Questions & Step-by-Step Solutions
What is the main advantage of using gas chromatography over liquid chromatography?
Step 1: Understand what gas chromatography (GC) is. It is a method that uses gas to separate and analyze compounds.
Step 2: Understand what liquid chromatography (LC) is. It is a method that uses liquid to separate and analyze compounds.
Step 3: Identify the types of compounds each method is best for. GC is best for volatile compounds (those that can easily become gas), while LC is better for non-volatile compounds.
Step 4: Recognize that sensitivity means how well a method can detect small amounts of a substance.
Step 5: Realize that GC can detect smaller amounts of volatile compounds than LC can detect non-volatile compounds.
Step 6: Conclude that the main advantage of GC over LC is its higher sensitivity for volatile compounds.
