1. A system comprising a fluid sampling tool comprising:
at least one probe in fluid communication with a formation;
at least one passageway that passes through the at least one probe and into the fluid sampling tool;
at least one fluid sampling vessel, wherein the fluid sampling vessel comprises at least one removable cartridge in fluid communication with the at least one probe through the at least one passageway, wherein the removable cartridge has a bore section suitable to be isolated from fluid passageway, wherein the bore section has a fluid inlet and a fluid outlet located in between two seals;
a rod inside removable cartridge that has a storage cavity for fluid storage protected on either side by seals with a seal to prevent fluid communication between fluid sampling vessel exterior and the at least one passageway and a seal to prevent fluid communication between fluid sampling vessel interior and the at least one passageway, wherein the rod can be shifted upward by hydraulic oil through a port and lock the rod into a captured sample position;
at least one electrically or hydraulically actuated valve connected to the at least one fluid sampling vessel; and
an electric motor-driven hydraulic pump connected to at least one bus and to the at least one fluid sampling vessel through the at least one electrically or hydraulically actuated valve.
