Scanning Electron Microscope Sample

We do quite a few things here at EPI Materials Testing Group.

One thing we do quite a bit is taking pictures with our Scanning Electron Microscope (SEM). We are always doing something new, so you never know what you are going to see. Particularly when you are looking at a specimen at 30 times to 10,000 times magnification!

The picture below shows the surface of a metal coupon that had gone though some corrosion testing. Thankfully our client failed to clean the sample off all the way. The picture was taken at 1,500x magnification and the corrosion product on the sample is Iron Sulfide.

It turned out to be one of our favorite pictures of the year!
