A small scale (5 kJ stored electrical energy) gas puff z-pinch device has been used as an intense tunable flash x-ray source for high-resolution (15-nm spatial resolution) contact microscopy of unstained biological specimens. The selection of gas injected into the device to form the plasma determined the radiated spectrum. When the gas was varied, areas of different chemical composition within the specimens were selectively imaged.
