Manufacturing Quality Control of Methyl cellulose
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Neutralization of carboxyl groups in hydrolyzed sample with standardized NaOH solution using phenolphthalein indicator. |
| Moisture Content | Karl Fischer Titration | Quantitative reaction of water with iodine and sulfur dioxide in pyridine/methanol medium, measured potentiometrically. |
| Viscosity (4% aqueous solution) | Rotational Viscometry | Measurement of resistance to flow under controlled shear rate using a calibrated rotational viscometer at 20 C. |
| pH (1% aqueous solution) | Potentiometric pH Measurement | Determination of hydrogen ion activity using calibrated glass electrode in a standard 1% w/v aqueous dispersion. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals after wet digestion by measuring absorbance of ground-state atoms at characteristic wavelengths. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 500-600 C followed by treatment with sulfuric acid and final weighing of residual inorganic sulfate ash. |
| Degree of Substitution (DS) | Gas Chromatography (GC) of methyl iodide derivatives | Derivatization to methyl iodide, separation by GC, and quantification relative to calibration standards. |
| Residue on Ignition | Gravimetric Analysis | Weighing mass loss after ignition at 600 C; residue represents inorganic impurities. |
| Chloride Content | Potentiometric Titration with AgNO3 | Titration with silver nitrate using silver indicator electrode to detect endpoint of AgCl precipitation. |
| Microbial Limits | Membrane Filtration and Plate Count | Filtration of aqueous solution, transfer to selective agar media, incubation, and colony enumeration. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to calculate volume-based size distribution. |
| Bulk Density | Graduated Cylinder Method | Mass of freely poured sample divided by its unsettled volume in a standardized cylinder. |
