Mass Spectrometry Standards and Calibrants Support
Explore our “Getting Started” and “Troubleshooting” sections for solutions to top inquiries and common problems. Browse through our "Guides and Tools" section to access a comprehensive portfolio of product-related support resources.
Getting Started
- 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?
Troubleshooting
- 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?

Custom Services
Custom Peptide Synthesis Services
Thermo Scientific Custom Peptide synthesis service offers numerous options for synthesis platforms, purity levels, modifications, and formats to meet a variety of research needs. We synthesize peptides of 2–110 amino acids using the latest FMOC solid-phase technology, and purify our products using HPLC. Synthesis scales range from 0.1 mg to 1 g, and purities from crude to >98% based on the service.
HeavyPeptide AQUA Custom Synthesis Service
Thermo Scientific HeavyPeptide AQUA Custom Synthesis Service provides isotopically labeled, AQUA-grade peptides for the relative and absolute quantitation of proteins at very low concentrations in complex protein mixtures. Peptides are synthesized using the latest FMOC solid-phase technology and purified by HPLC. All HeavyPeptide sequences come with mass spectrometric analysis and analytical HPLC dat. Additionally, we offer a wide range of labels, modifications, scales, and purities.
