| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Content Determination | Gas Chromatography (GC) | Utilizes capillary column gas chromatography with a flame ionization detector (FID) for quantitative analysis by comparison with reference standards; suitable for precise determination of volatile components. |
| Content Determination | Gas Chromatography-Mass Spectrometry (GC-MS) | Combines the separation capability of gas chromatography with the qualitative power of mass spectrometry to accurately determine the content of limonene and confirm its structure, commonly used for precise quantification in complex matrices. |
| Identification | Infrared Spectroscopy (IR) | Identifies structure based on characteristic absorption peaks of functional groups of limonene in the infrared region; confirms authenticity by comparison with standard spectra. |
| Identification | Nuclear Magnetic Resonance Spectroscopy (NMR) | Provides information on the chemical environment of hydrogen and carbon atoms in the molecule, used to verify the chemical structure of limonene, commonly applied for structural confirmation of high-purity samples. |
| Purity Check | High-Performance Liquid Chromatography (HPLC) | Although limonene is volatile, reversed-phase HPLC can be employed under specific conditions for impurity analysis and assessment of sample purity. |
| Impurity Analysis | GC-MS or GC-FID | Identifies and quantifies potential impurities such as synthetic by-products, degradation products, or isomers using retention times and mass spectral fragmentation patterns. |
| Residual Solvent Testing | Headspace-Gas Chromatography (HS-GC) | Used to detect residual organic solvents (e.g., ethanol, benzene derivatives) remaining from extraction or synthesis processes, ensuring compliance with safety standards. |
| Volatile Component Analysis | Gas Chromatography-Olfactometry (GC-O) | Combines sensory evaluation with GC separation to assess the contribution of limonene to the aroma profile, suitable for quality control in the flavor and fragrance industry. |
