Manufacturing Quality Control of FEMA 3498
| Detection Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, and presence of suspended particles or precipitates under natural light or standard illumination. |
| Color | Platinum-Cobalt Colorimetric Method (APHA) | Use standardized platinum-cobalt solutions for comparison to determine the color grade of liquid samples, assessing purity and oxidation level. |
| Refractive Index | Refractometry | Measure at a specified temperature (e.g., 20°C) using an Abbe refractometer, used for identification and purity assessment. |
| Relative Density | Density Bottle Method or Electronic Density Meter | Determine mass per unit volume to verify consistency and purity of the substance. |
| Acid Value | Acid-Base Titration | Titrate free acids in the sample with standardized sodium hydroxide solution; calculate milligrams of KOH consumed per gram of sample to assess hydrolysis degree. |
| Ester Content | Saponification followed by Back Titration | Add excess standard alkali, heat to saponify, then back-titrate with standard acid to determine ester content. |
| Purity Analysis | Gas Chromatography (GC) | Separate components using capillary columns and quantitate main constituents and impurities via FID detection—primary method for purity control. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detect organic solvents (e.g., methanol, acetone) remaining from production processes to ensure compliance with pharmacopeial or food safety standards. |
| Moisture Content | Karl Fischer Titration | Utilize the reaction between iodine and sulfur dioxide in a pyridine/methanol system with water, enabling precise measurement of trace moisture. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, measure levels of lead, arsenic, mercury, cadmium, and other heavy metals to ensure they meet safety limits. |
| Structural Confirmation | Fourier Transform Infrared Spectroscopy (FTIR) | Analyze characteristic absorption peaks of functional groups to confirm the presence of ester groups, double bonds, etc., in the molecular structure. |
| Molecular Structure Verification | Nuclear Magnetic Resonance Spectroscopy (NMR) | Provide detailed carbon-hydrogen framework information through ¹H-NMR and ¹³C-NMR for definitive confirmation of chemical structure. |
| Volatile Impurities | GC-MS Coupled Technique | Combine gas chromatography separation with mass spectrometry structural identification capability to detect, identify, and quantify unknown volatile impurities. |
