Abstract
An electrothermal atomizer comprises a tubular graphite body (1) whose ends are clamped between two pairs of graphite contact members (2,4;3,5) which are arranged to form a containment zone for the tubular body (1). The graphite contact members (2,4;3,5) clamp the ends of the tubular body (1) in a radial direction and are separable from each other by an upwardly pivotting movement of the members (2,3). The lower contact members (4,5) are urged towards each other in the direction of the longitudinal axis of the tubular body (1) by means of a leaf spring (42) so that when the clamping force on the tubular body (1) is released by raising the upper contact members (2,3) the tubular body (1) is lightly retained by the lower contact members (4,5). Thus easy access for adjusting the orientation of the tubular body (1) can be obtained, for example to adjust the orientation of the dosing aperture and/or probe entry slot (8).
