What is a graphite furnace atomiser?
Answer: B
A small graphite tube is heated electrically in stages, drying, ashing and then atomising a few microlitres of sample placed directly inside it. There is no flame and no plasma, and nothing is nebulised. Holding the entire sample in the light path for a second or more, rather than sweeping most of it away as a flame does, is what gives the technique its far greater sensitivity.
