Sample preparation

Small chemicals and macromolecules analysis in complex matrices.

  • Environmental et food industry analysis:

Liquid/liquid extraction, Soxhlet, solid phase extraction/purification (SPE, SPME, SBSE).

Mass content of lipids, sugars, protéins, water.

  • Microbiology analyses:

Selective metabolite extractions (lipids, polar, volatile) after quenching the metabolism. Acid hydrolys of proteins (total amino acids).

  • Macromolecules preparation:

Proteins reduction, carbamidomethylation then in gel digestion (bottom-up shotgun identification, Peptide Mass Fingerprinting).
