Evaluation of Paracetamol Content in Tablet Dosage Form Using UV-Spectrophotometry Casilagan‚ Camela Mae C.‚ and Jimenez‚ Joshua M. Chemistry Department‚ College of Science Adamson University Ermita‚ Manila 1.0 Introduction UV-Visible Spectrophotometry is a widely-used technique in Chemical and Pharmaceutical Analysis. And this method has been very useful both for Qualitative and Quantitative Applications‚ especially for organic compounds. Some of its advantages for Quantitative purposes

zero absorbance for the spectrophotometer. The direction of the test tube was marked and noted for future use. The student then selected a New Absorbance vs. Concentration experiment in SpectroPro. This was done in order to calibrate the spectrophotometer. The wavelength setting was set on the spectrophotometer at 620nm and the machine was set absorbance‚ listed as unit (A). The student set the blank to zero absorbance and finished the calibration of the spectrophotometer. The solution in the

49.45%. Experiment 9 focuses on determining the different concentrations of potassium permanganate solutions by finding its absorbance through the use of spectrophotometer. Four known concentrations were prepared; 2.5 x 〖10〗^(-3) M‚ 6.25 x 〖10〗^(-4) M‚ 1.25 x 〖10〗^(-4) M‚ 6.25 x 〖10〗^(-4) M. The solutions were placed on the spectrophotometer to determine absorbance together with the unknown. Distilled water was placed before each trial to ensure the accuracy of results.

595nm. Using the BSA stock solution (2mg/mL=2000 ug/mL)‚ we prepared the concentration of the protein standard by carrying out serial dilution at 2x‚ 5x‚ 10x‚ 20x and 40x. The 2x dilution was made by mixing 250 uL of BSA and 250 of the homogenizing buffer. The solution was then vortexed for 10 seconds. A similar procedure with different concentration of BSA and stock solution was carried out to find the other diluted concentrations. After the dilutions were made‚ 200 uL of the BSA concentration from

for the reaction of Barley alpha-amylase and starch. The predicted optimum temperature and pH is 50-60 degrees Celsius and pH of 5-6. To test this hypothesis‚ a starch solution was mixed with the amylase and then tested for absorbance‚ using a spectrophotometer‚ at several different temperatures and pHs. From these experiments it was concluded that the optimum temperature was 55 degrees Celsius and the optimum pH was 5. these results lead to the conclusion that the Barley seed is best suited to be in
