Gas chromatography and mass spectrometry analysis is a widely used method for assessing the quality of essential oils due to its ability to separate and identify the various components present in the oils. This technique provides detailed information on the chemical composition of essential oils, including the presence and concentration of different compounds, which is crucial for determining their purity and therapeutic properties.

Gas chromatography works by vaporizing the essential oil and passing it through a column, where components are separated based on their volatility and interactions with the column's material. Mass spectrometry then identifies these components by measuring the mass-to-charge ratio of ions produced from the sample, allowing for precise identification and quantification.

This combination of techniques is particularly valuable in the aromatherapy field, as it helps practitioners ensure that the essential oils they use are of high quality, free from contaminants, and possess the expected therapeutic effects. Other methods, while useful in different contexts, may not provide the same level of detail or specificity in identifying essential oil constituents.
