Manufacturing Quality Control of Diphenylmethane
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity | Gas Chromatography (GC) | Separates diphenylmethane from impurities using gas chromatography; purity is calculated by peak area normalization or internal standard method. |
| Main Content | High-Performance Liquid Chromatography (HPLC) | Uses reversed-phase HPLC with a C18 column and UV detector to quantitatively determine the main component content. |
| Moisture | Karl Fischer Titration | Quantitatively reacts Karl Fischer reagent with moisture in the sample; moisture content is determined by potentiometric titration. |
| Residual Volatile Organic Compounds | Headspace-Gas Chromatography (HS-GC) | Sample is heated in a sealed headspace vial to allow volatile components to enter the gas phase, followed by GC analysis for residual solvents. |
| Melting Point | Melting Point Determination | Measures the temperature at which the sample transitions from solid to liquid using a melting point apparatus or capillary method, to assess purity and consistency. |
| Appearance and Color | Visual Colorimetry | Observes sample appearance (e.g., clarity, presence of suspended matter) and compares color against standard color solutions under a standard light source. |
| Ash Content | High-Temperature Ashing | Sample is ashed at high temperature in a muffle furnace until constant weight; measures residual inorganic mass to evaluate inorganic impurities. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) | After sample digestion, AAS is used to determine the content of heavy metals such as lead, cadmium, mercury, and arsenic. |
