| Industry | Application | Process |
|---|---|---|
| Healthcare & Medical | Nucleic acid staining for fluorescence microscopy | Dissolving acridine orange and preparing staining solutions at appropriate concentrations |
| Biological Research | Cell viability assessment | Staining with acridine orange followed by analysis via flow cytometry or fluorescence microscopy |
| Pharmaceutical Industry | Development of fluorescent labeling probes | Covalently conjugating acridine orange to specific molecules to prepare labeled probes |
| Environmental Monitoring | Microbial detection and enumeration | Applying acridine orange staining in conjunction with fluorescence microscopy for sample analysis |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Measures absorbance at characteristic wavelength (e.g., ~490 nm) and calculates concentration using Beer-Lambert law and reference standard calibration. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metal content by atomizing sample and measuring absorption of specific elemental wavelengths. |
| Water Content | Karl Fischer Titration | Determines water via stoichiometric reaction between water, iodine, sulfur dioxide, and base in methanol medium. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measures non-volatile inorganic residue after high-temperature ashing and subsequent weighing. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects chloride ions by titration with silver nitrate using silver indicator electrode; endpoint determined by potential change. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4, filters, dries, and weighs the precipitate to determine sulfate content. |
| Related Substances | HPLC-UV | Separates and quantifies structurally related impurities using reversed-phase chromatography and UV detection. |
| pH of Aqueous Solution | pH Potentiometry | Measures hydrogen ion activity in a standardized aqueous solution using calibrated glass electrode and pH meter. |
| Solubility in Water | Visual Observation / Filtration Test | Evaluates complete dissolution in specified volume of water at defined temperature and time, followed by visual inspection or filtration. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per pharmacopeial standards. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Oven Drying | Measures weight loss after drying under controlled temperature and vacuum/air flow to assess volatile content. |
| Microbial Contamination | Membrane Filtration and Plate Count | Detects viable aerobic microorganisms by filtering sample, culturing on nutrient agar, and enumerating colony-forming units. |
