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4×16 mm色譜柱體為非常低死體積大化,可以在一個進(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

AC-ER Anion Concentrator for RFIC-ER | 072778 |
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
