Low TOC Resins - Semi-Conductor Grade
|
|
 |
Purolite® UltraClean™ UCW9966 and UltraClean™ UCW9964 low Total Organic Carbon (TOC) resins are designed especially for Ultra Pure Water (UPW) production requiring 1 ppb TOC.
For regenerable service deionization (SDI), portable exchange (PE) or cartridge systems, where TOC readings must be less than 10 ppb after rinsing with 30-40 Bed Volumes (BV) or less, UltraClean™ UCW3900, UltraClean™ UCW3700, UltraClean™ UCW3600 resins should be used. Achieving a 10 ppb TOC level after the resins have been installed will depend on the quality of the rinse water.
All UltraClean™ resins undergo treatment to remove the organic residuals that are left on ion exchange resins after manufacturing.
UltraClean™ products are highly regenerated in the H+ and OH- forms.
Product data sheets featuring typical physical and chemical characteristics for each UltraClean™ product are available on this website.
Product Name
UltraClean™ UCW3600 - Ultra pure non-separable mixed bed resin – low attrition
Single component or mixed bed products are readily available. The mixed bed resins are blended using a 60:40 anion to cation ratio by volume, or a 1:1 chemical equivalent ratio. All mixed beds are evaluated using a salt solution until the resin is exhausted. During the exhaustion an in-line resistivity meter records how quickly acceptable water purity is reached, and for how long it is maintained. Every batch of UltraClean™ resin is tested to this standard prior to shipment these resins meet >18.2 MΩ·cm quality.
For further information on obtaining the highest purity water , please see our Technical Bulletin, which provides details of this product range specifically tailored to meet the demanding requirements of Ultra Pure Water (UPW) generation.
