Thanks for reading!

An isotopic signature is like a unique fingerprint for atoms. It's all about the different versions of atoms that exist, called isotopes. These isotopes have different numbers of neutrons, which affects their weight. By measuring the ratio of different isotopes in a sample, scientists can determine where that sample came from or what processes it went through.

I remember now it’s a unique identifier. Thanks for explaining how it’s determined.
