Abstract

The invention relates to a sampler (102), in particular for automatic elemental analysers, of the so-called 'drawer' type, comprising loading means (121), a guide (128), a joining block (131) for joining said loading means (121) and said guide (128), an admission piston (126), a purge chamber (134) for a sample (103) to be analysed, a system for injecting (133) a purge gas into said purge chamber (134), which in its turn comprises: an inner passage (136) of said admission piston (126), said admission piston (126) being movable between a drop position (124) and an feeding position (127) for the sample (103) to be analysed; a passage (132)of said joining block (131); a passage (123) of said loading means (121) aligned with the drop position (124) for the sample (103) to be analysed. According to the present invention, means to direct the flow (40) in said purge chamber (134) is comprised within the purge chamber, in order to avoid the phenomenon of retro-diffusion of the ambient atmospheric gases in said purge chamber (134).
