The ICW-3000™ system is an ideal solution for feeding ultrapure water directly to Dionex® Ion Chromatography (IC) eluent generators and suppressor regenerating lines. Just fill the 10-liter tank with pure water to produce ultrapure water that is directly supplied to the ion chromatography system.
The Dionex® ICS systems include an eluent generator (EG), which is a device that can produce a defined concentration of eluent from ultrapure water and a concentrated eluent cartridge (potassium hydroxide, potassium carbonate, methanesulfonic acid).The ICW-3000™ system allows greater IC analytical precision, while also making operation more convenient when Dionex® ICS systems are used in external generation mode. The ICW-3000™ system can supply ultrapure water to the suppressor at adequate pressure and flow rates with no need for gas.
IC Benefits
- Improves reproducibility
- Allows more stable baselines
- Provides better equilibration of the IC system
- Reduces instrument downtime needed to refill eluent bottles
- Reduces IC eluent preparation to almost zero
- Eliminates the need for helium to pressure feed the suppressor
- Extends IC system lifetime
- IC remote control can be used to drive the ICW-3000™ system
- Micro valve included for suppressor line flow regulation

Water Specifications
ICW-3000™ ultrapure water (Type 1)
| Product water resistivity at 25° C * | 18.2 MΩ•cm |
| Product water TOC** | ≤ 5ppb |
| * Product water quality specifications are achievable only if feed water quality is within specifications and for typical operating conditions (i.e. after at least 1 day of regular operation). ** TOC values given for Eluent and Suppressor lines after complete hydration and rinsing of the purification cartridge. |
|
Product water quantity
| Eluent flow | > 4 mL/min |
| Eluent pressure | > 0.2 bar (3 PSI) |
| Suppressor flow | > 20 mL/min |
| Suppressor pressure | > 1.7 bar (25 PSI) |
| Point-of-use flow | > 250 mL/min |
Feed water
| Water quality* | Type II water as defined by ASTM |
| TOC** | < 30 ppb |
| Temperature*** | 5 - 35°C |
| Connection | Removable Tank |
| * Feed water conductivity above specification may prevent to reach the expected water product resistivity or lead to a premature exhaustion of the packs ion-exchange resins. ** Feed water TOC above specification may cause excessive fouling of the ion-exchange resin beads in the cartridge with as possible consequence a decrease of the ion-exchange capacity of the resin. *** A feed water temperature outside specifications may lead to premature damage to the system. |
