| Biological Staining | Microscopic sample staining to enhance visibility of cellular structures | Drop staining or immersion after fixation |
Manufacturing Quality Control of 15876-47-8
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (C20H12O4N2Na2) | UV-Vis Spectrophotometry | Measures absorbance at characteristic wavelength (approx. 505 nm) in alkaline medium and calculates concentration using Beer-Lambert law and certified reference standard. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metal content by atomizing sample in flame or graphite furnace and measuring absorption of specific elemental wavelengths. |
| Arsenic | Hydride Generation-AAS (HG-AAS) | Converts arsenic to volatile arsine gas, which is swept into quartz cell for AAS detection at 193.7 nm. |
| Lead | Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) | Atomizes and excites sample in plasma; measures intensity of Pb emission lines (e.g., 220.353 nm) for quantification. |
| Sulfated Ash | Gravimetric Analysis | Ignites sample at 600-700 C after sulfuric acid treatment; weighs residual inorganic ash as percentage of original sample. |
| Chloride | Potentiometric Titration with AgNO3 | Titrates chloride ions with standardized silver nitrate solution using silver indicator electrode; endpoint detected by potential inflection. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemically generates iodine in titration cell; water reacts stoichiometrically with iodine, enabling precise quantification. |
| pH (1% aqueous solution) | pH Potentiometry | Measures hydrogen ion activity using calibrated glass electrode in a 1% w/v aqueous solution of the dye. |
| Solubility in Water | Visual Inspection and Filtration | Evaluates complete dissolution of specified amount in distilled water at 20 C; absence of undissolved particles or haze indicates compliance. |
| Related Substances (Impurities) | High Performance Liquid Chromatography (HPLC) | Separates components on reversed-phase column; detects and quantifies impurities via UV absorbance relative to main peak. |
| Loss on Drying | Thermogravimetric Gravimetry | Determines weight loss after drying sample at 105 C for 2 hours; reported as percent mass loss. |
| Color Strength (Relative Absorbance) | UV-Vis Spectrophotometry | Compares absorbance of test solution to that of reference standard under identical conditions; expressed as percentage of declared strength. |
