紫外分光计 [光] ultraviolet spectrometer
- 方法:采用《中国药典》2005版附录收载的目视比较法、紫外分光光度法、色差计法进行测定。
Methods:The Comparison method by naked eyes, UV Spectrophotometry and Colourimetry methods in ChP 2005 were used. - 用紫外-可见分光光计测定了菁染料吸附在溴化银颗粒表面形成J-聚集体的反射光谱。
The reflection spectra of the J-aggregates of the mixed cyanine dyes and the corresponding independent cyanine dyes were measured by the use of UV-Vis spectroscopy. - 定期采集同一基地广东紫珠药材样品,采用紫外分光光度法测定按芦丁计的总黄酮含量。
Callicarpa kwangtungensis Chun samples is picked regularly in the same base, and total flavonoids content is tested according to rutin content index by UV spectrophotometry.
