Graphite AAS tubes
Components are made of dense high-purity graphite coated with a well-aligned pyrolytic carbon (Pyro-C) layer:
MPG-6 – fine-grained graphite characterized by high erosion resistance and strength.
R4550 – fine-grained uniform isostatic graphite for complex-shaped parts with high surface quality.
Graphite AAS tubes with Pyro-C coating feature:
- High stability and gas impermeability
- Low detection limit
- Broad range of detectable elements
- Long life when analyzing aggressive samples
- Longer service life as compared to uncoated tubes.
Graphite components are used in Atomic Absorption Spectrometry devices, e.g.:
