Dionex IonPac UTAC-LP2 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。
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 concentrator
Dionex IonPac UTAC-ULP2 (5x23mm) 超低压（<30 psi at 2mL/min) anion concentrator
Dionex 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）

订货信息：
| UTAC-LP2 Ultra Trace Anion Concentrator- Low Pressure (4 x 35 mm) | 079917 |
The IonPac? UTAC-LP2 Ultratrace Anion Concentrator Column is an anion-exchange concentrator column with low void volume (approximately 145 μL). This ultraclean (low sulfate) concentrator column is designed primarily for high-purity water analysis. It strips ions from a measured volume of aqueous sample matrix, concentrating the analyte species and lowering detection limits. Backpressure resilience has been improved to eliminate the need for a pulse damper on the loading pump, and matrix resilience has been improved to allow direct injection of samples containing polyacrylic acid additives.
Low-backpressure
Compatible with the AS-DV Autosampler, and Loading Pumps
Ultraclean (low sulfate)
Supports carbonate/bicarbonate, borate, and hydroxide eluents
