Abstract
The invention provides devices and methods for linked multimodal measurements of individual particles using a mass sensor and an additional sensor.
Claims25
A measurement device for assessing properties of particles suspended in a fluid, the measurement device comprising:
- a measurement channel comprising a mass sensor to measure particle mass and an imaging sensor in a sensor region at least, wherein a particle flows through the measurement channel and sensor region, wherein the measurement device:
- obtains a plurality of images of the particle as it flows over through the sensor region and identifies the particle entering the mass sensor;
- determines a flow velocity of the particle using a positional change of the particle between images;
- uses the flow velocity of the particle to project a time at which the particle flows through the mass sensor for measurement;
- and
- correlates a measurement obtained using the mass sensor with the identity of the particle based on the projected time.

A measurement device for assessing properties of particles suspended in a fluid, the measurement device comprising:
- a measurement channel comprising a sensor to measure particle mass through which a particle flows and at least one additional sensor that detects the orientation of a particle in the measurement channel using the additional sensor.
A measurement device for assessing properties of particles suspended in a fluid, the measurement device comprising:
- a measurement channel comprising a sensor to measure particle mass and at least one additional sensor to measure an additional particle property,
- wherein the additional sensor detects the particle entering the mass sensor with one or more other particles and the measurement device uses data from the additional sensor to isolate a measurement for the particle from a multi-peak measurement obtained by the mass sensor due to the particle and the one or more other particles flowing through the mass sensor.
