| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, state, and presence of visible impurities under natural light or a standard light source. Applicable to solid or powder samples. |
| Melting Point | Capsule Melting Point Determination | Load the sample into a capillary tube and gradually heat it in a melting point apparatus, recording the initial and final melting temperatures to assess purity and material characteristics. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reverse-phase C18 column and a UV detector (e.g., 254 nm) to quantitatively determine the main component content using external standard or internal standard methods. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate the main peak and impurity peaks using gradient or isocratic elution, calculate the area of each impurity peak, and evaluate purity and impurity limits. |
| Water Content | Karl Fischer Titration | Determine water content in the sample using electrochemical titration. Suitable for trace moisture detection with accurate and reliable results. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight is achieved, and calculate the weight loss to assess volatile matter content. |
| Residue on Ignition | Residue on Ignition Method | Weigh the residual mass after incinerating the sample at high temperature (approximately 600–800°C) to evaluate inorganic impurity content. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Determine the content of heavy metals such as lead, cadmium, mercury, and arsenic after sample digestion to ensure compliance with pharmacopoeia or safety standards. |
| pH Value (Solution) | pH Meter Method | Prepare the sample as an aqueous solution of specific concentration (e.g., 1%) and measure its acidity or alkalinity using a calibrated pH meter. |
| Solubility | Solubility Test | Observe the solubility of the sample in water, ethanol, ether, or other solvents to determine if its physical properties meet the standard. |
