The Dionex IonPac AS16 column simplifies the determination of polarizable anions, including thiosulfate, iodide, thiocyanate, and perchlorate using an isocratic hydroxide eluent.Separate hydrophobic anions (iodide, thiocyanate, and thiosulfate) in less than 20 minCan be used for trace perchlorate in drinking water matricesIdeal for polyvalent anions, including polyphosphates and polycarboxylatesUltralow hydrophobicity allows fast analysis of polarizable anionsThe Dionex IonPac AS16 is a high-capacity, hydroxide-selective column for the determination of polarizable anions in a variety of sample matrices. Trace concentrations of perchlorate in drinking water, surface water, and ground water matrices can easily be determined using a large-loop injection. The Dionex IonPac AS16 column is available in three formats: standard bore (4 × 250 mm), microbore (2 × 250 mm) and capillary (0.4 × 250 mm). The capillary format is packed with the same material as the equivalent standard bore and microbore versions (providing the same performance as a 4 mm and 2 mm column) but requires only 1/100th the eluent flow rate. The capillary format provides the advantage of significantly reduced eluent consumption, which helps reduce operating costs. The Dionex IonPac AS16 capillary column is used in the second dimension of the 2D-IC method for the analysis of trace perchlorate (sub ppb) in drinking water.Note: Also see the Dionex IonPac AS20, with complementary selectivity for confirmation of perchlorate identification when using EPA Method 314.1Dionex IonPac AS16 Anion-Exchange Column SpecificationsDimensionsDionex IonPac AS16 Analytical Column:2 × 250 mm and 4 × 250 mmDionex IonPac AG16 Guard Column:2 × 50 mm and 4 × 50 mmDionex IonPac AS16 Capillary Column:0.4 × 250 mmDionex IonPac AG16 Capillary Guard Column:0.4 × 50 mmMaximum operating pressure4000 psiMobile phase compatibilitypH 0–14 0–100% HPLC solventsSubstrate characteristicsBead Diameter: 9 μmPore Size: 2000 ? super macroporous resinCross-Linking (%DVB): 55%Latex characteristicsFunctional Group: Alkanol quaternary ammonium ionLatex Cross-Linking: 1%Latex Diameter: 80 nmHydrophobicity: UltralowCapacity42.5 μeq (2 × 250 mm analytical column)0.875 μeq* (2 × 50 mm guard column)170 μeq (4 × 250 mm analytical column)3.5 μeq* (4 × 50 mm guard column)1.7 μeq (0.4 × 250 mm capillary column)0.035 μeq (0.4 × 50 mm capillary guard column)*Guards are packed with a low capacity microporous resinColumn constructionPEEK™ with 10-32 threaded ferrule style end fittings.All components are nonmetallic.订购信息:Analytical ColumnsIonPac AS16 Analytical Column (4 x 250 mm)055376IonPac AS16 Analytical Column (2 x 250 mm)055378Dionex IonPac AS16 Capillary Column (0.4 x 250 mm)082315Guard ColumnsIonPac AG16 Guard Column (4 x 50 mm)055377IonPac AG16 Guard Column (2 x 50 mm)055379Dionex IonPac AG16 Capillary Guard Column (0.4 × 50 mm)082316应用谱图:
