Design and a ssembly of the CHeES nozzle. Narrow 40 µm and 75 µm inner diameter lines minimize inner sample and outer coaxial-liquid-sheet dead volumes. (a) CAD-design with color coded inlet capillaries and (b) stereomicrograph of an assembled nozzle. (c) Bright-field microscopy image of a CHeES nozzle in operation, forming a Taylor cone at the nozzle orifice. (d) Scanning electron microscopy confirmed accurate fabrication of the fine features of the nozzle orifice used to form a conductive liquid sheet around the sample stream in the Taylor cone, giving CHeES more stable operating characteristics compared with conventional electrospray nozzles (e), which are prone to clogging from non-volatile solutes deposition on the orifice over time. Scanning electron micrographs indicate extensive sucrose deposits (f) on the orifice after clogging from spraying 1% v/v sucrose buffer for about an hour.
