Consider the following statements as they apply to gas chromatography. Decide if each is true or false. 1. ___ Temperature programming is necessary only for samples containing compounds with a narrow range of boiling points. 2. ___ GC carrier gases are generally inert gases like helium and nitrogen. 3. ___ The injection port temperature should be set at the average boiling point of all analytes. 4. ___ An FID is a mass-sensitive detector, not a concentration-sensitive device. 5. ___ An air peak is commonly used to determine the dead time when using an FID detector.
