Question

GC-MS

What is the nature of 2-dimensional data collection and the meaning of "total ion chromatogram" (TIC). If the quadrupole scans the entire mass range two times every second, how many times did the quadrupole scan through the mass range during the separation for the scanning method. If each takes 1kB of disk space, how much disk space does the multi-dimensional chromatogram occupy? PLEASE HELP, not sure what is being asked
