Manufacturing Quality Control of Polyquaternium-28
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Active Content | Acid-Base Titration | Quantifies quaternary ammonium groups by back-titration with standardized acid after reaction with excess KSCN. |
| pH | Potentiometric Measurement | Measures hydrogen ion activity using calibrated pH electrode in aqueous solution. |
| Viscosity | Rotational Viscometry | Determines resistance to flow under controlled shear rate using spindle-type viscometer. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against standard reference under controlled lighting. |
| Water Content | Karl Fischer Titration | Quantifies water via iodine-sulfur dioxide redox reaction in anhydrous methanol medium. |
| Heavy Metals | ICP-OES | Detects trace metal impurities (e.g., Pb, Cd, Hg) by atomic emission after acid digestion. |
| Chloride Ion Content | Argentometric Titration | Measures Cl- by precipitation titration with standardized AgNO3 using potentiometric or chromate endpoint. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after high-temperature ashing and weighing. |
| Molecular Weight Distribution | Gel Permeation Chromatography | Separates polymer chains by hydrodynamic volume and compares retention times to polystyrene standards. |
| UV Absorbance at 220 nm | UV-Vis Spectrophotometry | Measures absorbance related to conjugated or aromatic impurities in diluted aqueous solution. |
| Density | Oscillating U-Tube Densitometry | Determines mass per unit volume from resonant frequency of filled U-shaped glass tube. |
| Microbial Contamination | Membrane Filtration | Quantifies viable aerobic microorganisms by filtration, membrane transfer, and colony enumeration on agar medium. |
