Chromatography refers to a set of laboratory methods used in separating as well as purifying biomolecules. A variety of chromatography techniques exist‚ and all depend on the interaction between a stationary and a mobile state. Two types of chromatography methods were examined in this investigation. First‚ ion-exchange chromatography was used. This method separates ions and polar molecules based on their affinity to the ion exchanger [2]. Specifically‚ cation-exchange chromatography was performed

Develop a Country with AIDS One often hears that the drug is a ladder to be a developed country. When every illness has its own cure‚ there will be no health problems that we have to consider. Therefore‚ everyone can work hard‚ achieve his or her own success‚ and juxtapose the welfare of the country. But‚ is it true that drug will only bring favorable effects to the society? Is it true that drug is the heavenly way to achieve prosperity? When we talk about drugs‚ we cannot ignore one of the deadliest

Performance Liquid Chromatography (HPLC) Instructor: Dr. Hüseyin BOZKURT High Performance Liquid Chromatography (HPLC) is one mode of chromatography‚ the most widely used analytical technique. Chromatographic processes can be defined as separation techniques involving mass-transfer between stationary and mobile phases. Present day liquid chromatography that generally utilizes very small packing particles and a relatively high pressure is referred to as high performance liquid chromatography (HPLC).

Separation of Amino Acids by Cation Exchange Chromatography Introduction and Purpose: Amino acids are small biomolecules that have a carboxylic acid backbone in common‚ as well as an amino group attached to a saturated carbon. There are many amino acids‚ but there are 20 most commonly know amino acids. Amino acids are the fundamenta building blocks of other biomolecules like proteins and ezymes (Davidson‚ 2015). This experiment examined a mixture of 3 amino acids. The purpose of this experiment

Question 1 1.1 Silica gel chromatography: This is known as the stationary phase in column chromatography. Firstly‚ the tapered exit of the column is sealed using porous material. This porous material serves as support for the packing material‚ and prevents it from exiting the pipe. Thereafter‚ silica gel is compacted into the glass pipe to make the separating column. In finishing preparation of the column‚ the solvent which is used as the mobile phase is then passed through the dry column. Then the
