Experiment 5 Analysis of Plant Pigment Purpose: Chromatography is used for separation. In this case the separation of plant pigments. After placing the plant sample in the column the separation will be easy to see and the samples will be analyzed using VIS spectrophotometry. This is used to isolate and identify the different lipids causing the different pigmentations. Introduction: Lipids are chemically diverse substances found in cells. Lipids are water-insoluble‚ structural components

The purpose of this experiment was to identify amino acids in a mixture through cation exchange chromatography and thin layer chromatography. This was done by examining the amino acids elution order from a cation exchange resin based on their isoelectric points and their different

Extract DNA from Anything Living |[pic] | |Introduction: [pic] Since DNA is the blueprint for life‚ everything living contains DNA. DNA isolation is one of the most basic and essential techniques in the study of DNA. The extraction of DNA from cells and its purification are of primary importance to the field of biotechnology and forensics. Extraction and purification of DNA are the first steps in the analysis and manipulation of DNA that allow scientists to detect genetic disorders‚ produce DNA

You could always add or take out ingredients according to your taste. I always have rice‚ sesame oil and soy sauce at home so I skipped the three items. I grabbed a shopping cart and walked to the right hand side to the fresh produce department. I picked up some Asian spinach and scallions. Asian spinach is similar to baby spinach used in salad‚ but

A very thin (micron) film of silica is coated on a glass plate or a sheet of aluminum or plastic. The ingredients of commercial analgesics were characterized in comparison with chromatograms of aspirin‚ Acetaminophen‚ caffeine and mefenamic

objective of the lab is to separate the caffeine samples we are using‚ using thin layer chromatography. The solvent we are using for the separation is 3:1 mixture of Chloroform and Acetone. Principle: Thin layer chromatography (TLC) is an important technique that is useful for separating organic compounds. TLC is often used to monitor the progress of organic reactions and to check the purity of products. Separations in Thin layer chromatography involve distributing a mixture of two or more substances

There are four main types of chromatography; these are Liquid Chromatography‚ Gas Chromatography‚ Thin-Layer Chromatography and Paper Chromatography. Chromatography is used extensively in forensics‚ from analyzing body fluids for the presence of illicit drugs‚ to fiber analysis‚ blood analysis from a crime scene‚ and at airports to detect residue from explosives

This analytical process‚ despite having been replaced by the success of thin layer chromatography‚ still stands as a valuable teaching tool‚ and is nevertheless very common. This method is very useful because not only is it a relatively quick process‚ but also requires only small quantities of materials. The substances being
