Nebulizers, Spray Chambers and Torches

Torches

The two basic torch designs are the Greenfield and Fassel torches. The Greenfield torch requires higher gas flows and RF powers. The Greenfield torch is more rugged (less likely to extinguish due to misalignment and introduction of air) whereas the Fassel torch requires less Ar and power. Both designs produce similar detection limits.

Some nebulizer designs work better with one torch design over another. Before experimenting with torches, it is best to contact your instrument manufacturer to determine the torch design recommended for your instrument as well as any design specifications, operating conditions, and dimensions that must be observed.
