General description

Production of volatile organic compound-free ultrapure water at the point of dispense of the Direct-Q® / Simplicity® / Synergy® / Milli-Q® Direct and Reference systems
VOC-Pak® Polisher is designed to purify ultrapure water in the final purification step at point-of-dispense of Type 1 water purification systems. It is an activated carbon-based cartridge specifically designed for the effective removal of volatile organic compounds (VOCs) from ultrapure water.

VOCs are environmental contaminants causing health and safety issues that needs to be routinely analyzed in water, soil, gas and air samples. Specifications for VOCs in drinking water have been established by different regulatory agencies in many countries.
VOC-Pak® Polisher is, therefore, an excellent choice for scientists in need of VOC-free ultrapure water for their analytical applications.

Application

The VOC-Pak Polisher is used to produce VOC-free water for the analysis of VOCs in water by GC and GC-MS when fed by an ultrapure water system.

VOC-free water is suitable for glassware rinsing, blanks, reagents, sample preparation, standard solutions or dilutions in the analysis of those substances, or in studies where VOCs may interfere. It is used in the development of nanoparticle sensors and nanoelectrodes.

Features and Benefits

  • Validated to produce 300 L of VOC-free ultrapure water.
  • Easy maintenance: the polisher is easily installed and replaced.
  • Bottom-tip is redesigned for a secured installation of the protection bell.
  • e-Sure tag for RFID connection with Q-POD® dispenser enables full traceability (data management) and automatic consumable status monitoring on the POD′s touchscreen interface.
  • Certificate of Quality available online.
  • Provides a warranty of water suitable for VOC analysis: blanks and standards preparation; glassware cleaning; and sample dissolution (if VOCs are analyzed in a matrix other than water i.e., in soil).
