X-ray diffractometer, Scanning electron microscopy, vibrating sample magnetometer and Thermogravimetric analysis
For XRD powder diffraction you need about 1 g of sample with particle sizes no smaller than 50 microns. You can use less, but just ensure the sample is of a good representation of the bulk material.
For SEM, I believe the maximum horizontal would be around 10 cm with a vertical of 40 mm, but I believe this is very dependent on your equipment model.
For TGA, 10 mg-1 g is a good estimate. I believe it's better to be on the higher end of that range though for better results (0.5-0.75 g).
For DSC, 0.5-100 mg is sufficient.
I've never done VSM before though.. Sorry to not be of help for that question.
If your sample is in powder form, you will need 50 mg for SEM, 1 gr for VSM, and 1 gr for XRD measurements.
Sometimes it depends on the type of the used instruments, so you may better ask the operators of these instruments.
Good answer from Fatma Zohra Benabid
Different devices need different amounts of the sample.
But 1 g for XRD is too much, even if you use the old techniques. 50 -100 mg is enough.
As for vibrating magnetometer, I think that 200 mg will be quite enough; for example, we have obtained good results using exactly 200 mg of samples of Ni nanopowders.
Taking into account answer above, we can conclude that 1 g of sample will be enough for all needed tests.
With kind regards,
