Our lab intends to buy a mass spectrometer and I need a little help. We want to study protein posttranslational modification and protein sequenceing and I don't what kind o mass spectrometer I need for that (MALDI, TOF, etc, etc). All I know is that I nees a liquid chromatography combined with the mass spectrometer.
Could someone give me o little help with this ?
I would like to know exactly what is the difference between these MS systems and what applications are they used for. I found only general information on the internet that helped, but not very much. I would also like to know which brand of MS system is best (perheaps some who has worked with diffrent brands of MS systems could answer this).
