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.

Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid called the mobile phase‚ which carries it through a structure holding another material called the stationary phase. The various constituents of the mixture travel at different speeds‚ causing them to separate. The separation is based on differential partitioning between the mobile and stationary phases. Subtle differences in a compound’s partition coefficient result in differential retention

It was concluded that the product created was paracetamol when a thin layer chromatography test was performed and observed under ultraviolet light (which is discussed further down the page). An unknown substance was treated with acetic anhydrate and resulted with paracetamol. A compound that behaves in this matter is 4-aminophenol and is widespread in the industrial production of this drug. Upon these observations was the build up of “Chemical A” decided. When 4-aminophenol is t treated with

Determining the concentration of red dye #40 in an unknown solution Introduction: White light is composed of many different wavelengths of light combined together. A spectrophotometer is an instrument that shines a single wavelength of light of a known intensity into a solution and then measures the intensity of the light exiting the solution. If a solution contains

Ion Exchange Chromatography Week 10 TAG Question 1: Chapter 6-4 of your technique book provides a detailed description of how to run a ion- exchange column. Assume you have a cation-exchange column already prepared and ready to use. Create an outline of no more than 10 steps describing how you will regenerate the column‚ load your sample and collect the hydronium ion released. 1. Open the stopcock at the bottom of the column and allow solution to drain out until the solution level in the

8 - 15/16 02 June‚ 2016 Negative Side Effects of Hair Dye Products In this report‚ you’ll read about hair dye and its negative side effects. The first section of this report I explain the three main types of hair dyes. Next‚ the negative side effects of hair dye products are mentioned and elaborated. After that‚ safety tips and precautions are given. Finally‚ the conclusion will tie it all together. This is my research report on how hair dye products can cause various‚ life threatening side effects

Discussion Using the Thin Layer Chromatography experiment‚ caffeine was found to be the most polar due to the fact that it stayed closer to the stationary phase. Caffeine contains four amine groups that are extremely polar as a result of the hydrogen bond and amide functional group. Acetaminophen was found to be the second most polar analgesic drug tested. Acetaminophen contains a polar alcohol group on one side and amide group on the other but also includes non-polar functional groups that consisted
