Introduction to Electron Probe X-Ray Microanalysis (EPMA) by Dr Jeff Chen

Great job sir

[@dr-rock]

Thank you for the great presentation. Why the sample should be flat? Is it because of X-ray intensity difference depends on the beam direction?

[@jeffchen4016]

Correct! Surface tilt or roughness affects the length of the path of the X-rays have to travel within the sample. The longer the X-rays have to travel within the sample, the more they get absorbed, obviously the less would enter the X-ray detector. Vice versa.

I want to buy one for my lab but can't find it on the market can any one help

I suggest that you contact JEOL and Cameca, both of whom produce EPMA instruments.

Shimazu also makes e-probe if you are in Japan
