应用莱曼(Raman)光谱方法只要取少量制剂样品不经分离就可测得较精确的定量结果。过去用UV 法测定未经分离的样品,因醋氨酚和苯丙醇胺的UV 谱几乎完全重叠而不能测定;而其IR 光谱和莱曼光谱则几不重叠。即使在商品感冒药Sineaid~(?)中醋氨酚比苯 Using Raman spectroscopy, you can obtain more accurate quantitation results by taking a small sample of the sample without isolation. In the past, the non-isolated sample was determined by the UV method because the UV spectra of acetaminophen and phenylpropanolamine almost completely overlapped each other and could not be measured. However, the IR and Lyman spectra were not overlapped. Acetaminophen even in the commercial cold medicine Sineaid ~ (?) Than benzene
