Constituent of “Panacetin” Recrystallization& Melting-Point Measurement Organic Chemistry Lab Introduction: Panacetin purportedly includes sucrose‚ aspirin‚ and acetaminophen. However‚ the accuracy of Panacetin’s contents has been called into question by the Association for Safe Pharmaceuticals. Therefore‚ the lab must discover the accuracy of the ingredients listed on Panacetin’s label. The unknown in this experiment is presumed to be something

Objective: The goal of the experiment was to use UV/VIS spectroscopy to collect data to quantify acetaminophen‚ aspirin‚ and caffeine from a migraine tablet where there is heavy spectral interference using Target Factor Analysis1. The migraine tablet has other ingredients in it like FD&C blue #1‚ stearic acid‚ and saccharin. Saccharin is the ingredient thought to have the biggest interference and was used as the experimental basis2. Instruments: UV/VIS spectroscopy was used to analyze the absorption

Analysis of Food Dyes in Beverages Samantha Sequito and Anna Steenland Lab Performed: December 3‚ 2013 Lab Due: December 13‚ 2013 Introduction: Different amounts of FD&C Blue I were diluted with water to make eight differently concentrated 10 mL solutions. Samples were placed in the spectrophotometer to determine the percent transmittance of FD&C Blue 1. All of the data was summarized in graphs to predict the concentration of FD&C Blue I in a sample of Gatorade.

Blood Gas Analysis at the Core Laboratory at University Hospital‚ London‚ Ontario. Blood is one of the most important fluids in the human body. It helps carry nutrients such as oxygen to the cells in the body and transports out wastes like carbon dioxide and other metabolites from these cells. Since blood is the medium through which the different organs and tissues in our body communicates‚ keeping a close eye on the constituents of a blood sample would provide a good indication of the functioning

the first 2 tubes. Add 1 drop of 1% ferric chloride solution to each tube. Shake and note color. If impure‚ red to violet color will appear. Melting point can be used to test for purity. Melting point from a dry sample should be 135-136°C for pure aspirin. There are impurities if much less than that.
