exchange Chromatography Ion exchange chromatography is a process for separating proteins and other molecules in a solution based on differences in net charge. Ion Exchange Chromatography relies on charge-charge interactions between the proteins in your sample and the charges immobilized on the resin of your choice. Ion exchange chromatography can be subdivided into cation exchange chromatography‚ in which positively charged ions bind to a negatively charged resin; and anion exchange chromatography‚ in

In phase one of the trial‚ Sharma et al. (2000) attempted to find a stabilized dosage of duloxetine the would be appropriate. This trial consisted of 12 men‚ between ages 22 to 53 years old‚ weighing between 61.7 to 88.9 kilograms‚ and they were also roughly around 160 to 188 centimeters tall. While these men were participating in this study‚ they were not allowed to take in any medication other than what was being studied. Before the patients started this trial they all had to provide a written

Chromatographic conditions Shimadzu VP-ODS column is (250 mm x 4.6 mm i.d.‚ 5 µm particle size)‚ Shimadzu‚ Kyoto‚ Japan. The mobile phase consisted of a mixture of 0.3% TEA‚ 10% n-propanol in a solution of 0.1 M SDS adjusted to pH 2.8 using 0.02 M orthophosphoric acid. It was pumped at a flow rate of 1 mL min-1. The column was kept at ambient temperature and the wavelength of the detector was at 225 nm. Standard solutions Stock solutions of LVD‚ CBD and ETC containing to 1.0 mg mL-1 were prepared

Plant Pigment Chromatography VII. Analysis (Questions) 1. What factors are involved in the separation of pigments? Factors that are involved in the separation of pigments can include pigment solubility‚ the attraction between the pigments and paper and the size of each pigment particle. Because of these factors the results were as they were. Beta-carotene traveled the furthest because it forms no hydrogen bonds to the chromatography paper and is slightly soluble in the solvent. Contrastingly

Data and Conclusions: The purpose of this experiment was to learn how to use distillation and gas chromatography to separate and identify different compounds from a given mixture. There are several kinds of distillation methods. However‚ the method that we used in this experiment was fractional distillation. This method is used when trying to separate two different volatile compounds whose boiling points differ by 40-50°C or more. If the boiling points are too close‚ this method

EXPERIMENT 4 ANALYSIS OF HYDROCARBON IN COMMON FUELS BY SOLID-PHASE MICROEXTRACTION (SPME) AND GAS CHROMATOGRAPHY-MASS SPECTROMETRY (GC-MS) Abstract In the analysis the solid-phase microextraction (SPME) and capillary gas chromatography/mass spectrometry (GC/MS) was developed for the identification of volatile compounds (hydrocarbon) in fuel. The samples was used is (kerosene‚ diesel‚ thinner and petrol) and one unknown. After the analyte was extracted by SPME in 20min‚ it directly injected

Gas chromatography (GC) is a chromatography technique where the separation of individual components (analytes) from a sample relies on their differing distribution between a mobile and stationary phase. The mobile phase carries the analytes through the stationary phase. In GC‚ it’s an inert gas (usually helium or nitrogen). The gas must be inert‚ so it won’t react with the sample to give a false reading. The stationary phase is a substance fixed in place to which the sample adsorbs because
