how much amount of CNTs needed for SEM, EDS, XRD, FTIR, TGA? how to find out purity of CNTs using TGA?
For sem very minimal amount than a pinch of salt
same as EDS
for XRD u should give 1.5 g as minimum u should give atleast 2grams. many institute prefers large quantity because of substrate widhth
FTIR minimum 50mg
TGA u can give how much u want u give they wil take in mg only for example 5-20mg
from weight loss curve u can conclude that ur sample is
stable.
The amount of sample required for SEM, EDS, XRD, FTIR, and TGA analysis of carbon nanotubes will depend on the specific experimental conditions and the sensitivity of the instruments used,
- SEM: For SEM analysis, a very small amount of sample is required, typically in the range of a few milligrams or less.
- EDS: For EDS analysis, the sample size can vary depending on the desired spatial resolution and the sensitivity of the instrument. Generally, a sample size of a few milligrams or less should be sufficient.
- XRD: For XRD analysis, a larger sample size is typically required, in the range of 10-100 milligrams or more, depending on the instrument sensitivity and the desired level of detail. The sample should be finely ground and homogenized before analysis.
- FTIR: For FTIR analysis, a small amount of sample is typically required, in the range of a few milligrams or less. The sample can be dispersed in a suitable solvent or pressed into a thin film for analysis.
- TGA: For TGA analysis, a larger sample size is typically required, in the range of 10-100 milligrams or more, depending on the instrument sensitivity and the desired level of detail. The sample should be finely ground and homogenized before analysis.
Important Note
The specific amount of sample required may vary depending on the specific experimental conditions and the sensitivity of the instruments used.
