WitrynaIMPURITY IN PSEUDOEPHEDRINE-HCL RAW MATERIAL USING FT-IR ... The FT-IR absorption spectra of EP and PS in carbon tetrachloride showed that the spectra of both compounds are similar except at the wave number intervals 1450-850 cm-1 and 3260-2790 cm-1 (Fig. 2).

WitrynaEN 15376 limit the allowable concentrations of impurities in fuel ethanol and specify the test methods to be used. At present, the specified tests are time-consuming chromatographic and titrimetric methods, so a rapid spectroscopic method such as FT-IR could provide an attractive alternative. WitrynaXRPD), impurities (HPLC), residual solvents (GC), loss on drying (Ph.Eur), sulphated ash (Ph.Eur), heavy metals (Ph.Eur), assay (HPLC) and microbiological limit tests. The tests and limits in the specifications are considered appropriate for controlling the quality of this active substance. WitrynaYou can create known percent solutions of the sample, take the IRs, create a linear plot (beers law) and derive the equation of the slope to understand the relationship between peak area and concentration. Then you can test your unknown to the calibration curve to find the percent concentration (units of ppm) and calculate the purity. horse poppit
