Elemental and Matrix Compatibility

Hydrofluoric Acid Matrices

Hydrofluoric acid (HF) requires the use of HF-resistant introduction systems. These systems are more expensive than glass, have longer washout times, and give a larger measurement precision. However, there are times when the use of HF offers a major advantage over other reagents.

Those elements where an HF matrix may be optimal are shaded in green below:

1. HF is used for Si₃N₄ preparations and other nitrides.
