which combined all three sources and represented them as the dependence of the theoretical plate height (HETP) on the mobile phase linear velocity. Originally‚ it was introduced for gas chromatography‚ but it happened that the same physical processes occurs in HPLC‚ and this equation is perfectly fit for liquid chromatography. Multiple path The velocity of mobile phase in the column may vary significantly across the column diameter‚ depending on the particle shape‚ porosity‚ and the whole bed structure

In this article I will explain whether I think gas prices will stay low. I have gathered some information and details to support my opinion. I will back up every detail that I think about whether gas prices should stay low. In the end I will have done explained why I think gas prices should stay low or not with some information to support it. I think that gas prices will not stay low. I think that gas prices will not stay low because their are alot of people who are taken advantages of it. People

Procedure: 1) Set up all the apparatus 2) Open the rubber cap. Move the closed tube several times to ensure that the oil is spread equally. 3) Pour boiling water into the beaker and put thermometer into beaker. 1.

CHE 213-451 11-1-11 Title: Radical Chlorination of 1-Chlorobutane Abstract: The purpose of the lab is to form 4 different dichlorobutanes by reacting chlorine radicals with 1-chlorobutane. This is then analyzed by gas chromatography to determine the experimental abundance of each isomer. Results: 1‚1-dichlorobutane had an experimental abundance of 5.9%‚ 1‚2-dichlorobutane had an experimental abundance of 21.1%‚ 1‚3-dichlorobutane had an experimental abundance of 48.7%‚ 1‚4-dichlorobutane

Title: Liquid Chromatography Author: Gloria Contreras Lab Partner: Jose Montanez Instructor: Teresa Potter Date Work Performed: January 13‚ 2015 Date Submitted: January 20‚ 2015 Abstract: In this lab‚ liquid chromatography is used to separate the Red 40 and Blue 1 dyes inside of grape flavored Kool-Aid. It was determined that the 5% isopropanol will remove the Red 40 dye from the stationary phase. The 28% isopropanol will remove the Blue 1 dye from the stationary phase. The more

Ideal Gas Law Lab 1. Procedure: First‚ we used a balance to weigh the canister of gas‚ and recorded that mass as the original weight. Then‚ we filled a large bucket with water and recorded the temperature. We then filled a small test tube with water at the same temperature and poured that water into a graduated cylinder to measure the original volume of water in the tube. We then poured the water back into the test tube and placed the tube into the bucket with the opening upwards‚ turning the

Gas Law Problems Boyles Law 1. A gas occupies 12.3 litres at a pressure of 40.0 mm Hg. What is the volume when the pressure is increased to 60.0 mm Hg? 2. If a gas at 25.0 °C occupies 3.60 litres at a pressure of 1.00 atm‚ what will be its volume at a pressure of 2.50 atm? 3. To what pressure must a gas be compressed in order to get into a 3.00 cubic foot tank the entire weight of a gas that occupies 400.0 cu. ft. at standard pressure? 4.
