Water purification System, EMD Millipore Direct 8 produces Type 1 (Ultra-pure) Water:

Direct 8

Feed Water Nature: Potable Tap Water

Flow Rate: 8 Liters per hour

Product Water Resistivity: Ultrapure Water: 18.2 MegOhm-cm

Product Water TOC: < 5 ppb

​

All systems in the Milli-Q range employ a 3-step purification process.

  • Step 1:  Plug-in Q-Gard purification packs are tailored to the feed water source to optimize the performance of downstream purification media to ensure consistent results.
  • Step 2:  Quantum application-specific cartridges remove ionic and organic contaminants down to trace levels.
  • Step 3:  Final purification of ultrapure water is carried out at the point-of-use by a pharmaceutical-grade, absolute 0.22 µm Millipak membrane filter.

 

Additional Purification Steps

UV Photo-oxidation:

The ultraviolet photo-oxidation process (UV at 254 and 185 nm) used in Milli -Q Gradient, Advantage  Systems can effectively carry out the destruction of organic molecules, to reduce TOC levels to < 5 ppb, improving consistency and sensitivity in applications such as HPLC, IC, solid-phase extraction and UV spectroscopy.
