IonPac UTAC-ULP2超痕量阴离子浓缩柱
Dionex IonPac UTAC-ULP2超痕量阴离子浓缩柱利用 Thermo Scientific? Dionex? IonPac? UTAC-2 系列超痕量阴离子浓缩柱简化低压、超低压、极低压、痕量高纯水分析。 这些色谱柱为通用型超清洁(低硫酸盐含量)阴离子浓缩柱,特征与 Thermo Scientific? Dionex? IonPac? UTAC-1 系列柱相似,但改善了反压弹性,从而无需在负载泵上安装脉冲阻尼器;基质弹性也得到了改善,从而可以对包含发电行业中使用的聚丙烯酸添加剂在内的样品进行直接进样。描述将水分析的检测限降低 2-5 个数量级Dionex IonPac 阴离子浓缩柱主要为高纯水分析而设计。 浓缩柱可以从已测得体积的水性样品基质中保留阴离子,从而浓缩分析物,并将检测限降低 2-5 个数量级。有三种压力规格可供选择:Dionex IonPac UTAC-LP2 (4x35mm) 低压(60 psi at 2mL/min) anion concentratorDionex IonPac UTAC-ULP2 (5x23mm) 超低压(30 psi at 2mL/min) anion concentratorDionex IonPac UTAC-XLP2 (6x16mm) 极低压(10 psi at 2mL/min) anion concentrator色谱分析性能出色推荐用于氢氧化物、碳酸盐/碳酸氢盐和硼酸盐淋洗液,带或不带溶剂25.0μeq/柱容量低死体积 (~145μL)适用于 4mm 或 2mm 应用兼容 Dionex AS、AS-DV、AS-AP、AS-HV 自动进样器、加压瓶、注射器和单活塞样品传送泵(Dionex AXP 辅助泵)Dionex IonPac UTAC-ULP2超痕量阴离子浓缩柱订货信息:UTAC-ULP2 Ultra Trace Anion Concentrator- Ultra Low Pressure (5 x 23mm)709918The IonPac? UTAC-ULP2 Ultra Trace Anion Concentrator Column is an anion-exchange concentrator column with low void volume of approximately 145 μL. The UTAC-ULP2 is a general purpose concentrator for use with syringe or autosampler loading. This ultralow backpressure concentrator can be used with the AS-DV, AS-HV, or AS Autosamplers, and with single piston sample delivery pumps including the AXP. It is compatible with carbonate/bicarbonate, borate, and hydroxide eluents. Backpressure resilience has been improved to eliminate the need for a pulse dampener on the loading pump, and matrix resilience has been improved to allow direct injection of samples containing polyacrylic acid additives.Ultra-Low backpressure columnCompatible with the AS, AS-HV and AS-DV Autosamplers, and Loading PumpsUltraclean (low sulfate) concentrator columnSupports carbonate/bicarbonate, borate, and hydroxide eluentsIonPac UTAC-ULP2 Ultratrace Anion Concentrator Column 2--Ultra Low Pressure SpecificationsDimensions:5 x 23 mmMobile Phase Compatibility:Hydroxide, carbonate/bicarbonate, or borate eluents 0-100% HPLC solventsSubstrate Characteristics:Bead Diameter: 20 μmCrosslinking (%DVB): 55%Functional Group: Alkanol quaternary ammoniumLatex Characteristics:N/ACapacity:25 μeq/colVoid Volume:145 μLProduct Data SheetsConcentrator and Trap Columns Data SheetReagent-Free Ion Chromatography Systems with Eluent Regeneration Data SheetManualsIonPac UTAC 2 and AC-ER Concentrator Columns Product ManualApplicationsAB 151: Determination of Trace Anions in Nuclear Power Plant Secondary Feed Water Containing Polyacrylic Acid
