Gas Chromatography refers to the use of a gas chromotograph (a device in which gas compounds are inserted and separated) to find certain information about compounds inserted into the device. The information collected from the device is inserted into formulas to find even more data about the compounds. For example, the phase ratio of a compound is found by dividing the thickness of the compound's stationary phase by the chromotograph's diameter multiplied by two. The phase ratio is then plugged into other chromotography formulas to discern more information about the compound.

Instructions
-
-
1
Record the diameter of the chromotograph from the chromotograph's specifications. These specifications are located in your chromotograph's manual.
-
2
Record the film thickness of the gas' stationary phase from the chromatograph's recorder.
-
-
3
Multiply the chromotograph's diameter by 2. The product of these numbers is referred to as x.
-
4
Divide the film thickness of the stationary phase by x, which is the chromotograph's diameter multiplied by 2 from the previous step. The product of these numbers is the phase ratio.
