Abstract: A spray-capillary device is configured to process ultra low-volume samples. The spray-capillary device includes a spray capillary that includes an inlet end and a discharge end. The spray capillary includes a porous section at the discharge end. A downstream connector provides an interface between the porous section of the spray capillary, a conductive fluid, and a high voltage electrical source. The application of voltage to the downstream connector causes electrospray ionization, which can be used to draw ultra law volume samples into the inlet end. A gas injection assembly can be used to increase the pressure on the inlet end of the spray capillary to encourage movement of the sample through the spray capillary. The spray-capillary device is well suited for providing ultra low samples to a mass spectrometer detection device.
