The said main body consists of a mainframe and a 3D sample sliding stage. Also, the main body is equipped with the illuminant system, the probe and signal processing & MCA modular system. The said 3D sample sliding stage is located at the lower side of the main body for the placement and moving of the samples.

Description

A kind of automatic location X fluorescent energy dispersive spectrometer

Technical field

The utility model relates to a kind of trace element detector device, and especially a kind of testing result accurately and the X fluorescent energy dispersive spectrometer that is user-friendly to and detects.

Background technology

Along with expanding economy, the paces of China's Foreign Trade further strengthen, and the enterprise that belongs to the RoHS of European Union instruction radiation scope is countless, and they are badly in need of wanting a kind of powerful mean, can assist them to tackle the RoHS instruction.The RoHS instruction, full name is " some objectionable impurities instruction is used in restriction in electric, the electronic equipment ", be actually one " Green Trade Barrier " that European Union releases, it is that European Union issued in February, 2003, be intended to limit the decree of using 6 kinds of objectionable impuritiess (lead, mercury, cadmium, 6 valency chromium, poly-bromo biphenyl and poly-dibromodiphenyl ether, these six kinds of objectionable impuritiess in fact only relate to five kinds of harmful elements) in the electronic electric equipment.Its target is consistent with other international regulations, is intended to limit new equipment and uses some objectionable impurities, with protection human health and environment.For the electronics manufacturer beyond the Europe, as long as the equipment final outlet of its production is to EU member country, just must on July 1st, 2006 in accordance with these rules, similar rules have also been drafted by global various countries.The also stranger RoHS of the European Union environmental protection for vast Chinese Consumer's of this is instructed, be known as " instruction that affects the global manufacturing nerve ", its related product scope is extremely extensive, comprise nearly 200,000 kinds of 10 big classes, all electronic information series products have almost been contained, as big small household appliance, IT and communication facilities, electric appliance and electronic instrument, toy leisure and sporting equipment, Medical Devices etc.
