Daily Checks

The following maintenance procedures should be done on a daily basis. Make sure
to inspect and replace any hoses which show signs of wear because their failure
could cause a hazard.

Daily Cleaning

At the end of each working day, it is recommended that you flush out the sample
introduction system for five minutes with the plasma on. After analyzing aqueous
solutions, flush with deionized water or a 2% nitric acid solution, followed by
deionized water. After analyzing organic solutions, flush the system using clean
solvent. Also clean the spectrometer housing using a mild lab detergent.

Argon Supply

Make sure that an adequate supply of argon is available and connected to the
system. Check that the argon tank(s) have sufficient pressure, and that a spare tank
is ready if necessary. Argon can be purchased from local suppliers. The argon for
use with ICP systems should be 99.996% pure.
Argon output pressure: 550-825 kPa (80-120 psig)

Purge Gas Supply

The optical path must be purged with either nitrogen or argon. Nitrogen is the
recommended purge gas due to its lower cost. Make sure that an adequate supply
of purge gas is available and connected to the system. Check that the cylinder has
sufficient pressure, and that a spare cylinder is ready if necessary.
The purge gas should be 99.999% pure and is available from local suppliers.
Nitrogen output pressure: 275-825 kPa (40-120 psig)

Shear Gas Supply

The Avio 500 requires a supply of shear gas. The shear gas used is typically
compressed air; however, nitrogen may also be used. Make sure that an adequate
supply of shear gas is available and connected to the system. Check that the supply
has sufficient pressure, and that a spare cylinder is ready if necessary.
Shear Gas output pressure: 550-825 kPa (80-120 psig)
