- How do I determine which calibration solution to use with each Thermo Fisher Scientific mass spectrometry instrument?
- Can I use Thermo Fisher Scientific calibration solutions with non-Thermo Fisher Scientific mass spectrometry instruments?
- Are mass spectrometry calibration solutions stable at room temperature? Can I store them in other containers?
- Which standard do you recommend using for Tandem Mass Tag (TMT) workflows?
- I don’t need a complex digest for my MALDI study, but I need something more than a single protein digest. What do you recommend?
- I have a low number of protein identifications from my protein digest sample. What can I do?
- I observe peptide retention time shifts in my liquid chromatography (LC) chromatogram. Do you have a standard I can use to check my LC performance?
- A database search of my peptide samples shows low and/or no identifications, but I have excellent signal in my chromatograph. What might be the problem?
- My spray stability is erratic in my mass spectrometer, can you help?
- I’m struggling with mass spectrometry sample clean-up and feel that I’m losing peptides. Can you help me verify?
