Manufacturing Quality Control of L-Arginine L-aspartate
| Test Item | Common Testing Method | Method Description |
|---|---|---|
| Identification Test | Infrared Spectroscopy (IR) | Determine the infrared absorption spectrum of the sample and standard under identical conditions, compare characteristic peak positions to confirm structural consistency. |
| Thin Layer Chromatography (TLC) | Compare the migration behavior (Rf value) of the sample with the reference on a stationary phase for preliminary identification of amino acid types. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reverse-phase column (e.g., C18), UV or evaporative light scattering detector; quantify the main component content by retention time and peak area. |
| Amino Acid Analyzer Method | Based on ion-exchange chromatography and ninhydrin colorimetric reaction, specifically used for precise quantification of amino acids, suitable for high-purity sample analysis. | |
| Titration Method (for L-Arginine) | Leverage the basic property of L-arginine using non-aqueous acid-base titration (e.g., perchloric acid titration) to determine its content. | |
| Optical Rotation | Polarimetry | Dissolve the sample into a solution of certain concentration and use a polarimeter at sodium D-line (589 nm) to measure optical rotation and assess purity and configuration. |
| pH Value | pH Meter Method | Dissolve the sample in water and directly measure the pH of the solution using a calibrated pH meter to evaluate its acid-base properties against standards. |
| Water Content | Karl Fischer Method | Based on the quantitative reaction of iodine and sulfur dioxide in methanol with water, accurately determine the water content in the sample, suitable for trace water detection. |
| Residue on Ignition (Sulfate Ash) | Residue on Ignition Method | Ignite the sample at high temperature until constant weight is achieved, then determine the weight of residual inorganic matter to assess inorganic impurity levels. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Use gradient or isocratic elution to detect possible synthetic intermediates, degradation products, or other amino acid impurities. |
| Thin Layer Chromatography (TLC) | Semi-quantitative detection of organic impurities, simple and convenient method suitable for preliminary screening. | |
| Heavy Metals | Sulfide Colorimetric Method (Chinese Pharmacopoeia Method) | Under acidic conditions, heavy metals react with hydrogen sulfide to form colored precipitates; qualitative or semi-quantitative detection of lead, cadmium, and other heavy metals via colorimetry. |
| Microbial Limits | Microbial Limit Test Method | Includes total aerobic bacterial count, mold and yeast count, control organisms (e.g., Escherichia coli, Salmonella) testing to ensure sterility safety. |
| Bacterial Endotoxins | Limulus Amebocyte Lysate (LAL) Method | Utilize the reaction between limulus amebocyte lysate and bacterial endotoxins to produce gelation or color change for quantitative endotoxin detection. |
