pressure injection cell : ウィキペディア英語版 | pressure injection cell
Pressure Injection Cells, sometimes referred to as "bomb-loading devices" are used in proteomic research to enable controlled dispensing of small-volume liquid samples. ==Applications== Using high pressure, pressure injection cells are used for two applications: densely packing nanobore capillary columns (micro-columns) with solid-phase particles for use in LC/MS analysis; and precisely infusing microliter samples directly from microcentrifuge tubes into mass spectrometers without additional transfers, wasted sample, or contact with metallic surfaces which adsorb some negatively charged molecules such as phosphopeptides.〔Watson, J.
