The ozone layer diminishes more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger‚ additional ultraviolet rays are allowed to pass through. These rays cause cancer‚ cataracts‚ and lowered immunity to diseases.1 What causes the depletion of the ozone layer? In 1970‚ Crutzen first showed that nitrogen oxides produced by decaying nitrous oxide from soil-borne microbes react catalytically with ozone hastening its depletion. His findings started

Gas Chromatography Analysis of Product Mixtures Gas Chromatography Guidelines‚ Handout. Introduction Gas chromatography is a technique used to analyze chemical compounds that can be vaporized and separated in a gas phase column. Once separated‚ the analyzed substance is passed through a detector and data is obtained. The samples that we are going to analyze are: the EtOAc from Simple distillation‚ the Fraction 1‚ Fraction 2‚ and Fraction 3 from the Fractional Distillation. Experimental Procedure

CHEM 3152-003 Experiment 2: Fractional Distillation and Gas Chromatography Introduction: The purpose of this experiment was to separate a mixture of ethyl acetate (EtOAc) and toluene by using the method of fractional distillation and to analyze the fractions using gas chromatography (GC). ethyl acetate toluene Distillation is a method known as separating or purifying a liquid or mixture by vaporization and condensation. In a simple distillation‚ the liquids being separated boil below 150 0C

Candy Chromatography: What makes those colors? The point of doing this project is to use paper chromatography to see which dyes are used in the coatings of your favorite colored candies. Chromatography is a technique for separating mixtures. Chromatography can be used to separate specific components from a complex mixture‚ based on molecular size or other chemical properties. It can also be used to identify chemicals‚ for example crime scene samples like blood‚ drugs‚ or explosive residue. Highly

Chromatography Experiment of the Drosophila Eye Pigmentation Pathway Introduction: How can the use of chromatography help explain single gene mutations of the drosophila melanogaster bio-synthetic pigment pathway? This experiment was meant to help connect the mode of inheritance with different eye color mutations and pinpoint where they occur in the pigment pathway. The drosophila eye color is a result of two bio-synthetic eye color pathways‚ this is expressed as a trait or phenotype‚ a multigene
