The spectral bandwidth is one of the main factors that affect the quantitative analysis error of UV/Vis Spectrophotometer. After studying the influences of spectral bandwidth on the analysis error, T. Owen pointed out that the spectral bandwidth of the T8DCS UV/Visible Spectrophotometer is very important. When the spectral bandwidth (SBW) / natural bandwidth (NBW) ≤ 0.1 (natural bandwidth, which is the half-width of the sample absorption band), the instrument can meet the requirements of 99% sample analysis, and analysis accuracy can reach up to 99.9%. Below is an application example in the drug inspection industry:
As we can see, the peak value is the highest when the spectral bandwidth is 0.4nm, indicating that the best spectral bandwidth is 0.4nm. In addition, the most suitable spectral bandwidth for drugs, such as Penicillin Potassium and Cytochrome C solution, can be found through experiments. Thus reducing the measurement steps, reducing testing costs, and saving measurement time. The T8DCS features an advanced continuous variable bandwidth and excellent performance. It meets various demands for spectral bandwidth from users in different industries especially the pharmaceutical industry and scientific research field.
