Interpretation:
The reason why thermal conductivity detector responses to all analyte except carrier gas and why flame ionization detector isn’t universal has to be explained.
Concept Introduction:
Gas chromatography detector:
Flame ionization detector and thermal conductivity detector are most commonly used detector in gas chromatography. They both are sensitive to wide range of components and work over wide range of concentrations. Thermal conductivity detector is used to detect any component other than carrier gas whereas Flame ionization detector is sensitive to Hydrocarbons and is more sensitive than Thermal conductivity detector. Water cannot be detected by Flame ionization detector. Thermal conductivity detector is non-destructive and could be operated in series but Flame ionization detector is destructive one.
Some other detector includes catalytic combustion detector, discharge ionization detector, Electron capture detector, Flame photometric detector etc.
To explain why thermal conductivity detector responses to all analyte except carrier gas and why flame ionization detector isn’t universal

- Phenol is the starting material for the synthesis of 2,3,4,5,6-pentachlorophenol, known al-ternatively as pentachlorophenol, or more simply as penta. At one time, penta was widely used as a wood preservative for decks, siding, and outdoor wood furniture.
