The retention time for Ibuprofen is 12.951 minutes‚ which was used to pick the correct peak that relates to Ibuprofen’s Mass Spectrometry spectra. The molecular mass of Ibuprofen from our MS spectrum is 206.0 g/mol. We continued the same process of determining the structure of Ibuprofen includes analyzing and subtracting the stable ion fragment peaks by the parent ion peak. The fragment peaks from our Ibuprofen spectrum are 161.2 g/mol‚ 119.2 g/mol‚ 107.2 g/mol‚ 91

Rf values where the given distance from origin to solvent front measures 59 mm: 1.) acetaminophen has a Rf value of 0.48; 2.) aspirin has a Rf value of 0.64; 3.) caffeine has a Rf value of 0.22; 4.) Biogesic® sample has a Rf value of 0.48 ; 5.) ibuprofen has a Rf value of 0.73; and 6.) mefenamic Acid has a Rf value of 0.76. Thus‚ the study shows that by having equal Rf values of about 0.48‚ Biogesic®’s most active component is acetaminophen (paracetamol)‚ a relatively polar compound having a molecular

Analgesics Krista Jinks CH 211L Section F 10/27/14 I. Abstract: The objective of this experiment was to analyze analgesic tablets by TLC to determine what analgesics they contain. The analgesics that could be in the tablets included ibuprofen‚ acetaminophen‚ aspirin‚ and caffeine. Through the use of TLC‚ unknown substance #62 was found to be Bayer Aspirin because it only contained aspirin. II. Introduction: 1. Briefly describe the process of Thin Layer Chromatography.

Chromatography – Analyzing Analgesics by TLC and Isolation of β-Carotene by Column Chromatography Introduction/Background: Flavonoids are an important group of additives that can be defined as pure substances either natural‚ extracted from raw materials or synthetic. Chromatography is the separation of two or more compounds or ions caused by their molecular interactions with two phases – one moving and one stationary (Weldegirma 2012). Three types of chromatography are used

As he comes off the field‚ an athlete notices he has a subtle pain in his shoulder. Determined to finish out the season strong‚ he takes two tablets of aspirin in hopes of healing the beginnings of an injury. What the athlete does not know about the painkillers could affect him later down the road‚ especially if he upholds his mentality of constantly taking aspirin whenever he senses an injury in the making. Painkillers are drugs that simply mask the pain many people suffer from on a daily basis

We define chromatography as the separation of two or more compounds or ions by

solvent is the key factor for the compound to travel with it or stay in stationary phase. The result show us that the Caffeine has more polarity than other compounds because it stays in stationary phase which has high polarity. In contrast‚ the Ibuprofen is less polar‚ because it travels with the solvent which is less polar also. Therefore‚

purpose of this experiment is to determine the components of an unknown drug and identify it as one of six (6) commercial drugs by using thin-layer chromatography. I added approximately a quarter of a tablet of acetaminophen‚ aspirin‚ caffeine‚ ibuprofen‚ salicylamide‚ and the unknown (#19) to separate test tubes containing 2.5mL of dichloromethane. I noticed that my unknown was a coated tablet. Each test tube was swirled until the greatest amount of each solid was dissolved. Each solution was spotted

She was not evaluated by a rheumatologist. Despite scheduled APAP and ibuprofen throughout the day‚ the pain has not decreased much. The pain seems to be cyclical; it is very bad for a period of weeks‚ and then it wanes over time. It is also worse in the summer. She thinks the rashes she gets now and then on her face and arms
