  • SINGLE PIECE DROPLET GENERATION AND INJECTION DEVICE FOR SERIAL CRYSTALLOGRAPHY
    Publication number: 20230243765
    Abstract: A single-piece hybrid droplet generator and nozzle component for serial crystallography. The single-piece hybrid droplet generator component including an internally-formed droplet-generation channel, an internally-formed sample channel, a nozzle, and a pair of electrode chambers. The droplet-generation channel extends from a first fluid inlet opening to the nozzle. The sample channel extends from a second fluid inlet opening to the droplet-generation channel and joins the droplet-generation channel at a junction. The nozzle is configured to eject a stream of segmented aqueous droplets in a carrier fluid from the droplet-generation channel through a nozzle opening of the single-piece component. The pair of electrode chambers are positioned adjacent to the droplet-generation channel near the junction between the droplet-generation channel and the sample channel.
