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

Separation techniques LIQUID CHROMATOGRAPHY ‘THE ART OF SEPARATION’ CHROMATOGRAPHY – AN INTRODUCTION Chromatography is a technique through which a mixture of chemical components are separated‚ identified and determined accurately. This technique while provides a way for analytical separations‚ also useful for preparative techniques by which pure compounds can be obtained.

Hope is a feeling that keeps a person going. Hope is belief in an optimistic result that is related to different events and situations that occur in a person’s life. Hope implies a certain amount of determination. A person is determined when he or she believes that the outcome of an event will be positive even when the facts that are laid out are negative. This form of hope can be seen through famous people who used hope to overcome their struggles Lance Armstrong was diagnosed with serious cancer

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).

LeGuin‚ “The Washwoman” by Isaac Singer‚ and “The Last Leaf” by O. Henry‚ the theme of loss is illustrated through the loss of a family member‚ prized possession‚ and a friend. Any heirloom passed down through a family gains personal value with each consecutive generation‚ and Gwilan’s harp is no exception

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
