Which of the following is NOT a common type of gas chromatography?

Which of the following is NOT a common type of gas chromatography?

Step 1: Understand what gas chromatography is. It is a method used to separate and analyze compounds that can be vaporized without decomposition.
Step 2: Identify common types of gas chromatography. These include methods like capillary gas chromatography and packed column gas chromatography.
Step 3: Look at the options given in the question. One of the options is supercritical fluid chromatography.
Step 4: Recognize that supercritical fluid chromatography uses supercritical fluids (not gases) as the mobile phase.
Step 5: Conclude that since supercritical fluid chromatography does not use gas as the mobile phase, it is NOT a type of gas chromatography.
