2. Chromatography is an analytical technique that is widely used for the separation, identification and determination of the chemical components in complex mixtures. It is a very powerful method of separation. Describe how the separation of mixture is done using a. thin layer chromatography. b. Column chromatography
1) List the desired characteristic of an HPLC detector {4} 11) Briefly, but informatively, describe the following columns in liquid chromatography, a Guard column b Scavenger column {4} One of the recent developments in liquid chromatography is in column chemistry. Le hydrophilic interaction liquid chromatography (HILIC) Briefly, but informatively, discuss the importance of this development
A UV-VIS detector is used for the liquid chromatography section of LCMS. q. What B Group vitamins would not show up? (not be detcted, or thought not to be detected)
Lab #2: Gas Chromatography Theory behind gas chromatography What do all types of chromatography share in common? Relationship between retention time and boiling point/vapor pressure How changing parameters affect the retention time Ramp rate Temperature Length of column Pressure Whether column is packed or unpacked
