Manufacturing Quality Control of 4524-93-0
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area comparison against certified reference standard. |
| Acid Value | Acid-Base Titration with NaOH | Measures free acid content via neutralization of acidic impurities using standardized sodium hydroxide solution. |
| Moisture Content | Karl Fischer Coulometric Titration | Determines water content based on electrochemical iodine generation proportional to water in the sample. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Chloride Content | Potentiometric Titration with AgNO3 | Quantifies chloride ions by argentometric titration using silver nitrate and a silver indicator electrode. |
| Color | Visual Comparison Against APHA Scale | Evaluates color intensity by matching sample appearance to standardized platinum-cobalt color solutions. |
| Density at 20 C | Oscillating U-tube Densitometry | Determines density from resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 C | Abbe Refractometry | Measures refractive index using critical angle of total internal reflection at prism-sample interface. |
| Boiling Point Range | Distillation with Digital Thermometer | Determines temperature range over which sample distills under specified pressure conditions. |
| Heavy Metals (as Pb) | ICP-OES after Acid Digestion | Quantifies total heavy metals following microwave-assisted nitric acid digestion and plasma optical emission detection. |
| Non-Volatile Residue | Gravimetric Evaporation | Measures residue remaining after controlled evaporation of a fixed sample volume under nitrogen stream. |
| Aldehyde Impurities | GC-MS with Derivatization | Detects and quantifies aldehyde impurities after derivatization with DNPH and separation/mass detection. |
