The scraper, an optimized module for cleaning the burner slot, guarantees an interference-free and continuous sequence of measurements when the contrAA® is operated with a nitrous oxide flame.
Injection switch
The injection switch (SFS – Segmented Flow Star) helps to reduce transport and vaporization interferences and to maintain stable burner conditions, particularly when only a small sample volume is available or when samples with high acid or salt content have to be analysed.
Hydride systems
Different hydride systems also offer selective analysis of mercury and the hydride elements, depending on the application.
