This week’s photo is from my personal research and shows a precipitate that I generated in the lab one day of AgI (silver iodide) for analysis of 129I by accelerator mass spectrometry.
I felt though that I wanted to verify the purity of the AgI so I quickly threw in on our scanning electron microscope to a) check the chemistry and b) take a picture. The image below shows an amalgam of AgI crystals with a scale of 20 microns at 600 times magnification.
By the way, to any fellow Canadians reading this post. Please go vote today and be a part of our democracy!!
