Graphite cuvette for Kvant spectrometers
Cuvette graphite Heating and atomization occur in the graphite cell analyzed sample. A liquid drop of sample, from 5 to 30 microliters, is added using an automatic or manual dispenser. Maximum temperature heating can reach 3000°C. Typically to increase durability and obstruction 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 flow of inert gas, argon or high purity nitrogen. A graphite cuvette, or in other words, a graphite furnace, sometimes called tubular because of its forms.
