Cooling Water Requirements - Agilent Technologies 7700 Series Site Preparation Manual

Cooling Water Requirements

The 7700 ICP- MS requires a controlled supply of cooling water for the RF
generator, turbo molecular pump, load coil, spray chamber and interface. The
water supply is specified by its cooling capacity and its cleanliness.
lists Cooling Water Requirements for the 7700 ICP- MS.
The preferred cooling system is the Agilent Chiller (G3292A) or heat exchanger
(G1879B) filled with Poly- Clear Fluid (G3292- 80010).

* When not using the Chiller or Heat Exchanger in conjunction with Poly-Clear Fluid.
Continued operation with inadequate cooling can cause automatic shutdown of the

7700 ICP-MS and risk potential degradation in the performance of your instrument.
Using tap water can cause contamination to the drinking water line from ICP-MS.
The temperature of water exiting the system should be maintained at less than 40°C.
Water Quality
In the event that the chiller or heat exchanger with Poly- Clear Fluid is not used,
and another type of water re- circulator is used, the reservoir should be filled
with distilled water having a conductance in the range of 50- 150 µs. Distilled
water will keep the system clean. When the Chiller or heat exchanger in
combination with Poly- Clear Fluid is not being used, refer to
water quality standards and recommendations.
