Gas chromatography (GC) separates the complex mixture into individual chemical compounds. Mass spectrometry (MS) then identifies those compounds by breaking them into fragments and comparing their "fingerprints" to a known database. The Process : The oil is heated into a gas. : Helps determine the geographic origin of the plant
💡 : GC-MS is the "gold standard," but it can't always distinguish between isomers (molecules with the same atoms but different shapes). Sometimes, experts add a second step called Chiral GC to tell these twins apart. If you’d like more detail, let me know: Mass spectrometry (MS) then identifies those compounds by
: Measures the percentage of active therapeutic compounds (e.g., Linalool in Lavender).
: Each molecule is bombarded with electrons to break it into charged fragments.
: Analysts compare results against standard databases like NIST or Wiley.
