Hello everyone,

I'm new in using XRF instrument and I need to invistigate any lead contamination in powdered samples  that should not exceed 10ppm of lead . However,  I need to makeup some sort of compostion as solid phase standard contains right concentration of lead. what condition is required ? any idea about to to make the right lead standard to calibrate the instrument ? some says grinding slice in lead salt or spike with dead solution !!

 

thanks in advance

Hi Sandy. It has been many years since I worked with XRF Spectrometry but when I needed to make a up a standard for a specific element I would use pure ground silica powder. After presenting a pellet of the pure silica to the machine, to verify if it contained any elements that might interfere, I would mixed weighted percentages of the element in question with the silica and thus produce a range of standards to calibrate against. I don't know just what XRF machine you are using but the one I used, this was in the early 1970's, it required the powdered sample to be pressed into a pellet. Don't know if my ancient experience will help you but there it is.
