  • Detecting compounds in microfluidic droplets using mass spectrometry
    Patent number: 10672601
    Abstract: Disclosed herein are devices and methods for detecting compounds in droplets using mass spectrometry. In some embodiments, the device comprises: a microfluidics-MS (microMS) device, wherein the microMS device comprises: a droplet-to-digital microfluidic device, wherein the droplet-to-digital microfluidic device comprises: a glass layer; an electrode layer comprising chrome electrodes etched onto one side of the glass layer; a dielectric layer configured for electrowetting; and a microfluidics layer comprising channels, pockets, and a droplet generator, for example a T-junction droplet generator, wherein the pockets are connected to the channels; and a mass spectrometry plate, wherein the mass spectrometry plate is reversibly sealed to the microfluidic device.
