Manufacturing Quality Control of 4519-17-9
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative separation and detection based on retention time and peak area relative to a certified reference standard. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Volatile impurities are equilibrated in headspace vial and quantified by GC-FID using calibration curves. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water in the sample. |
| Acid Number | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities using standardized sodium hydroxide solution with potentiometric endpoint detection. |
| Viscosity | Capillary Viscometry at 25 C | Measurement of flow time through a calibrated capillary tube under gravity, converted to kinematic viscosity. |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Comparison of sample color against platinum-cobalt standards using visual assessment or spectrophotometric absorbance at 430 nm. |
| Density | Digital Density Meter (Oscillating U-tube principle) | Determination of density from resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Refractometry at 20 C | Measurement of light bending angle at air-sample interface using calibrated Abbe refractometer. |
| Heavy Metals (as Pb) | ICP-OES after acid digestion | Sample digested in nitric acid, then elemental concentrations determined by atomic emission intensity in inductively coupled plasma. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separation of anions on ion-exchange column followed by quantitative detection via electrical conductivity. |
| Volatiles (Loss on Drying) | Gravimetric Analysis (105 C, 2 h) | Mass loss measured after drying under controlled temperature and time, indicating volatile impurities or solvents. |
| Residue on Ignition | Gravimetric Ash Test (500-600 C) | Non-volatile inorganic residue quantified after high-temperature ignition of sample in platinum crucible. |
