Manufacturing Quality Control of 7381-30-8
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration standard using internal or external standardization. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in methanol-based reagent. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Determines free acidic impurities by titration with standardized sodium hydroxide using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis after High-Temperature Ashing | Measures non-volatile inorganic residue remaining after combustion at 700-800 C in a muffle furnace. |
| Color | Visual Comparison Against Platinum-Cobalt Scale | Evaluates liquid color intensity by matching sample appearance to standardized Pt-Co color solutions in Nessler tubes. |
| Density at 20 C | Digital Density Meter (Oscillating U-tube principle) | Determines mass per unit volume based on resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index at 20 C | Abbe Refractometer | Measures bending of light passing through sample to determine refractive index, correlated with purity and composition. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Quantifies total heavy metals after acid digestion by measuring absorbance of ground-state atoms in flame or graphite furnace. |
| Volatile Impurities | Headspace Gas Chromatography-Mass Spectrometry (HS-GC-MS) | Identifies and quantifies low-boiling volatile contaminants via thermal equilibrium headspace sampling and mass spectral detection. |
| Silicon Content | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Measures total silicon concentration by detecting characteristic atomic emission lines after plasma atomization and excitation. |
| Appearance (Clarity) | Visual Inspection in Clear Glass Container | Assesses physical clarity and presence of suspended particles or haze against white background under controlled lighting. |
