| 产品介绍 |
用于质量控制的制药二级标准品，为制药实验室和制造商制备内部工作标准品提供了一种方便、高性价比的替代方案。′这些二级标准品可追溯至USP、EP和BP一级标准品。
General Description Accurate analytic results in UV/VIS and infrared spectroscopy depend on the use of very pure solvents for sample preparation. The Uvasol solvents range has been specially designed for spectroscopy and other applications requiring solvents of the highest spectral purity. The refinement process allows a greater degree of security in applications and avoids misinterpretation of analytical results caused by traces of UV, IR and fluorescence contamination. Uvasol solvents offer best UV transmittance. In all specifications the minimum transmittance for 5 typical wavelengths are identified. |
