Manufacturing Quality Control of CARBOXYMETHYLCELLULOSE CALCIUM
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Calcium Content | EDTA Titration | Complexometric titration using EDTA at pH 10 with Eriochrome Black T indicator; calcium forms stable 1:1 complex with EDTA. |
| Carboxymethyl Substitution Degree (DS) | Acid-Base Titration | Back-titration of excess standardized NaOH after saponification of ester groups; DS calculated from consumed alkali. |
| Viscosity (2% aqueous solution) | Rotational Viscometry | Shear-dependent resistance to flow measured at specified temperature and shear rate using a calibrated rotational viscometer. |
| pH (1% aqueous solution) | Potentiometric Measurement | Hydrogen ion activity determined using calibrated pH electrode in a standard aqueous suspension. |
| Loss on Drying (LOD) | Gravimetric Analysis (105 C, 2 h) | Mass loss upon heating under controlled conditions reflects volatile content including moisture and residual solvents. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of lead after acid digestion and matrix-matched calibration; based on absorption of specific wavelength light by ground-state atoms. |
| Sulfated Ash | Gravimetric Analysis (500-600 C) | Residue mass after high-temperature incineration in presence of sulfuric acid; indicates inorganic impurity content. |
| Chloride Content | Potentiometric Titration with AgNO3 | Titration with silver nitrate using silver indicator electrode; endpoint detected by abrupt potential change due to AgCl precipitation. |
| Iron Content | ICP-OES | Quantification of Fe after microwave-assisted acid digestion; based on intensity of characteristic atomic emission lines. |
| Microbial Limits | Membrane Filtration and Plate Count | Viable aerobic microorganisms enumerated on soybean-casein digest agar after filtration and incubation. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern generated by dispersed particles to calculate size distribution based on Mie theory. |
| Assay (CMC-Ca Purity) | Non-aqueous Potentiometric Titration | Titration of carboxyl groups with tetrabutylammonium hydroxide in dimethylformamide using glass electrode; equivalence point detected potentiometrically. |
