SAMPLE PRESENTATION DEVICE FOR RADIATION-BASED ANALYTICAL EQUIPMENT

摘要

A sample presentation device for radiation-based analytical equipment comprises a mounting base (1), a carrier (3) carried by and adjustable in position relative to the mounting base (1), and an arm (9) extending from the carrier (3) and having at its opposite end a terminal member (10). The carrier (3) and terminal member (10) each have coaxial connectors (11) for receiving two opposite end regions of a capillary tube (7) that forms, in use, a reaction cell. A radiant heater (12) is radially offset from the axis of the coaxial connectors (11) for heating, in use, a capillary tube (7) mounted by way of the coaxial connectors. The carrier (3) and terminal member (10) each have a flow path (15) passing therethrough and communicating with the central bore of the coaxial connectors (11), the flow paths (15) having associated with them heating means (18,19) whereby the flow paths can be heated, in use.
