What is the principle behind the Gas Chromatography?

Answer 1

Gas is pushed threw a filimint gas is broken down into 4 gases and total gas so there is gas c1 c2 c3 c4 and tg or total gas so say 100 units of gas come in to a cromatograph 20 units burn at c1 level that means there is 20 units of c1 c2 level 30 units of gas burns away. I used to be a mud logger in the oilfields :) the most easy job i ever had 300 dollars a day for doing nothing :)

Answer 2

Gas Chromatography separates compounds based on their affinity for the stationary phase inside a column. As the sample travels through the column, compounds with stronger interactions with the stationary phase will move slower, leading to separation based on their chemical properties. Detection occurs as the separated compounds exit the column.
