    Lab Report

    This experiment will separate the components of a mixture on the basis of their differing absorptive tendencies on a stationary phase, which is the method of chromatography. The mobile phase will consist of four distinct transition metal cations dissolved in an acetone-hydrochloric acid eluent, along with three unknown solutions; the identities of these will be determined based on a comparison of the Rf value of these to the known cations. First to be prepared was the stationary phase, or chromatographic

    Gsr Analysis

    Gunshot Residue Analysis You are provided with cotton balls that were used to swab 2 suspect’s hands for the presence of gunshot residue. Determine, by atomic absorption spectroscopy, if either of the 2 have fired a gun recently. To do this you will first extract the lead residue off of the cotton ball and then you will run the lead samples and a lead positive sample and a blank to determine if there is lead in the residue from the suspect’s hands. Extraction/Sample Prep: 1.) Use tweezers or forceps

    Chem Lab Report

    Statement of Goals The goal of the group project was to calculate the percent calcium in a natural calcium tablet from Prime Eastern Pharmaceuticals in order to compare it with the reported amount of 800 mg of calcium per tablet to determine the validity of complaints regarding a reduced amount of mineral in the multivitamin. The quantitative determination of the analyte was accomplished through three experiments: complexometric titrimetry, flame atomic absorption analysis, and potentiometry using

    Chromatography Lab Report

    Chromatography is commonly used to separate mixtures to determine different chemical components. The main types of chromatography include gas, thin layer, paper and column chromatography. Generally used most, paper has a stationery phase and a mobile phase in a chromatographical experiment. The stationery phase is the paper itself absorbing the solvent, while the mobile phase is the solute moving up the strip of paper. Solvents are solids, liquids or gasses that dissolve the solute, in this instance

    Accudata® Gts/Gts

    AccuData® GTS/GTS The Advantage test strip contains the enzyme glucose dehydrogenase which converts the glucose in a blood sample to gluconolactone. This reaction liberates an electron that reacts with a mediator. The oxidized form of the mediator hexacyanoferrate (III) accepts the electron, forming the reduced form of the mediator, hexacyanoferrate (II). The Advantage test strip employs the electrochemical principle of biamperometry. The monitor applies a voltage between two identical electrodes
