Manufacturing Quality Control of Acid Blue 83
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place the sample on a white background and observe under natural light for color, physical state, and presence of impurities to determine whether it is a uniform blue powder or granules. |
| Shade and Strength | Spectrophotometry / Colorimetry | Prepare a dye solution of a specified concentration and measure absorbance at the maximum absorption wavelength (typically around 580–610 nm) using a spectrophotometer, comparing with a standard to evaluate shade and relative strength. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a UV detector (e.g., at 254 nm); identify the main component by retention time and quantify using peak area to determine the content of Acid Blue 83. |
| Moisutre Content | Drying Weight Loss Method / Karl Fischer Method | Drying weight loss method: Dry the sample at 105°C until constant weight and calculate the percentage weight loss; Karl Fischer method is suitable for trace moisture determination and provides higher accuracy. |
| Insoluble Matter in Water | Filtration and Gravimetric Method | Dissolve the sample in hot water, filter, wash the residue, dry, and weigh to calculate the content of insoluble matter in water. |
| pH Value | pH Meter Method | Prepare a 1% aqueous dye solution and measure pH directly at 25°C using a calibrated pH meter; the pH should typically be between 4.0 and 7.0. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After digestion treatment, determine the content of heavy metals such as lead, cadmium, chromium, and mercury to ensure compliance with environmental and safety standards (e.g., Oeko-Tex® requirements). |
| Organic Impurities (e.g., Intermediates, By-products) | Thin-Layer Chromatography (TLC) or HPLC | TLC method: Observe the number of spots and Rf values after development; HPLC method allows more precise separation and quantification of individual impurity components. |
| Solubility | Solubility Test | Prepare an aqueous solution at a specified concentration (e.g., 10 g/L) and observe whether it dissolves completely without precipitation or turbidity. |
| Thermal Stability | Heating Test | Heat the sample at a specified temperature (e.g., 180–200°C) for a fixed duration (e.g., 30 min) and observe any color change or loss of strength. |
