Description of the system
The Milli-Q IQ 7000 manages the production and the distribution of ultrapure water from a
puried water source. It consists of two main units:
• The water purication unit manages the production of ultrapure water.
• The Q-POD unit (at least 1, up to 4) integrates the screen interface and manages the
dispensing.
Puried water either from a pressurized loop or a storage tank enters the purication unit. It is
rst puried by the IPAK Meta
®
polishing cartridge composed of ion-exchange resins, removing
the bulk of the ions. The puried water then ows to the mercury-free ech

lamp. Organic molecules are partially oxidized, resulting in ions. These can then be captured in
the next stage when the puried water enters the IPAK Quanta
®
polishing cartridge, composed of
ion-exchange resins and synthetic activated carbon. The IPAK Meta and IPAK Quanta cartridges
always need to be replaced together to ensure optimal purication down to traces. Throughout
the purication steps, quality parameters are monitored with resistivity sensors and the A10
®
TOC (total oxidizable carbon) monitor. The A10 TOC Monitor uses a small lamp during its TOC
analysis mode. This is called the ech
