CHE 333-03 11/21/16 Formal Report HPLC Determination of Caffeine in Analgesic Powders ABSTRACT: Components containing caffeine were composed into stock solutions. These solutions were diluted to 1: 10 substance: mobile phase. A stock solution of caffeine was diluted 1:50. A sequence of diluted caffeine solutions were prepared for use as a standard (ppm): 1, 2, 4, and 10. Solutions of acetaminophen, acetylsalicylic acid, and Goody’s Powder were developed to differentiate chromatographic peaks

In the essay “The Child and the Shadow,” author Ursula LeGuin utilizes techniques of Jungian psychology to connect the shadow of a young child to fantasy, and how this specific genre could be used to further develop this part of humanity. The speech begins with LeGuin summarizing a Hans Christian Andersen story about a man and his shadow. The man, desiring to enter the House of Poetry, tells his shadow to go on without him. His shadow departs from him, and both go their separate ways. Soon after

Societal Effects on the Macbeths Ambitions cloud the heads of those who then become irrational causing a loss of everything that makes one great. In Shakespeare’s The Tragedy of Macbeth the characters of Macbeth and Lady Macbeth chose crime and treachery over their own sanity creating a short lived life of guilt and misery. As the plot unfolds the dynamics of the couples’ broken relationship come to light with the lack of communication and plotting behind one another. With a brief appearance of

human serum [4, 9] and urine [4, 9]. Diazepam has been studied separately, in combination with other benzodiazepines and with other drugs [12-16]. It was studied in pharmaceutical form, blood and plasma [12-16]. These studies were carried out using analytical methods such as chromatography [13], HPLC [14,15], second-derivative spectrophotometry [5,16], fluorimetry [17], differential pulse polarographic determination [18] and capillary electrophoresis [19]. In this paper, we present the development

Abstract Gravimetric analysis describes the methods for finding the chemical constituent of analyte in a solution through analytical chemistry. This method uses the mass of solid SO42-, with an unknown quantity and quality, to qualitatively determine the makeup of the solid SO3-. Two separate experiments with the initial compounds of BaCl2 and SO42- were put into solution to allow for the BaSO4 precipitate to form. Through filtration and ignition of precipitate containing ashless papers

SEPERATION OF A MIXTURE Purpose: The purpose of this lab is to find out how components of a mixture can be separated and analyzed. Procedure: The procedure for this lab report is as follows: 1. Mixture is taken, and has to be measured in order to meet the requirements of 2-3g. 2. The mass of the tray is measured and then the scale is zeroed out and the mixture is added to find out the mass of the original mixture. 3. Next, find the mass of the 250mL beaker, zero out the scale

there is more concern about DXM determination in pharmaceutical dosage form. developing sensitive, simple, and rapid method for determination of DXM has been become an important target in control pharmaceutical dosage form. Therefore wide range of analytical methods for quantitation of DXM have been developed such as, high performance liquid Chromatography(HPLC) (Abdel-Moety, Al-Deeb, and Khattab 1995, Tedesco et al. 2013, Eichhold et al. 1997, Hoskins, Shenfield, and Gross 1997) (Abdel-Moety, Al-Deeb
