Installing Solvent-Resistant Components in the Burner

Warning: Flammable Gases – Fire and Explosion Hazard
Not all gaskets in the burner unit are suitable for use with organic solvents.
Exposure to such solvents may cause the respective gaskets to swell. This may
WARNING
result in a seepage of gas which is a serious fire hazard.
Before you aspirate organic solutions, remove the respective gaskets and install
solvent-resistant gaskets.
The standard o-ring in the burner end cap is not resistant to organic solvents. If you intend to aspirate
solutions containing organic solvents you must exchange this o-ring for a solvent-resistant o-ring in the
following way:
1. Where applicable, extinguish the flame, allow the burner head to cool, shut down the gases at source,
and bleed the gas supply lines.
2. Open the atomizer compartment door.
3. Remove the burner head.
4. If corrosive or toxic samples were run previously, pour a large quantity of deionized water slowly
through the neck of the burner chamber to thoroughly flush the inside and the drain system.
5. Remove the nebulizer from the burner end.
6. Remove the burner system from the spectrometer.
7. Take the burner chamber apart.
8. Remove the standard o-ring from the end cap and carefully fit the solvent resistant o-ring.
9. Reassemble the burner system
