![]() ![]() ![]() ![]() The resulting diffractograms were easy to sort out (both were halite - common salt)! Amazing. As you can see from the photos I didn't even have enough to fill the depression. I ran the *gently* crushed powders on a zero bg holder that has a 4 mm diam x 100 μ deep depression in the middle of a round holder. The top of the sample holder is covered by Kapton film and tightened by PTFE O-ring. Zero diffraction plate with the option of OD 24.6, and 32 mm, which is put inside of the stainless steel holder. Here's the latest and most demanding application: I was given two vials of "yellow" and "white" grains to identify, total amount somewhere around a half to two grains of table salt (probably < 1 mg - the samples are from Antarctica and we can't easily get more). AT-XRD-XX is an air-tight sample holder of a zero diffraction plate for powder XRD. It's really been the most scientifically useful holder so far. When I put together the initial MiniFlex order I must have really guessed right when ordering the zero-background holder. One area in which the Rigaku MiniFlex seems to be a hit is identifying very small amounts of (geo)material.
