Abstract
A sample preprocessing system for a fluorescent X-ray analysis includes a sample preprocessing apparatus for retaining on a surface of a substrate a substance to be measured that is found on the surface of the substrate, after such substance has been dissolved and subsequently dried, a transport apparatus for transporting the substrate, and a control apparatus for controlling the sample preprocessing apparatus and the transport apparatus. The control apparatus after having confirmed that the pressure difference between inside and outside of the apparatus ( ) and the concentration of the reactive gas within the apparatus are within a predetermined range causes automatically opening and closing shutters and to thereby avoid a possible corrosion of the apparatuses positioned outside the sample preprocessing apparatus while increasing the service lifetime thereof.
