Manufacturing Quality Control of DIPHENYL PHTHALATE
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | Samples are separated using a reversed-phase chromatographic column, and the main component purity is quantified using a UV detector (e.g., at 254 nm), suitable for high-precision content determination. |
| Content Determination | Gas Chromatography-Mass Spectrometry (GC-MS) | After dissolution in an appropriate solvent, the sample is injected and separated via a capillary column; the mass spectrometer detector enables qualitative and quantitative analysis with high sensitivity, ideal for trace impurity analysis. |
| Impurity Identification and Limit Testing | Liquid Chromatography-Mass Spectrometry (LC-MS) | Used for structural identification and semi-quantitative analysis of unknown or complex impurities, particularly suitable for thermally unstable or non-volatile impurities. |
| Residual Volatile Organic Compounds | Headspace Gas Chromatography (HS-GC) | Employs headspace sampling technology to avoid matrix interference, used for detecting solvent residues (e.g., benzene, toluene), complying with pharmacopoeial or environmental standards. |
| Water Content | Karl Fischer Titration | Determines trace amounts of water in samples via coulometric or volumetric methods; simple to operate with high accuracy, commonly used for moisture control in chemical raw materials. |
| Melting Point Determination | Capillary Melting Point Apparatus | Measures the melting temperature range based on the physical properties of the substance to assess crystalline purity and batch consistency. |
| Appearance and Color | Visual Color Comparison / Colorimeter | Observes solid color or solution clarity under standard lighting, or quantifies L*a*b* values using a colorimeter to control product appearance quality. |
| Residual Heavy Metals | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After acid digestion, elements such as lead, cadmium, mercury, and arsenic are measured with sensitivity down to the ppb level, meeting RoHS or pharmacopoeial limit requirements. |
