Dionex AC-ER 淋洗液再生系統(tǒng)陰離子集中柱

對AC-ER陰離子濃縮柱是一個(gè)通用的，低死體積，用類似的特征的UTAC 2聚光極低壓陰離子濃縮柱，但具有減少死體積和容量。對AC-ER被容納在一個(gè)4×16 mm色譜柱體為非常低死體積大化，可以在一個(gè)進(jìn)行注射的次數(shù)
洗脫液交易所之間的RFIC-ER系統(tǒng)。對AC-ER列具有12.0μeq/柱的容量和大約70微升的空隙體積。

憑借安裝在RFIC-ER系統(tǒng)的AC-ER列，每次注射只增加了75微升樣品基質(zhì)進(jìn)入洗脫液，無論樣本量（70μL+ 5μL連接管）的。因此266注射可以需要之前洗脫液進(jìn)行替換，無論裝載到集中器樣品的實(shí)際量來進(jìn)行。并通過使用代替AC-ER的矩陣消除步驟，溶劑可以直接注射到AC-ER然后注射到RFIC-ER系統(tǒng)之前沖洗掉。對AC-ER集中器能夠?qū)FIC-ER系統(tǒng)，包括溴酸鹽的分析至5ppb飲用水，并在乙醇中常見陰離子的分析應(yīng)用程序的主機(jī)。

交流-ER陰離子濃縮柱的特點(diǎn)：

極低的背壓
極低死體積
與AS，AS-HV和AS-DV自動進(jìn)樣器兼容

Dionex AC-ER 淋洗液再生系統(tǒng)陰離子集中器

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
