Plant Pigment Chromatography VII. Analysis (Questions) 1. What factors are involved in the separation of pigments? Factors that are involved in the separation of pigments can include pigment solubility‚ the attraction between the pigments and paper and the size of each pigment particle. Because of these factors the results were as they were. Beta-carotene traveled the furthest because it forms no hydrogen bonds to the chromatography paper and is slightly soluble in the solvent. Contrastingly

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

The goal of this lab was to create and purify DHFR from BL21 ecoli using column chromatography. To know if we isolate DHFR their will be one band at 53 KD or above 50 KD and in our desalted eluate page should have the highestOD₂₈₀ which translates to the highest enzyme activity .Column chromatography is a method used to purify individual chemical compounds from mixtures of compounds. The main advantage of column chromatography is the relatively low-cost and disposability of the stationary phase used

Experiment 5 Analysis of Analgesic Tablet by High Performance Liquid Chromatography Abstract An unknown sample‚ 529‚ was tested using high performance liquid chromatography to detect the concentrations of acetaminophen‚ aspirin‚ and caffeine respectively. There was found to be 4.03±0.144mg/100mL of acetaminophen‚ 11.5±0.185mg/100mL of aspirin‚ and 4.89±0.185mg/100mL of caffeine. Based on accepted values‚ the maximum daily amounts of each compound are 4000mg of acetaminophen

Data and Conclusions: The purpose of this experiment was to learn how to use distillation and gas chromatography to separate and identify different compounds from a given mixture. There are several kinds of distillation methods. However‚ the method that we used in this experiment was fractional distillation. This method is used when trying to separate two different volatile compounds whose boiling points differ by 40-50°C or more. If the boiling points are too close‚ this method

Briefing Thin-layer chromatography (TLC) is an extremely valuable analytical technique. It provides a rapid separation of compounds‚ and gives an indication of the number and nature of the components of a mixture. TLC can also be used to identify compounds by comparison with known samples‚ to check the purity of a compound‚ or to monitor the progress of a reaction‚ an extraction‚ or a purification procedure. This experiment will introduce you to the mechanics of TLC‚ and the chemical principles

Spinach E6 - Investigation of the Photochemistry of Chlorophyll The aim of this experiment is to investigate the photochemistry of chlorophyll. This experiment will be performed in two lab periods. In the first lab period you will extract chlorophyll‚ the green pigment in leaves‚ from spinach. In the second lab period you will investigate the interaction of light with chlorophyll. Read in Appendix B the reference section titled "Electronic Structure of Matter" copied from reference 1 before performing
