GC is commonly used for
quality control as well as identification and quantitation of compounds in mixture
mobile phase
gas
stationary phase
a high-boiling liquid on a solid support
how does GC work
the separation of compounds us based on the different strengths of interaction of the compounds with the stationary phase
the stronger the interaction is,
the longer the compound interacts with the stationary phase, and the more time it takes to migrate through the column
retention time
time for the compound to pass through the column
peak area
proportional to the amount of material
drying agents -
removes traces of water
most drying agents are
anhydrous (water free) inorganic salts that form hydrates by combining chemically with water
