Question
a) In any gas chromatographic analysis, exceeding a column's maximum temperature limit will usually result in column bleeding. i) Define what is column bleeding. Give another approach other than reducing column final temperature to prevent ii) column bleeding. b) Flame ionization detector (FID), electron capture detector (ECD) and mass spectrometry detector (MSD) are widely used with gas chromatographic separations. i) Explain why FID is sensitive to organic compounds but insensitive to noncombustible gases such as CO2, SO2, CO and NO. ii) State the type of compounds that responds to ECD and MSD.
