n a graphite cuvette, the analyzed sample is heated and atomized. A liquid drop of sample, 5 to 30 microliters, is applied using an automatic or manual dispenser. The maximum heating temperature can reach 3000°C.
As a rule, to increase durability and prevent vapor diffusion through the walls of the cuvette, it is covered with a pyrolytic coating.
To protect against burnout in air, graphite cuvettes are placed in a semi-hermetic volume, purged with a stream of inert gas, argon, or high purity nitrogen.
A graphite cell, or in other words, a graphite furnace, is sometimes called a tubular furnace because of its shape.
Used for atomic absorption spectrometers with electrothermal atomization Kvant.Z , Kvant.Z1 and Kvant Z.ETA
