| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Quantifies胆酸钠 based on absorbance at characteristic wavelength (e.g., 200-210 nm) using a calibrated standard curve. |
| Related Substances | HPLC with UV detection | Separates and quantifies structurally similar impurities (e.g., cholic acid, deoxycholic acid) using reversed-phase chromatography and UV detection. |
| Water Content | Karl Fischer Titration | Determines water by volumetric or coulometric titration using iodine-based reagent reacting stoichiometrically with water. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content after high-temperature incineration and weighing of residual material. |
| Heavy Metals | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Cd, As, Hg) via atomic emission from plasma-excited elements. |
| Chloride | Potentiometric Titration | Measures chloride ion concentration using silver nitrate titrant and silver/silver chloride electrode endpoint detection. |
| Sulfate | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 and determines content by weighing the dried precipitate. |
| pH (1% aqueous solution) | pH Potentiometry | Measures hydrogen ion activity using calibrated glass electrode in standardized aqueous solution. |
| Specific Optical Rotation | Polarimetry | Determines enantiomeric purity by measuring rotation of plane-polarized light in solution at specified concentration and path length. |
| Solubility | Visual Observation in Standard Solvents | Evaluates complete dissolution in water, ethanol, and methanol under controlled temperature and agitation conditions. |
| Microbial Contamination | Membrane Filtration and Plate Count | Detects and enumerates aerobic microorganisms using filtration, membrane transfer to culture media, and colony enumeration. |
| Endotoxin | Kinetic Chromogenic LAL Assay | Quantifies bacterial endotoxins via enzymatic cascade activation of Limulus amebocyte lysate, measured by color development rate. |
