<p>A method and apparatus for extracting proteins, peptides and other substances from a sample so as to prepare the sample for subsequent analysis by analytic or diagnostic methods such as mass spectrometry. More particularly, a method and apparatus for preparing a peptide extract from a complex biological sample. The sample containing, among other things, peptides, proteins and salts. The method first filters the sample and subsequently subjects the filtered sample to chromatography. The method is performed using a filtration unit, a chromatography unit, and a unit to hold the final extract of the processed sample, all which fit into one another and finally fit into a centrifuge.</p> |
