DEFINITION: Mass spectrometry (MS) is an analytical chemistry technique that helps identify the amount and type of chemicals present in a sample by measuring the mass- to-charge ratio and abundance of gas-phase ions.

PRINCIPLE: A mass spectrometer generates multiple ions from the sample under investigation This molecular ion undergoes. A method is presented for the chemical characterization of natural organic matter (NOM).

We combined reversed-phase chromatographic separation of NOM with high resolution inductively coupled plasma mass spectrometry. A desolvation technique was used to remove organic solvent derived from the preceding chromatographic separation.

They include the commercial processes of metal casting, infiltration of composites, and injection molding of polymers.

These processes may reside early in the process stream (e.g., ingot casting of wrought metallic products) or produce a finished component (e.g., a molded. An isotopic signature (also isotopic fingerprint) is a ratio of non-radiogenic 'stable isotopes', stable radiogenic isotopes, or unstable radioactive isotopes of particular elements in an investigated material.

The ratios of isotopes in a sample material are measured by isotope-ratio mass spectrometry against an isotopic reference process is called isotope analysis.
