.S. EPA Methods 300.0 (A), the Thermo Scientific™ Dionex™ IonPac™ AS22 Analytical, Capillary & Guard Columns provide fast analysis of drinking water, ground water and wastewater. With the Dionex IonPac AS22 column, using a simple isocratic carbonate/bicarbonate eluent, common inorganic anions can be quickly separated in a variety of sample matrices including drinking water, wastewater, process streams, and scrubber solutions.
