What are the differences and advantages of UPLC over HPLC?An example of planar chromatography is: Column chromatography HPLC GLC TLCQno1: why there is a need of chromatography and chromatography thecniqs. B) when and where we should use normal and reverse phase chromatography
- Gas Chromatography (GC) is one of the useful techniques in analytical chemistry. Give two important components in GC.UV-Vis Absorption is a type of data base system injector detector pump Gas chromatography is one of the following types O paper chromatography thin layer chromatography (TLC) column liquid chromatography None of the aboveWhich is correct? Random errors affect accuracy and systematic errors affect precision. An accurate result shows agreement with the true or accepted value. Precise results can contain significant random error, but little systematic error. The standard deviation is a good measure of accuracy. Polydimethylsiloxane (PDMS) stationary phases have low polarities. Which of the following statements is TRUE about gas chromatography using PDMS stationary phases? The gas chromatography column is typically packed with silica microparticles. An oven is used to control the column temperature because a constant temperature is always needed in gas chromatography Octane (C8H18, boiling point: 126 ºC) is eluted later than dodecane (C12H26, boiling point: 216 ºC) 3-Pentanone ((C2H5)2CO, boiling point: 102 ºC) is eluted later than propanol (CH3CH2CH2OH, boiling point: 97 ºC)
