Abstract
A cuvette for atomic absorption spectrometry includes a tube of pyrolytic graphite, electrographite or vitreous carbon with flanges provided at the ends of the tube, or in the proximity thereof, and having a common envelope of pyrolytic graphite. The flanges consist of solid layers of pyrolytic graphite in which the layer planes of the pyrolytic graphite are either directed perpendicularly to the longitudinal axis of the tube, or extend everywhere parallel to the longitudinal axis and the surface of the tube. Cuvettes with flanges having an orientation of the solid layer planes directed perpendicularly to the longitudinal axis of the tube are considered and operate as 'fast', whereas those having an orientation extending everywhere parallel to the longitudinal axis are considered.
