產(chǎn)品特點:

The CRD 200 用氫氧根體系淋洗液能除去樣品中二氧化碳，這能除去氫氧化鈉淋洗液中常見的碳酸根色譜柱。
The CRD 300 能除去碳酸根體系淋洗液中的碳酸，這樣用碳酸鹽體系淋洗液，能達到用氫氧根體系淋洗液相同的洗脫效果。

Reduces Carbonate for Improved Sensitivity

產(chǎn)品應用:

The Carbonate Removal Device （CRD 200） removes carbon dioxide from the suppressed eluent stream by diffusion through the walls of a gas permeable membrane. With carbonate eluent systems it reduces the background signal to nearly the same levels as that of hydroxide eluents. Plumbed after the suppressor, the carbon dioxide transfer is aided by a countercurrent flow of basic solution.

The CRD 200 is optimized for the removal of carbonate from hydroxide eluent systems

Minimizing carbonate using the CRD 200 can improve quantification

The increased membrane length of the CRD 300 is optimized for carbonate eluent systems

Reducing the baseline with a CRD 300 results in higher sensitivity

Elimination of the carbonic acid matrix with a CRD 300 increases the linearity range

Exposure to carbon dioxide can cause samples to become contaminated with carbonate. High levels of carbonate originating from dissolved carbon dioxide can interfere with the accurate determination of analytes of interest, such as sulfate and nitrite.

The CRD 200 can be installed easily in any Dionex IC system equipped with an eluent generator, CR-ATC, and ASRS® 300 or ACES® 300 suppressor. The CRD 200 requires no reagents or software control. The CRD 200 is a low-dispersion device designed specifically for use with hydroxide- and borate-based chemistries using Dionex columns.

The CRD 200 is available in three formats. The CRD 200 （4 mm） supports carbonate removal from standard bore systems, the CRD 200 （2 mm） supports carbonate removal from microbore systems, and the CRD 200 （Capillary） supports carbonate removal from capillary-scale systems at flow rates of 5 – 30 μL/min

A significant amount of carbonate is removed using the CRD .

Background signal is reduced using the CRD 300.

The CRD 300 is easily installed in any Dionex IC system equipped with an ASRS 300 suppressor. It requires either a constant flow of basic solution from a peristaltic pump or evacuation by a vacuum pump. It is a low-dispersion device designed for use with carbonate-based chemistries using Dionex columns.

The CRD 300 is available in two formats. The CRD 300 （4 mm） supports carbonate removal from standard bore systems, while the CRD 300 （2 mm） supports carbonate removal from microbore systems.
