【详细说明】
Dionex IonPac AS18-4?m Hydroxide-Selective Anion-Exchange ColumnFast, High-Resolution Determination of Inorganic Anions and Low-Molecular-Weight Organic AcidsAttain the optimal combination of chromatographic speed and resolution using the new Thermo Scientific Dionex IonPac AS18-4?m anion-exchange column. This high-capacity, high-efficiency column provides excellent resolution of inorganic anions in diverse sample matrices. Compared to the previous Dionex IonPac AS18-Fast column, the new ion-exchange column uses smaller resin particles for more efficient separations resulting in faster run times, more accurate peak integration and more reliable results.The Dionex IonPac AS18-4?m anion-exchange column is the hydroxide-selective column of choice for compliance monitoring of inorganic anions in drinking water and wastewater samples in accordance with US EPA Methods 300.0 (A) and 300.1.&The new&Dionex IonPac AS18-4?m column offers the same selectivity as the Dionex IonPac AS18-Fast column, but with the reduced particle size, this column can separate the common inorganic anions in significantly less time without loss of resolution. Applications run on the Dionex IonPac AS18-Fast column can be easily transferred to the Dionex IonPac AS18-4?m column with the benefit of reduced run time with no loss in resolution. The Dionex IonPac AS18-4?m column is available in capillary format (0.4 × 150 mm), microbore format (2 × 150 mm) and standard bore format (4 × 150 mm). The capillary format offers the advantage of reduced eluent consumption, thereby lowering operating costs. &Decrease run times, increase sample throughput without loss of resolutionSuper fast isocratic separation of the common inorganic anions (less than 3 min)&Recommended hydroxide-selective column for inorganic anions in diverse sample matricesInorganic anion and low-molecular weight organic acids in complex sample matricesMeets performance requirements specified in US EPA Method 300.0 (A)The smaller resin particles used in the Dionex IonPac AS18-4?m column produce increased back pressure. When operating the Dionex IonPac AS18-4?m capillary column at the standard flow rate of 0.010 mL/min, an IC system capable of operating up to 3000 psi is sufficient. However, to take advantage of the fast runs, using elevated flow rates, a high pressure capillary IC system, such as the Thermo Scientific Dionex ICS-5000+&HPIC or the Thermo Scientific Dionex ICS-4000 HPIC is required. The Dionex ICS-5000+&HPIC systems is required for standard operation of the Dionex IonPac AS18-4?m&microbore and standard bore columns.Dionex IonPac AS18-4?m Anion-Exchange Column SpecificationsDimensionsDionex IonPac AS18-4?m Capillary Column:0.4 × 150 mmDionex IonPac AG18-4?m Capillary Guard Column:0.4 × 35 mmDionex IonPac AS18-4?m Analytical Columns:4 × 150 mm, 2 × 150 mmDionex IonPac AG18-4?m Guard Columns:4 × 30 mm, 2 × 30 mmMaximum Operating Pressure5000 psi (34 MPa)Mobile Phase CompatibilitypH 0C14; 0C100% HPLC solventsLatex CharacteristicsFunctional Group: Alkanol quaternary ammonium ionLatex Crosslinking: The effective crossslinking after functionalization is 8%Latex Diameter: 65 nmHydrophobicity: LowSubstrate CharacteristicsBead Diameter: 4 ?m supermacroporous resinPore Size: 1500 ?Crosslinking (%DVB): 55%Capacity1.71 ?eq (0.4 × 150 mm capillary column)0.07 ?eq* (0.4 × 35 mm capillary guard column)171 ?eq (4 × 150 mm analytical column)6 ?eq* (4 × 30 mm guard column)45 ?eq (2 × 150 mm analytical column)1.5 ?eq* (2 × 30 mm guard column)*Guards are packed with a low-capacity microporous resin.Column ConstructionPEEK with 10-32 threaded ferrule-style end fittings.All components are nonmetallic.Analytical ColumnsDionex IonPac AS18-4?m Capillary Column (0.4 x 150 mm)082314Dionex IonPac AS18-4?m Analytical Column (4 x 150 mm)076034Dionex IonPac AS18-4?m Analytical Column (2 x 150 mm)076036Guard ColumnsDionex IonPac AG18-4?m Capillary Guard Column (0.4 x 35 mm)076033Dionex IonPac AG18-4?m Guard Column (4 x 30 mm)076035Dionex IonPac AG18-4?m Guard Column (2 x 30 mm)076037产品留言
