The X-ray fluorescence Spectrometer could be divided to three types according to its design :
1) Desktop: Normally, the weight of deskstand type is heavy, and you need to connect with a seperate computers,the advantage of this instrument is repeatablity and stability is good. We used to recommend this type to gold shops, manufactories and labs.
2) Portable: small size, light weight, easy to carry,You also need to connect an external laptop. It's suitable for the people who needs to travel around and doing business in refining filed.
3) Hand-held: the smallest, lightest weight, no external computer, apparatus, built-in data display system, easy to take test. but the performance is not as good as the deskstand type's.
