Manufacturing Quality Control of DDE-OH
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against certified reference standard using a non-polar capillary column. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identification and quantification of structurally related impurities by retention time and mass spectral matching. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile organic solvents are partitioned into headspace and quantified using calibrated external standards. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water in the sample. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities (e.g., HCl, chlorinated acids) using phenolphthalein or potentiometric endpoint detection. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Multi-element detection after microwave-assisted acid digestion; based on element-specific mass-to-charge ratios. |
| Chloride Ion Content | Ion Chromatography (IC) with conductivity detection | Separation of anions on an ion-exchange column followed by quantitative detection via suppressed conductivity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature at which solid phase converts to liquid. |
| Appearance | Visual Inspection in Standardized Light | Assessment of physical state, color, and presence of particulates or foreign matter under controlled daylight-equivalent illumination. |
| Bulk Density | Graduated Cylinder Method (ASTM D1895) | Mass per unit volume measured by tapping a known mass of powder into a calibrated cylinder until volume stabilizes. |
| Particle Size Distribution | Laser Diffraction (Dry Dispersion) | Analysis of scattered light intensity patterns from dispersed particles to calculate size distribution based on Mie theory. |
| Residue on Ignition | Gravimetric Analysis after High-Temperature Ashing | Non-volatile inorganic residue determined by weight difference before and after incineration at 700-800 C. |
