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

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

DESI Mass Spectrometry Imaging

Desorption electrospray ionization mass spectrometry imaging (DESI-MSI) enables direct molecular analysis of tissue sections without extraction or staining. The technique generates spatial maps showing the distribution and localization of lipids, metabolites, drugs, and small molecules across tissue sections while preserving tissue morphology.

We use DESI-MSI for both untargeted molecular profiling and targeted imaging workflows in fresh-frozen and OCT-embedded tissues, including tumor samples and 3D spheroid models. Molecular images can also be aligned with histological stains such as H&E for direct comparison with tissue structure and pathology.

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.
