光声光谱法对粉末、凝胶等样品不用预处理就可直接进行测定。本文试以治疗溃疡病的美沙弗林(Methaphyllin,叶绿素铜钠、溴化普鲁本辛、三硅酸镁复合制剂)-乳糖混合粉末以及雷弗奴尔-氧化锌软膏,用可见区光声光谱法测定。配制不同含量的试样,测定它们的光声信号,用药品含量与光声信号作标准曲线,根据标准曲线用光声光谱法审定制剂中药品的定量。为了消除粒度对光声信号的影响,美沙弗林、乳糖和碳黑都经250目过筛。光声分光器光源为500W氙弧灯,连
Photoacoustic spectroscopy powder, gel and other samples can be directly measured without pretreatment. This article attempts to treat canker ulcer disease Methaphyllin (sodium copper chlorophyllin, bromide, the combination of magnesium bromide), and lactose mixed powder, and Reverol - zinc oxide ointment, with visible light photoacoustic Spectrometric determination. Preparation of different content of the sample, measure their photoacoustic signal, with the drug content and photoacoustic signal for the standard curve, according to the standard curve with the photoacoustic spectroscopy of the preparation of drugs in the quantitative. In order to eliminate the effect of particle size on photoacoustic signals, mesalalin, lactose and carbon black are both sieved through 250 mesh. Photoacoustic splitter light source for the 500W xenon arc lamp, and even
