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

possible to identify which peak correlates with which compound. Figure 2 contains a peak at around 500 and 700 nm which is a good indicator that that would-be chlorophyll b. This makes sense because this was the bottom band from the thin layer chromatography and chlorophyll b is the most polar compound. Chlorophyll B contains an aldehyde where chlorophyll A has a methyl group making it slightly more polar. Following that‚ figure 4 contains

Gas chromatography is the common method used for the biogasoline analysis. Biogasoline catalytic cracking process requires detailed qualitative and quantitative analysis of the hydrocarbon composition of its oil and fraction. In this analysis‚ their fractional composition‚ saturated vapor pressure‚ density and antiknock rating will be investigated. By knowing the qualitative and quantitative composition of the gasolines‚ the content of n-paraffin‚ isoparaffin‚ aromatic‚ naphthene‚ and olefin (PIANO)

BRAND: HISTORY: The Band-Aid was invented in 1920 by Earle Dickson‚ an employee of Johnson & Johnson‚ for his wife Josephine Dickson‚ who frequently cut and burned herself while cooking. The prototype product allowed his wife to dress her wounds without assistance. Dickson‚ a Highland Park‚ New Jersey resident at the time‚ passed the idea on to his employer who then went on to produce and market the product as the Band-Aid. Dickson had a successful career at Johnson & Johnson‚ eventually
