Answer:
Measuring carbon isotopes is an extremely useful technique, but until now, it has found limited use because of the cost,” said Long. “Lowering the cost will open the way for new applications, especially ones that require testing a large number of samples.”

Combustion Analysis
Explanation:
The methodology of carbon compound is as follows -
- Combustion analysis (CHNSO) using CHNS(O) analyzer
- CHNSO is an analysis of the amounts of Carbon (C), Hydrogen (H), Nitrogen (N), Sulfur (S) and Oxygen (O)
- Total carbon is obtained and eliminated by burning the samples, while noncarbonate carbon is measured by treating with HCl
- Total carbon present in the black crusts is found to be composed of carbonate carbon, organic carbon, and elemental carbon
2. Differential and gravimetric thermal analysis (DTA-TGA)
- This method reveals that the main atmospheric deposition elements are -carbon and sulfur that are present in the deterioration layers on the stone buildings
- The results differentiate among carbonate, organic, and elemental carbon
