A method and system for obtaining samples for proteomic analysis that utilizes pressure and a preselected agent to obtain a processing sample in a significantly shorter period of time than prior art methods and which maintains the integrity of the processing sample through the preparatory process. In one embodiment of the invention, a sample and an enzyme are combined and subjected to a pressure, preferably a pressure cycle range that varies between 0 to 35 kpsi, for a period of time of preferably less than 60 seconds. This process results in producing a sample suitable for analysis, which is preferably introduced to another analytical instrument such as a mass spectrometry instrument, or other device.
