Mass Spectrometry
Our goal is to provide expert analytical services to North Carolina State University researchers at a cost-effective rate using state-of-the-art instrumentation.
Core Services
(Fee-for-Service)

Proteomics & Protein Characterization
- Targeted Protein Identification: Available for samples in-solution or via in-gel digestion.
- Intact Protein Mass Analysis: Verification of recombinant proteins, synthetic peptides, and antibodies. Ideal for confirming molecular weight, assessing purity, and identifying large-scale modifications.
- Interactome Analysis (Pull-downs): Identification of binding partners from AP/MS (Affinity Purification) or Co-IP assays to elucidate protein-protein networks.
- Comparative Quantitative Proteomics: By digesting proteins into peptides and measuring their relative signal intensities through LC-MS/MS, researchers can quantify and compare the abundance of thousands of proteins across two samples to identify significant biological shifts.
Targeted Metabolomics & Environmental Panels
- Amino Acid Panel: Measurement of relative abundance across standard amino acids.
- Central Carbon Metabolism Panel: Analysis of TCA cycle, glycolysis, and Pentose Phosphate Pathway (PPP) intermediates (relative abundance).
- Environmental Contaminants Panel: Analysis of select pesticides, herbicides, and other pollutants.
- Methyl Salicylate and Related Metabolites Panel: Analysis of methyl salicylate, salicylic acid, salicyluric acid, gentisic acid, salicylic acyl glucuronide, and salicylic phenolic glucuronide in human biological samples (urine and plasma).
- Targeted Ultrashort-chain and Legacy PFAS Panel: High-sensitivity detection of legacy per- and polyfluoroalkyl substances in biological and environmental matrices. Method has been recently updated to also include ultrashort-chain PFAS.

Self-Use Instrumentation

Available Instruments
- HRAM (High-Resolution Accurate Mass): For complex mixture analysis and molecular formula confirmation.
- GC-MS (Gas Chromatography-Mass Spectrometry): Ideal for volatile and semi-volatile compounds.
- MALDI-TOF (Matrix-Assisted Laser Desorption/Ionization): Rapid analysis of polymers, proteins, and synthetic molecules.
- ICP-MS (Inductively Coupled Plasma Mass Spectrometry): High-sensitivity (ppt) elemental and metal analysis .
- QQQ (Triple Quadrupole): Optimized for high-sensitivity targeted absolute quantification using METRIC-validated workflows.
Collaborative Projects

We offer untargeted and targeted collaborative support in:
- Global Proteomics: Deep-dive protein expression profiling and PTM analysis.
- Global Metabolomics: Discovery-based profiling of cellular or biological fluids.
- Volatile Measurements: Analysis of the volatile organic compound (VOC) profile of biological systems.
- Custom Method Development: If our standard panels don’t fit your needs, we can collaborate to develop and validate novel LC-MS or GC-MS assays tailored to your specific analytes.
