FIMM Metabolomics/Lipidomics/Fluxomics Unit (FIMM Meta)


Welcome to FIMM Metabolomics Unit (FIMM-Meta)

FIMM Metabolomics/Lipidomics/Fluxomics Unit, a core service facility, and member of the Biocentrer Finland and HiLIFE national infrastructure networks. Our technology platform offers services to researchers in many diverse scientific fields. Our core facility provides high-throughput mass spectrometry based targeted quantitative and global metabolomics/lipidomics and fluxomics services to basic, biomedical, preclinical and clinical researchers. We provide rapid analysis services for metabolites and lipids from different biological classes and various types of samples (biofluids, dried blood spots, cells, extracellular vesicles, cell organelle isolates, tissues, stool, biofilm, dental carries etc.) from humans, animal models (mouse, rat, dog etc.), C.elegans, drosophila, bacteria and yeast etc.


High-throughput tar­geted and quant­it­at­ive metabolomics

Analysis of hundreds of polar metabolites in a single method using MRM strategy. Suitable for tissues, cells, and biofluids.

Customized targeted quantitative metabolomics

Concentration analysis for ketonebodies, ketoacids, NADs, short-chain fatty acids, folate cycle intermediates or absolute quantification of TCA cycle intermediates. Suitable for tissues, cells, and biofluids.

High-throughput qual­it­at­ive metabolomics profiling and custom sets

Qualitative analysis of more than five hundred known standardized metabolites using high-resolution orbitrap Q-Exactive. Suitable also for small sample amounts (i.e. 30 000 cells or 15ul) for biofluids, tissues, cells, stem cells, organoids, spheres, and extracellular vesicles.

Metabolic flux analysis 

Isotope enrichment analysis and metabolic flux analysis of central carbon metabolism and other pathways using 13C-, 15N- and dH-tracers. Suitable also for small sample amounts (i.e. 30 000 cells or 10ul) for biofluids, tissues, cells, immune cells, stem cells, organoids, spheres, and extracellular vesicles.

High-through­put tar­geted and quant­it­at­ive lipidom­ics

Analysis of thousand lipid molecular species in a single method using the Lipidyzer platform. Suitable for biofluids (min 25ul), tissues, cells, and extracellular vesicles. More details (

Data analysis 

We offer via collaboration complete metabolomics/lipidomics data analysis using advanced biostatistical and chemometric methods including integrated omics data analysis, figures, tables, and metabolic pathway analysis. Reporting, data quality checks, and documentation are included in the service.

General Instructions.

Sample Collections:  Quenching protocols for cell samples will be provided.
Sample storage:  Please store the samples at -80°C immediately after the collection.
Sample delivery:  Please deliver the frozen samples on dry ice to us.
Sample tubes:  If you are freshly collecting the samples then we would prefer to have the samples in 1.5 ml eppendorf tubes. If samples are already collected and stored in other types of tubes, no problem we can transfer them here.
Sample list:  Please send us the sample list on email in an excel file format with all the relevant details i.e., sample names, genotype, phenotype, type of sample, oganism, age, gender, treatment information (dietary or drug), available clinical data, time series data, additional information, tissue weights, cell number, protein quantification if available, if you would like to have your extra samples back or not etc.

Pricing is established according to University of Helsinki pricing guidlines, and rates per sample cover running costs, salaries of personnel, instrument maintenance and service contracts.

Pricing is subsidised for population cohorts (> 300 samples). Price rates vary for different samples types due to distinct extraction procedures.
