Explain what are the differences between "SCAN" and "SIM" in GC-MS. Why is "SIM" needed to achieve high sensitivity and lower detection limit?
Added by James P.
Step 1
In GC-MS, the sample is first separated by gas chromatography, and then the separated components are ionized and analyzed by mass spectrometry. There are two modes of operation in GC-MS: Scan mode and Selected Ion Monitoring (SIM) mode. Scan mode is a Show more…

There are many types of detectors used with GC and HPLC systems. Describe briefly the difference between a universal detector and a compositionally-sensitive detector. Give one example of a universal detector and one example of a compositionally-sensitive detector used in GC. Describe briefly how the two detectors work; that is, how do they detect solutes eluting from the GC column?
