Method for analyzing pure carbon

Click For Summary
SUMMARY

The discussion focuses on methods for analyzing pure carbon, particularly in its physical form. Key techniques mentioned include using a spectrometer or mass-spectrograph for analysis, which are reliable for identifying carbon presence. Additionally, burning the sample in pure oxygen to test for carbon dioxide is suggested, although this method is destructive. For crystalline forms of carbon, such as nanotubes or graphene, non-destructive testing using light or particle beams with a spectrometer is recommended.

PREREQUISITES
  • Understanding of spectrometry and mass-spectrography techniques
  • Knowledge of combustion analysis for carbon detection
  • Familiarity with non-destructive testing methods
  • Basic principles of crystalline structures in materials science
NEXT STEPS
  • Research the operation and applications of spectrometers in material analysis
  • Learn about combustion analysis techniques for carbon detection
  • Explore non-destructive testing methods for crystalline materials
  • Investigate the use of proton beams in elemental analysis
USEFUL FOR

Researchers, materials scientists, and chemists interested in carbon analysis techniques, particularly those working with physical and crystalline forms of carbon.

I have a sample on which I think carbon is formed physically but not chemically. What is an analysis technique to determine that there is carbon for sure?

Welcome to PF;
You have a black deposit on something?
You can analyse it with a spectrometer - or a mass-spectrograph.
Either is pretty sure.

You could burn it in pure oxygen and test for carbon-dioxide... (bubble though lime water)

what about a nondestructive test for carbon that's in a more crystalline form like nanotubes, graphene, etc? just curious, since in this case, you cannot burn it, mass spec it, or anything like that.
 
You use a spectrometer like I said: you shine something on the sample, like light or some sort of particle beam, and examine the spectrum of either the reflected or transmitted beam.

I have used 2 and 4MeV protons to determine the elements present in an unknown sample.
