Default presentation of MALDI MS data



Dear all,

I am very new person in area of mass spectrometry. I have collected some MALDI-TOF-MS (voyager DE STR) data. What is the exact way to represent MALDI MS spectra? should I represent spectra with absolute intensities or relative intensities? also If I am comparing two different spectra of same analyte which one is better: absolute intensity or relative intensity?

ajeet.

Default Re: presentation of MALDI MS data

Generally you present as relative intensities, otherwise you have to specify exactly WHY you used relative intensities. Relative intensities also allow you to compare data across different instruments.
