As specified in U.S. EPA Method 314.1, determine trace perchlorate in drinking water and high-ionic-strength water using the Thermo Scientific™ Dionex™ IonPac™ Cryptand C1 Concentrator Column. This adjustable-capacity column contains a macroporous, 17.5μm resin grafted with the macrocyclic 2,2,2 cryptand compound. The column's functional capacity depends on eluent concentration and the type of cation bound within the cryptand molecule. The adjustable capacity makes the Dionex IonPac Cryptand C1 column a powerful tool for determining trace perchlorate in drinking water and high-ionic-strength water. It can be used with a pressurized bottle, syringes, Dionex Autosamplers and a single-piston sample delivery pump for sample loading.

The column is optimized for selective at an operating temperature of 30˚C, and it is ideal for use with large-loop injections.
For high-resolution mapping and analysis of oligosaccharides released from glycoproteins, use the Thermo Scientific™ Dionex™ CarboPac™ PA200 Analytical & Guard Columns to provide sensitive and specific detection. Combined with pulsed amperometric detection (PAD), this anion-exchange column provide fast, reproducible separations with no need for derivatization. The hydrophobic, polymeric, pellicular anion-exchange resin packing material is stable over the range of pH 0–14. This unique pH-stability allows the use of eluent compositions that are conducive to anodic oxidation of carbohydrates at gold electrodes.
Obtain robust, reliable results and fast isocratic separation of common inorganic cations and alkanolamines using the Thermo Scientific™ Dionex™ IonPac™ CS12 Cation-Exchange Column. This is a high-capacity, cation-exchange column designed for the fast, isocratic separation of lithium, sodium, ammonium, potassium, magnesium, and calcium using methanesulfonic or sulfuric acid eluents in diverse sample matrices. However, the newer Thermo Scientific™ Dionex™ IonPac™ CS12A column provides improved performance and is the recommended column for inorganic cation analysis.
Analyze trace bromate and other oxyhalides in drinking water, ground water, wastewater, and other diverse matrices using the Thermo Scientific™ Dionex™ IonPac™ AS23-4µm columns. The high capacity and selectivity of this column facilitates the determination of trace bromate at low-µg/L levels in the presence of high amounts of chloride, sulfate, and carbonate. Compared to Dionex IonPac AS23 column, the new Dionex IonPac AS23-4µm columns use smaller resin particles for more efficient separations resulting in more accurate peak integration and more reliable results.
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.
Separate multivalent and polarizable anions in 25 minutes without solvents using the Thermo Scientific™ Dionex™ IonPac™ AS25 column. This high-capacity, hydroxide-selective, anion-exchange column is ideal for the determination of sulfur species in complex matrices such as food and beverage samples as well as wastewater effluents from the industrial, chemical, and petrochemical industries. This column delivers fast, simple separation of polarizable anions, including thiosulfate, iodide, thiocyanate, and perchlorate. For the best peak shape of polarizable anions, use the Thermo Scientific™ Dionex™ IonPac™ AS16 column or the Thermo Scientific™ Dionex™ IonPac AS20 column.
For isocratic separations of mono- and disaccharides in foods, drugs, and plants, the Thermo Scientific™ Dionex™ CarboPac™ PA10 Capillary, Analytical & Guard Column provides superior selectivity. Combined with pulsed amperometric detection (PAD), this anion-exchange column delivers high-resolution separations. It is an ideal choice for separating mono- and disaccharides in mammalian glycoproteins. The column efficiently resolves fucose from the system void and from protein hydrolysate interferents. Oxygen elutes after mannose, eliminating interference with monosaccharides.
Deliver excellent results for fast isocratic separations of inorganic anions in diverse matrices with the Thermo Scientific™ Dionex™ IonPac™ AS14 Carbon Eluent Anion-Exchange Column. This universal column for the separation of inorganic anions delivers improved peak resolution and retention of fluoride in applications performed previously with the Dionex IonPac AS4A, AS4A-SC and AS12A columns, however, the Dionex IonPac AS22 Carbonate Eluent Anion-Exchange column, an advanced carbonate eluent column, is recommended for fast analysis of inorganic anions.
