| Test Item | Common Test Method | Method Summary |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, state, and clarity under natural or standard lighting; it should be a colorless to slightly yellow transparent liquid. |
| Colority | Platinum-Cobalt Colorimetric Method (GB/T 3143 or ASTM D1209) | Compare the sample with standard platinum-cobalt solutions to determine its color value (expressed in Hazen units), assessing color changes caused by impurities. |
| Purity / Main Component Content | Gas Chromatography (GC) | Quantitative analysis using capillary column GC with FID detector, via internal standard or area normalization method, to determine the content of the target compound. |
| Moisture Content | Karl Fischer Titration | Determine water content by potentiometric or coulometric titration; suitable for trace moisture detection (typically required ≤0.1%). |
| Acid Value | Acid-Base Titration (GB/T 6365 or ASTM D974) | Titrate free acids in the sample with potassium hydroxide in ethanol solution; results expressed as mg KOH per gram of sample, indicating degree of oxidation or hydrolysis. |
| Refractive Index | Abbe Refractometer Method (GB/T 614 or ISO 5661) | Measure the refractive index of the sample at a specified temperature (e.g., 20°C), used as an auxiliary parameter for assessing purity and consistency. |
| Density | Density Meter or Oscillating U-tube Method (GB/T 4472) | Measure liquid density at standard temperature; one of the physical property indicators used for quality consistency control. |
| Residual Solvents | Headspace-Gas Chromatography (HS-GC) | Detect organic solvents possibly remaining from manufacturing (e.g., toluene, acetone) using headspace sampling coupled with GC-FID or GC-MS. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After digestion, measure total content of heavy metal elements such as lead, arsenic, cadmium, and mercury to ensure compliance with pharmacopoeia or industrial standard limits. |
| Residue on Ignition / Ash Content | Gravimetric Method (GB/T 7531) | Weigh the inorganic residue after high-temperature ignition of the sample to reflect the level of inorganic impurities. |
