Components | Performed on: Wednesday‚ May 8th‚ 2013 | | | 5/15/2013 | | Introduction: The goal of this experiment was to identify an unknown analgesic drug through the use of thin-layer chromatography. The drugs used were‚ Unknown #1‚ caffeine‚ aspirin‚ and acetaminophen. Thin-Layer Chromatography is a technique for identifying substances using a mobile phase (developing solvent) that draws up through a stationary phase (TLC plate) and marks spots of differing distances for differing

Energy drinks typically have an eyebrow-raising amount of caffeine and sugar. It is also noted that they do not fall into any issues against FDA or USDA regulations‚ by default (FDA.gov‚ par. 4). This is due to the fact that all ingredients‚ as they are listed in their basic names‚ are not required to list their attributes. For example‚ “Guarana” is listed ingredient but is simply another source of caffeine. As such‚ despite passing preliminary product requirements‚ there are unforeseen

Coffee can have a stimulating effect on humans due to its caffeine content. It is one of the most-consumed beverages in the world.

place. These substances can affect the pulsation of the Lumbriculus. Lumbriculus were tested with two secondary plant compounds‚ caffeine and nicotine‚ to determine the effects of these drugs on their pulse rate compared to the control‚ water. Caffeine often created a diuretic agent from plants which could affect water balance (Dearing et al‚2002). When caffeine is consumed it attaches itself to brain cell receptors‚ which blocks adenosine‚ a chemical that makes you sleepy. This blocking of

Even though coffee and tea are distinctly different drinks they both have a story of how they were discovered‚ levels of caffeine and must be prepared before drinking. Coffee and tea have been around for many years and both have wise tales of how they were discovered. Ethiopia is the original home of the coffee plants.

Experiment 3: Separation of the Components of a Mixture General Chemistry 101 (CHEM 101)‚ ISP SCUHS Report 2 September 15‚ 2013 Abstract Mixtures are made up of substances or components. If the mixture is fairly uniform in composition‚ properties‚ and its overall appearance‚ it is homogenous. If the component parts are clearly separated‚ it is heterogeneous. In order to identify the components in a mixture‚ methods must be used to sort out the components. However‚ the same methods will not

FE 315 INSTRUMENTAL ANALYSIS High Performance Liquid Chromatography (HPLC) Instructor: Dr. Hüseyin BOZKURT High Performance Liquid Chromatography (HPLC) is one mode of chromatography‚ the most widely used analytical technique. Chromatographic processes can be defined as separation techniques involving mass-transfer between stationary and mobile phases. Present day liquid chromatography that generally utilizes very small packing particles and a relatively high pressure is referred to as high

presented with three water-filled glass containers and challenged to assign each container to a selection of choices: tap water‚ traditionally treated wastewater‚ and purified sewage water. This test is obviously to prove the quality of the facility’s purification process because the purified sewage water is aesthetically the cleanest and purist. After this demonstration‚ Heffernan was immediately engaged and supportive of the San Diego AWPF’s mission and project. She also explains that because of the reoccurring
