Title Identification of Analgesic Compounds Using Thin Layer Chromatography Abstract The objective of laboratory experiment six was to identify an unknown analgesic tablet using Thin Layer Chromatography (TLC) analysis. The procedure involved preparing TLC plates‚ solubilizing standard analgesics (ibuprofen‚ aspirin‚ acetaminophen‚ caffeine) and the unknown in isopropyl alcohol (IPA)‚ and developing the plates in acetone. Rf values were calculated for each compound. The unknown tablet showed an Rf

Alkaline Phosphatase was isolated using various techniques. BCIP spot test was performed after the anion exchange chromatography was done and the fractions were collected. The picture of BCIP spot test of the 20 fractions can be seen in figure 1. The intensity of each spot was different from each other. The more intense color the spot was‚ the more concentrate the AP was. The fractions were chosen to combine together based on the intensity‚ which made the stage 4 enzyme. Different volumes in each

Abstract Pigments extracted from different greens have different polarities and may be different colors. Mixed pigments can be separated using chromatography paper. Chromatography paper is able to separate mixed pigments due to their polarity and solubility. Pigments of chlorophyll a‚ chlorophyll b and beta carotene will be separated on chromatography paper because each has its own polarity and solubility‚ which results in different distance traveled up the paper. Beta carotene is non-polar so it
