Experiment 1: TLC Analysis of Analgesic Drugs 1/23/2011 Purpose: The goal of this experiment is to test our knowledge and understanding of TLC analysis by having us do a TLC analysis of analgesics to figure out their main chemical components. Calculations: 1.) Rf = Distance spot traveled/ distance solvent traveled Results: Table 1: TLC Analysis Analgesic Drugs | Rf Value | Acetaminophen | 0.323 | Aspirin | 0.597 | Caffeine | 0.081 | Unknown 154 (Plate 1) | 0.081‚ 0.306‚ 0.597

1 A Geometric Approach to Strapdown Magnetometer Calibration in Sensor Frame J.F. Vasconcelos‚ Member‚ IEEE‚ G. Elkaim‚ Member‚ IEEE‚ C. Silvestre Member‚ IEEE‚ P. Oliveira Member‚ IEEE‚ and B. Cardeira Member‚ IEEE Abstract In this work a new algorithm is derived for the onboard calibration of three-axis strapdown magnetometers. The proposed calibration method is written in the sensor frame‚ and compensates for the combined effect of all linear time-invariant distortions‚ namely soft

A Comparison of Gravimetric Analysis and Volumetric Analysis To analysis the proportion of an element in a certain substance‚ the experiment could be done by gravimetric analysis and volumetric analysis‚ and these two methods of analysing could be occupied on several different purpose of experiments as well. In a specific experimental condition‚ there will be one method that is the most suitable to choose‚ and it is depending on the temperature‚ substance status‚ pressure and chemical properties

November 9‚ 2014 Madison Phillips Report Submitted: November 9‚ 2014 Title: Beers Law and Calorimetry Purpose: The purpose of this experiment is to apply Beer’s Law by analyzing samples provided by Q laboratory to determine their absorbance and prepare a Beer’s law plot. Molarity of these samples was also calculated to determine concentration and percent error rate. Students also analyzed the concentration of blue dye #1 to determine the concentration of blue dye #1 in a commercial blue dye drink

carry out the experiment. Firstly‚ varying the length of boiling might not be the best method to determine the amount of calcium ions. If time permits‚ I could perhaps investigate other variables such as pH‚ surface area and concentration and their effect on calcium leaching. Moreover‚ I could also use other types of fish soup stocks and compare to determine which soup has more calcium in it. Lastly‚ I have purchased “cleaned” anchovies from the supermarket to carry out this experiment‚ where the head

following questions. 1. What are the variables in this experiment? Identify the manipulated and responding variables and two controlled variables. The manipulated variable is light intensity. The responding variable is pH. Controlled variables include the initial pH‚ the size of the plant sprigs‚ and time. 2. How will you provide carbon dioxide to the evergreen sprigs? Carbon dioxide is provided by blowing into the BTB solution. 3. How will you know whether the carbon dioxide has disappeared

Retention time for caffeine : 4.149+4.142+4.152+4.1454 = 4.15 2. What is the retention time for benzoic acid? Retention time for caffeine : 2.651+2.817+2.857+2.9274 = 2.81 3. How are the retention times for caffeine and benzoic acid related to their chemical structure and the nature of the chromatographic system? The retention time of caffeine and benzoic are related due to the presence of a hydroxyl group. The hydroxyl
