溶出度自动分析仪器问题
|
||
|
各位大神， 如下描述的的自动分析仪器检检溶出的设备，有了解的嘛？ 是溶出紫外一体机嘛？ 求指教！ Apparatus: Automatic analyzer consisting of (1) a liquid sampler, (2) a proportioning pump, (3) suitable spectrophotometers equipped with matched flow cells and analysis capability at 480 nm, (4) a means of recording spectrophotometric readings, and/or computer for data retrieval and calculation, and (5) a manifold consisting of the components illustrated in Figure 1. Analysis: With the sample line pumping water, the other lines pumping their respective reagents, and the spectrophotometer set at 480 nm, standardize the system until a steady absorbance baseline has been established. Transfer portions of the Standard solution and the Sample solution to sampler cups, and place in the sampler. Start the sampler, and conduct determinations of the Standard solution and the Sample solution typically at the rate of 40/ h using a ratio of about 2:1 for sample and wash time. Calculate the percentage of the labeled amount of ampicillin (C16H19N3O4S) dissolved: Result = (AU/AS) × CS × V × P × F × (1/L) × 100 AU = absorbance of the Sample solution AS = absorbance of the Standard solution CS = concentration of USP Ampicillin RS in the Standard solution (mg/mL) V = volume of Medium, 900 mL P = potency of ampicillin in USP Ampicillin RS (μg/mg) F = conversion factor, 0.001 mg/μg L = label claim (mg/Capsule) |
