Information and Research 1. Paper chromatography is used to break down colors with using water and the way the colors separate. 2. Doctors can use it to test for alcohol in people’s blood. People can also use it to check for pollutants in the water. Pharmacists can use it to find out how much of each chemical is in each product. 3. I searched it up on google. Purpose The purpose of this test is to see what colors are in certain colors. We use chromatography to separate them/ Materials

Section 1 Purpose: The purpose of this lab was to separate plant pigments using chromatography‚ calculate Rf values using the collected data‚ and study photosynthesis with isolated chloroplasts. Light energy Light energy Background Information (Activity A): In photosynthesis‚ plant cells convert light energy into chemical energy that is stored in sugars and other organic compounds. It is an endergonic and anaerobic reaction. Critical to the process is chlorophyll‚ the primary photosynthetic pigment

was measured Predictions: Chlorophyll a absorbs best at a wavelength of 400‚ Chlorophyll b at 450‚ carotene at 500‚ and xanthophyll at 450. Materials & Methods: Experiment: First all the materials were gathered. Pigments were separated by chromatography paper. Pigments were loaded in a line on the paper. The paper was folded in a cylinder‚ stapled‚ placed in a cylinder with solvent‚ and sealed with wax paper until the pigments separated. After the pigments separated the paper was taken out to

Immunoprecipitation is based on a similar principle as: a) b) c) d) e) SDS-PAGE Ion exchange chromatography Size exclusion chromatography Affinity chromatography PCR 3. How is a Western blot different from a Southern Blot‚ as we covered in class? a) b) c) d) e) f) A Western blot uses a gel. A Western blot uses a membrane. A Western blot uses an antibody. A Western blot uses

The concentration of residual chlorite ion in vegetables and eggs treated with sodium chlorite was determined by UV-ion chromatography (Suzuki et al. 1997). Sodium chlorite was extracted with water and cleaned-up using C18 cartridge. The detection

Today in lab I will separate mixtures of compounds into their constituent components using chromatography paper and an eluting solvent of salt water as well as rubbing alcohol. Materials and Methods: In this lab using the bag of FD&C dyes‚ bag of M&M’s‚ 2 packs of Kool-Aid ‚ and a pack of Clover Valley store brand food coloring I am going to place a drop of each dye at the bottom of the chromatography paper. For the experiment with the rubbing alcohol I also placed a drop of each dye‚ but used
