general, provide sufficient protection, but additional side shields will ensure a
further margin of safety. Safety glasses will also provide mechanical protection
for the eyes.
ICP-OES instruments generate high amounts of radio-frequency energy in
their RF power supply and torch boxes, which is potentially hazardous, if
allowed to escape. Safety devices and screening interlocks should not be
bypassed or disconnected.
The power supply of an ICP-OES is capable of generating potentially lethal
voltages. No maintenance beyond what's described in the User Hardware
Guide and Service Manual should be performed by anyone other than a
PerkinElmer Customer Support Engineer or the customer's own PerkinElmer-
trained maintenance personnel.
Water lines should be located away from electrical connections. Condensation
and possible leaks may create an unsafe situation, if in proximity to electrical
connections.
The above suggestions do not supersede the safety standards outlined by OSHA or
other local state and/or country safety organizations governing safe compressed
gas cylinder handling and laboratory safety practices.

Gases for the Avio 500 ICP

Argon is used as the ICP torch gas with the Avio 500. Nitrogen is recommended
for the optical purge gas, although argon can be used as well. The quality criteria
for the argon and the nitrogen are shown in Table 2.
