Abstract

An electrothermal atomizer comprises a cuvette (1) clamped between two electrodes (2,3) to which an electrical power supply (4) is connected. A probe comprising a tubular head portion (5) and a stem portion (6) is insertable in and removable from the cuvette (1) by means of a rack (9) driven by a motor via a gear (10). By making the probe head (5) in the form of a tube, a large sample volume can be accommodated, and by forming the stem (6) at the top of the tube (5), spreading of acid samples along the stem during the drying phase is minimized.
