- 1) When you try separating an unknown mixture by normal-phase liquid chromatography with 50% hexane and 50% methyl t-butyl ether, the peaks are too close together. (not resolved) Should you use a higher or lower concentration of hexane in the next run?what are key reactions involved in seperation of liquid mixtures by simple and fractional distillation and gas chromatography? chemicals used: 10ml 1:1 mixture of ethyl and butyl acetate techniques: simple and fractional distillation, gas chromatography. target molecules: Ethyl acetate C4H8O2 Butyl acetate C6H12O2Suppose that you try separating an unknown mixture by normal-phase chromatography with the solvent mixture 50% hexane-50% methyl t-butyl ether (which is more polar than hexane). The peaks are too close together and are eluted rapidly. Should you use a higher or lower percentage of hexane in the next run?
- Why do H2 and He allow more rapid linear flow rates in gas chromatography than does N2, without loss of column efficiencyConsider the following statements as they apply to gas chromatography. Decide if each is true or false. 1. ___ Temperature programming is necessary only for samples containing compounds with a narrow range of boiling points. 2. ___ GC carrier gases are generally inert gases like helium and nitrogen. 3. ___ The injection port temperature should be set at the average boiling point of all analytes. 4. ___ An FID is a mass-sensitive detector, not a concentration-sensitive device. 5. ___ An air peak is commonly used to determine the dead time when using an FID detector.Why ebuilliometer is having a great effect on measuring ethanol Yield than gas chromatography
