ABSTRACT:
In a device for analyzing samples for mercury and/or hydride-forming elements by means of atomic absorption spectroscopy, a first arrangement for determining the mercury according to the amalgam method comprising passage throttling means in the form of a washing bottle and a tube connected downstream to a reaction vessel, the other end of which tube is connected to the measuring cell. The tube contains a gold net adapted to be heated and recooled according to the amalgam method. The second arrangement by which hydrides of the sample are directly connected to the measuring cell employs a conduit which leads directly to the measuring cell, bypassing the gold net by branching off from between the reaction vessel and washing bottle. The tube is connectable to a carrier gas source between the washing bottle and position of the gold net in the tube through a first shut-off valve. A second shut-off valve is arranged in the conduit directly leading to the measuring cell. The first and the second shut-off valves are interconnected so that opening the first shut-off valve causes the second shut-off valve to close.
