    Hello there !!

    I am very new to the field of mass spectrometry and I am currently wondering about the way the instrument collects data.

    Could you please let me know what exactly a scan in a mass spec instrument is? And, how are the MS and MS/MS modes synchronized?

    I appreciate any help in advance

    Thank you so much!

    Please correct me if I am wrong:

    A scan would consist of the m/z-Intensity values of a specific range of ions entering the detector at a particular point of time.

    So, I guess, to look at the spectrum of a particular molecule, we will have to perform several scans, all depending upon how much time it takes to elute. Am I somewhere near to right?
