Manufacturing Quality Control of Quinaldic acid
| Detection Item | Common Detection Methods | Method Overview |
|---|---|---|
| Appearance and Hue | Visual Comparison / Colorimeter | Compare color, gloss, and impurities with standard samples; use a colorimeter to measure L*a*b* values to assess color difference. |
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | Separate main components and impurities using reversed-phase HPLC, detect with a UV detector, and quantitatively analyze quinacridone content and related substances. |
| Crystal Structure | X-ray Diffraction (XRD) | Analyze characteristic diffraction peaks to identify different crystal forms such as α and β, ensuring the product meets application requirements. |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Disperse the sample in a liquid or gas medium and determine particle size and distribution based on laser scattering. |
| Thermal Stability | Thermogravimetric Analysis (TGA) | Measure mass changes of the sample under programmed temperature increase to evaluate decomposition temperature and thermal weight loss behavior. |
| Heat Resistance | Differential Scanning Calorimetry (DSC) | Determine phase transitions, melting, or crystallization temperatures to assess material stability during heating. |
| Solvent Resistance | Solvent Immersion Test | Immerse samples in solvents of varying polarity for a specified duration and observe changes in color, dissolution, or precipitation. |
| Impurity Elements | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Detect heavy metals or other inorganic impurity elements (e.g., Pb, Cd, Cr) in the sample to ensure compliance with environmental standards. |
| Moi sture Content | Karl Fischer Titration | Accurately determine moisture content in samples using titration, suitable for quality control of powders or moist materials. |
| pH Value (Dispersion) | pH Meter Measurement | Prepare an aqueous suspension of the sample and measure its acidity or alkalinity using a pH meter, reflecting surface treatment or residual substances. |
