Description
Description: 4 mm CRD 300 w/ VP Vacuum Pump Kit
Unit Size: Each 1
Plumbed between the suppressor and detector cell, carbonate transfer is aided by a countercurrent flow of basic solution. Dionex CRD 300 Carbonate Removal Device
• Designed for use with carbonate eluent-based chemistries using Thermo Scientific™ Dionex™ IC columns
• Removes carbonic acid from the suppressed carbonate eluent
• Provides a detection system that is similar to systems using hydroxide eluents
• Reduces the baseline for higher sensitivity
• Increases linearity range
• Available in two formats:Dionex CRD 300 (4mm) for standard bore systemsDionex CRD 300 (2mm) for microbore systemsDionex CRD 300 can be installed in any Dionex IC system running carbonate as an eluent with a Dionex AERS 500 suppressor. The device requires either a constant flow of basic solution from a peristaltic pump or evacuation by a vacuum pump. See Dionex CRD Carbonate Removal Device Accessories for peristaltic pump and tubing. The Dionex CRD requires no reagents or software control. Dionex CRD 180 and 200 Carbonate Removal Devices The Dionex CRD 180 and 200 device enhances IC signals by continuously removing carbon dioxide from the sample on any Dionex™ Reagent-Free™ IC (RFIC™) system using hydr[oxide eluent.
• Designed for use with hydroxide- and borate-based chemistries using Thermo Scientific™ Dionex™ IC columns
• Removes the carbonate introduced from samples with high levels of dissolved carbon dioxide
• Improves integration and quantitation of some analyte peaks that elute close to carbonate, such as such as sulfate
• Available in several formats:Dionex CRD 200 (4mm) for standard bore systems, including standard bore columns packed with 4μm resinDionex CRD 200 (2mm) for microbore systems, including microbore columns packed with 4μm resinDionex CRD 200 (Capillary) for capillary-scale systems (0.4mm columns) using flow rates of 5–30μL/minDionex CRD 180 (Capillary) is a version of the Dionex CRD 200 that has reduced internal volume and supports carbonate removal from 0.25mm and 0.4mm capillary columnsThe Dionex CRD 180 and 200 device is easily installed in any Dionex RFIC system equipped with an eluent generator; a Thermo Scientific™ Dionex™ CR-ATC Continuously Regenerated Anion Trap Column; and a Thermo Scientific™ Dionex™ AERS™ 500 Anion Electrolytically Regenerated Suppressor or Dionex™ ACES™ 300 Anion Capillary Electrolytic Suppressor.
