Please observe the information provided in the recirculating chiller's operating
instructions.
The system must be filled with cooling water that has been mixed with a cooling water
additive which must be obtained from Analytik Jena. The preparation of the cooling
water is described in section "Changing the cooling water" on page 114. The coolant
additive prevents potential damage to the PlasmaQuant MS resulting from corrosion
and biological contamination. Damage to the device due to operation without coolant
additive is excluded from the warranty!
The PlasmaQuant MS water cooling system incorporates a flow switch to monitor
water flow and an inlet water valve. If a sufficient water flow rate is not maintained,
the plasma will be shut down, inhibiting ignition until sufficient water flow is restored.

Oil-free pump with taper screw technology
The PlasmaQuant MS (Q) is equipped with an adsorption trap (with aluminum oxide).
This trap protects the ICP-MS against oil vapors from the fore-line pump SV40BI.
Aluminum oxide must be replaced once a year by the customer service department.
