紫外分光光度法在混合物分析中的应用受到很大限制,主要是组分的吸收谱带宽且常重叠,影响定量测定。高通数字滤波法(High pass digital filtering)是一种数据处理方法,可以选择性滤去光谱中的低频成分,适合于有宽干扰吸收峰存在时混合物的定量分析。高通数字滤波法的主要原理为,先用一二项式滤波器平滑紫外光谱,同时用一固定波长的步长使谱数字
UV spectrophotometry in the application of mixture analysis is greatly limited, mainly the absorption spectrum of the components of the bandwidth and often overlap, affecting the quantitative determination. High pass digital filtering is a data processing method that selectively filters out low-frequency components of a spectrum and is suitable for quantitative analysis of mixtures in the presence of a wide interfering absorption peak. Qualcomm digital filtering method is the main principle, first with a binomial filter to smooth the UV spectrum, while using a fixed wavelength step size spectrum
