Welcome to the Chemistry Research page. The Chemistry Department believe strongly in "teaching through research." For this reason, our department has acquired a significant amount of research grade instrumentation.
Abstract
This work was mainly to analyze the properties of the food dye Indigo Carmine (IC) for future examination in commercially consumed products. Different concentrations of IC were mixed with water by dilution and all concentrations were measured on the UV-Vis and the HLPC from a stock solution with concentration 3.2e-04 M to 1.005e-05, making five dilutions from the stock. The UV-Vis wavelength was used to determine the molar absorptivity of IC. This will help in its identification when testing for commercial products and with the instruments UV-Vis and HPLC concentrations could always easily be determined. The data also showed how the HPLC was more effective in measuring higher concentrations than the UV-Vis which could only produce smooth graph data under 1.6 absorbance.
