ABSTRACT:
A cuvette consisting of a basic hollow member of pyrolytic graphite which is treated at least on the outside surface by a local mechanical abrasion is provided for use in atomic absorption spectroscopy. Since the mechanically treated surfaces may form the inner and outer surfaces of the cuvette, it has been found that the cuvette need not be after-coated or sealed with pyrolytic graphite, but may be of a finally finished form following this mechanical abrasion. Accordingly, cuvettes of substantially smaller wall thicknesses, and substantially smaller mass, are formed with the same or even increased rigidity than commercially available graphite cuvettes which may have or not have a pyrolytic graphite coating.
