Manufacturing Quality Control of BOC-HIS(TOS)-MERRIFIELD RESIN
| 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 under optimized chromatographic conditions. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of free carboxylic acid groups using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Ester Content | Gas Chromatography (GC) with internal standard | Quantification of ester moiety relative to a stable, non-interfering internal standard (e.g., methyl benzoate). |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled high-temperature ashing at 700-800 C. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after wet digestion, using lead as the limiting metal and air-acetylene flame. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and conductivity detection of chloride anions following aqueous extraction and filtration. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Measurement of yellowness index by comparing sample absorbance at 430 nm to APHA platinum-cobalt standard solutions. |
| Refractive Index | Refractometry | Determination of light bending angle at 20 C using a calibrated Abbe refractometer, correlated to purity and composition. |
| Specific Gravity | Pycnometry | Density measurement at 25 C via calibrated glass pycnometer filled with sample and weighed precisely. |
| Volatility Residue | Thermogravimetric Analysis (TGA) | Mass loss percentage measured upon heating from 25 C to 150 C under nitrogen, indicating low-boiling impurities. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of structurally related impurities (e.g.,庚二酸, ethanol, monoester) using reversed-phase C18 column and UV at 210 nm. |
