GCConfiguration
TheFID/methanizer detects all
hydrocarbons frommethane to
hexane and alsoCO andCO2
which are converted tome-
thaneby themethanizer.
Detection from 1ppm to
50,000ppm are possible.
Shown aremethane, CO and
CO2 at 1000ppm.
TheTCD detectsHydrogen,
Oxygen, Nitrogen,Methane,
CO, CO2,Water and all mol-
culeswith boiling points below
hexane. Detection of most
molecules is possible from
500ppm to 100%. Hydrogen
can be detected from 10ppm to
100% if usingNitrogen or Ar-
gon carrier, but this increases
detection limits for everything else
from 500ppm to about 5000ppm.
With helium carrier detection limit for
hydrogen is about 10,000ppm to
100%.
In some cases, theGC can be
equippedwith a secondTCD detec-
tor , valve and column specifically to
detect Hydrogenwhile helium carrier
is used for the othermolecules.
