compound with high reproducibility. The materials for constructing a HPLC column are inert to the analytes such as polished stainless steel, glass and PEEK polymers. There are mainly four types of columns used in HPLC which are high performance analytical column, preparation column, capillary column and…

like molecular weight, density, shape, etc. If it is used for the separation of one type of materials from others is termed as preparative centrifugation and when used for measurement of physical properties of macromolecules, then it is known as analytical centrifugation. Principle of centrifugation: Particles suspended in a solution are pulled downwards by Earth’s gravitational force. In a solution, particles with higher mass…

1. It is necessary to list the experimental conditions when reporting a chromatogram because it will allow universal comparison. In the event that you want to compare your results with a colleague, the factors that can affect the results are listed and taken into consideration to get an accurate comparison. 2. The type of column used is listed, this column contains the stationary phase and the mobile phase is pumped through the column under pressure. The dimensions of the column are listed as…

Chromatography is a method of separation in which the components of a substance are separated and distributed between two phases, which are the mobile phases and stationary phase (1). There are multiple types of chromatograph, which includes paper chromatography, column chromatograph, retention chromatography, gas chromatography, liquid chromatography etc. Each technique has its own strengths and weaknesses, but all are useful in getting separations of different components (8). Since many…

High Performance Liquid Chromatography Lab Abstract High performance liquid chromatography or HPLC is the process in which mixtures are physically separated according to their polarity. The lab conducted, the separation of dyes in grape Kool-Aid, demonstrated the concept. This was done to display how different alcohols and their concentrations have different polarities, in which ties into HPLC. The lab consists of testing Kool-Aid, water, and different concentrations of methanol and…

1833, Ada met the brilliant mathematician named Charles Babbage who she became lifelong friends with, Ada was overly intrigued with his idea about a “Analytical Engine” it was a mechanical calculating machine that it’s design predated the digital computer by over 100 years. In 1842, mathematician Louis Menebrea published a memoir explaining the “Analytical Engine” which it would be translated from French to English by Ada for Babbage., In Ada’s notes she had described how the codes could be…

Paper Chromatography Paper Chromatography is an analytical method that is used to separate coloured chemicals substances, especially pigments. This is how paper chromatography is conducted: Materials Chromatography Paper (Can also be Coffee Filter) Large Beaker (max one litre) Paper Clips/Sellotape & Skewer Stick Water soluble black marker Water Procedure: Draw a ink dot with the marker on each one of the chromatography paper near the bottom end of the paper. Then stick or paper clip the…

The objectives of this lab where to determine the empirical formula of a hydrated copper (ll) sulfate sample, practice writing detailed observations in the laboratory and practice calculating mass percent composition. Before beginning taking measurements, read through the instructions below and make a neat table in which to record all the numerical data. Using tongs put a clean crucible on the hotplate. Heat the crucible for approximately 5 minutes. Turn off the hotplate. Carefully remove the…

Introduction The use of drugs of abuse has become an increasing problem throughout the world. Drugs of abuse range from anything to illegal drugs such as cocaine, misuse of prescriptions or even nicotine. Drugs of abuse are more than just harmful to a person’s health, they also have an impact the environment, including water treatment processes. The purpose of these experiments is to identify the compounds in aquatic samples from various places throughout the world. Verifying these compounds is…
