Experiment #1: Thin-Layer Chromatographic Analysis of Drug 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

In his book‚ Into Thin Air‚ Krakauer describes climbing to the summit of Mount Everest as a ’breathtaking experience’. The thinning of oxygen is just one of the many perilous events that unfolds while the climbing of this monster of a mountain. There are illnesses that one can get while descending too high too quickly‚ and limbs to be lost to the freezing cold. Worse‚ one could inevitably come to their own death by falling into a crevasse or for loss of air supply. There is no doubt that climbing

At some point in everyone’s life they come across a life changing obstacle‚ also known as their everest. In the book‚ Into Thin Air by Jon Krakauer‚ the climbers Jon Krakauer‚ Rob Hall‚ sherpas‚ and many other people‚ climb Mount Everest with hopes of summiting. For them this is their everest. When the word everest is said the automatic thought is Mount Everest‚ but in this case everest holds the definition of a tough obstacle that is overcome because of the work and effort that was put into it to

The former climber and now journalist is sent on mission that would change his life. Team members die‚ storms hit‚ oxygen is low‚ will they survive?

Jon Krakauer wrote Into Thin Air‚ which was also featured as an article in the Outside magazine. It was based on his own experiences and observations of the time he attempted and completed the climb of Mount Everest in 1996. Krakauer wanted to share and let everyone know of the whole expedition because he felt it was necessary. The feedback he received from readers was extremely high and it was all positive and negative opinions. The negative feedback was what made Krakauer disturbed‚ but he did

Thin-Layer Chromatography of Analgesics Abstract: In this experiment thin-layer chromatography (TLC) was used to determine the composition of an unknown mixture of analgesics given five references of AC‚ ASP‚ CAF‚ IBU‚ SAL‚ an unknown consisting of a mixture of three of the references‚ and two unknowns (6‚23) containing a single reference compound. The composition of the unknown mixture and two single unknowns were determined by spotting the reference compounds and the unknown compounds on two
