Scope

After the polyquaternary ammonium salt sample is extracted with a mixed solvent of methanol, isopropyl alcohol, and saturated sodium chloride, the supernatant is filtered through a 0.45 μm microporous membrane, and measured using high-performance liquid chromatography-UV detection. The retention time is qualitative, and the external Quantification by standard peak area method.
