Full-Service Analysis
The Mass Spectrometry & MS Imaging Facility provides analytical support to researchers at Columbia University and external collaborators. We offer both full-service analysis and self-service instrument access depending on project needs.
For full-service projects, facility staff perform sample preparation, LC-MS or MS imaging data acquisition, and data analysis. We work closely with researchers to select appropriate methods and instrumentation for each study.
Lipidomics & Metabolomics
Lipids and small-molecule metabolites play important roles in cell signaling, energy metabolism, and disease biology. We use high-resolution LC-MS/MS to profile complex biological samples for both untargeted discovery and targeted quantitative studies.
Services include:
- Untargeted lipidomic and metabolomic profiling
- Targeted analysis of lipid classes and metabolite panels
- Comparative studies across tissues and biofluids
- Biomarker and metabolic pathway studies
Compatible sample types:
Cells, fresh-frozen tissue, OCT-embedded tissue, plasma, serum, and urine
Targeted Drug Quantification
Quantitative analysis of drugs and their metabolites is important for pharmacokinetic studies, drug development, and clinical research. We use triple-quadrupole LC-MS/MS with MRM detection for sensitive and selective analysis in plasma, urine, tissue, and other complex biological samples.
Services include:
- MRM-based quantitative analysis
- Calibration curve and internal standard workflows
- Pharmacokinetic and drug metabolism studies
- Method development and validation
Dexamethasone quantification by LC-MS/MS: perilymphatic concentration comparison and standard curve
PFAS & Environmental Contaminant Analysis
Per- and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants that can accumulate in biological and environmental samples at trace levels. We use targeted LC-MS/MS with MRM workflows for sensitive detection and quantification in complex matrices.
Services include:
- Targeted PFAS quantification (including PFOA, PFOS, and expanded panels)
- Analysis of water, plasma, serum, tissue, and environmental samples
- Method development for emerging contaminants
- Exposure and biomonitoring studies
LC–MS/MS MRM chromatogram overlay of selected PFAS standards showing baseline separation across retention times 4–16 min.
DESI Mass Spectrometry Imaging
Desorption electrospray ionization (DESI) mass spectrometry imaging enables label-free molecular mapping directly from tissue sections without extraction or derivatization. We use DESI-MSI for spatial lipidomics, metabolomics, and drug distribution studies.
Services include:
- Spatial lipidomics and metabolite imaging
- Label-free molecular imaging from tissue sections
- Molecular mapping across tumor margins and tissue compartments
- Co-registration with histological images
- Targeted imaging and relative quantification workflows
Typical spatial resolution:
40–50 μm
Self-Service Access & Training
Select instruments are available for independent use by trained researchers. After an onboarding session with facility staff, users can schedule instrument time and run samples independently.
