Dionex AC-ER 淋洗液再生系统阴离子集中柱

对AC-ER阴离子浓缩柱是一个通用的，低死体积，用类似的特征的UTAC 2聚光极低压阴离子浓缩柱，但具有减少死体积和容量。对AC-ER被容纳在一个4×16 mm色谱柱体为非常低死体积大化，可以在一个进行注射的次数
洗脱液交易所之间的RFIC-ER系统。对AC-ER列具有12.0μeq/柱的容量和大约70微升的空隙体积。

凭借安装在RFIC-ER系统的AC-ER列，每次注射只增加了75微升样品基质进入洗脱液，无论样本量（70μL+ 5μL连接管）的。因此266注射可以需要之前洗脱液进行替换，无论装载到集中器样品的实际量来进行。并通过使用代替AC-ER的矩阵消除步骤，溶剂可以直接注射到AC-ER然后注射到RFIC-ER系统之前冲洗掉。对AC-ER集中器能够对RFIC-ER系统，包括溴酸盐的分析至5ppb饮用水，并在乙醇中常见阴离子的分析应用程序的主机。

交流-ER阴离子浓缩柱的特点：

极低的背压
极低死体积
与AS，AS-HV和AS-DV自动进样器兼容

Dionex AC-ER 淋洗液再生系统阴离子集中器

The AC-ER Anion Concentrator Column is a general-purpose, low dead volume, extremely low pressure anion concentrator column with similar features to the UTAC 2 concentrators, but with reduced dead volume and capacity. The AC-ER is housed in a 4 x 16 mm column body for very low dead volume to maximize the number of injections that can be made on an
RFIC-ER system between eluent exchanges. The AC-ER column has a capacity of 12.0 μeq/column and a void volume of approximately 70 μL.

With an AC-ER column installed in an RFIC-ER system, each injection only adds 75 μL of sample matrix into the eluent regardless of the sample volume (70 μL + 5 μL for connecting tubing). Thus 266 injections can be performed before the eluent needs to be replaced, regardless of the actual amount of sample loaded onto the concentrator. And by using a matrix elimination step with the AC-ER in place, solvents can be directly injected onto the AC-ER then flushed off before injection into the RFIC-ER system. The AC-ER concentrator enables a host of applications on RFIC-ER systems, including analysis of bromate to 5 ppb in drinking water, and analysis of common anions in ethanol.

The AC-ER Anion Concentrator Column features:

• Extremely low backpressure

• Very low dead volume

• Compatible with AS, AS-HV and AS-DV Autosamplers

• Ultraclean (low sulfate)

• Supports carbonate/bicarbonate eluents
