Manufacturing Quality Control of 928-51-8
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralization of acidic impurities (e.g., residual HCl) using standardized sodium hydroxide solution and potentiometric or visual endpoint detection. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled high-temperature incineration at 700-800 C. |
| Chloride Ion (Cl-) | Ion Chromatography (IC) | Separation and quantification of chloride anions using an anion-exchange column and suppressed conductivity detection. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after acid digestion by measuring absorbance of ground-state atoms at characteristic wavelength (283.3 nm for Pb). |
| Color | APHA Color Scale (Visual or Spectrophotometric) | Comparison of sample color intensity against platinum-cobalt standard solutions using visual matching or spectrophotometric absorbance at 455 nm. |
| Density | Digital Density Meter (Oscillating U-tube) | Determination of mass per unit volume based on resonant frequency shift of a vibrating U-shaped tube filled with sample. |
| Refractive Index | Refractometry | Measurement of light bending angle at air-sample interface using calibrated Abbe refractometer or digital equivalent. |
| Distillation Range | Simple Distillation with Thermometer | Determination of initial boiling point and 90% or 95% distillation temperature under controlled atmospheric pressure. |
| Aldehyde Impurities | UV-Vis Spectrophotometry (after derivatization with DNPH) | Derivatization of aldehydes to hydrazones followed by measurement of absorbance at ~360 nm. |
| Residual Solvents (e.g., Hexane, Ethanol) | Gas Chromatography (GC) with FID or MS detection | Separation and quantification of volatile organic solvents using headspace GC with internal standard calibration. |
