Abstract
Electrical contact members 20, 22 for supplying transverse electrical current to a tubular furnace member (22) for electrothermal atomization of samples for analysis by atomic absorption spectrophotometry, the tubular furnace member having diametrically opposite, longitudinally-extending contact ribs (84, 86). The contact members (20, 22) form, in operative assembly, a cavity 88 in which tubular furnace member (24) is accommodated and is held between V-shaped channels (44, 76) in contact members (20, 22). Cavity 88 is formed by a recess (36) in one contact member (20) and covered, except for a separating gap, by the other contact member (22). Respective inert protective gas passages (62, 82) terminate at one end in channels 44, 76.
