SHOCK AND FIRE HAZARD
The system must be plugged into an outlet which has a protective ground
connection.
Ensure that you position the system so that the location where the power
supply cord plugs into it is easily accessible (is not blocked) and it can be
quickly disconnected if needed. In case of hazard, the system should be
disconnected from the power source.
Do not apply power until ready to operate the system.
ICP-MS Requirements
To achieve optimum performance with the Aridus II
™
, the ICP-MS system must
meet factory specifications from your vendor and be in good operating
condition. Check the ICP-MS performance using the standard sample
introduction system before Aridus II
™
installation. If the sensitivity, oxide ratios
and overall performance do not meet instrument specifications, consult the
ICP-MS Operator’s Manual. If ICP-MS performance specifications are met, then
begin installation of the Aridus II System.
In order for the C-Flow PFA nebulizer to properly self-aspirate, a minimum
argon gas pressure of 420 kPa (60 psi, 4.2 bar) is required in the nebulizer gas
line. Ensure that the Ar gas supply for the C-Flow PFA nebulizer is from a
known, good supply. The argon nebulizer gas supply from the host ICP-MS is
typically used for the C-Flow nebulizer.
Gas Requirements
The argon gas supply for the Aridus II
™
sweep gas may be teed in from the
main ICP-MS instrument argon gas supply. Nitrogen gas must be supplied from
an external source at a pressure of at least 350 kPa (50 psi, 3.5 bar). Nitrogen
with a minimum purity of 99.995% should be used.
