Systems and methods for performing measurements of one or more materials
Systems and methods for performing measurements of one or more materials are provided. One system is configured to transfer one or more materials to an imaging volume of a measurement device from one or more storage vessels. Another system is configured to image one or more materials in an imaging volume of a measurement device. An additional system is configured to substantially immobilize one or more materials in an imaging volume of a measurement device. A further system is configured to transfer one or more materials to an imaging volume of a measurement device from one or more storage vessels, to image the one or more materials in the imaging volume, to substantially immobilize the one or more materials in the imaging volume, or some combination thereof.
1. A system comprising:
a fluidic flow-through chamber;
a magnet and a mechanism for selectively positioning the magnet in proximity to an imaging region of the fluidic flow-through chamber;
an illumination subsystem configured to illuminate the imaging region of the fluidic flow-through chamber; and
a photosensitive detection subsystem configured to image the imaging region of the fluidic flow-through chamber when illuminated,
wherein the photosensitive detection subsystem comprises a photosensitive detector, and
a temperature sensor configured for detecting a temperature of the photosensitive detection subsystem; and
a processor coupled to the temperature sensor, including a non-transitory memory device encoded with program instructions for regulating integration time of the photosensitive detector, wherein the integration time is an amount of time over which the photosensitive detector collects image data for a single image, the program instructions for regulating the integration time of the photosensitive detector comprising:
recording a base temperature of the photosensitive detection subsystem via the processor;
monitoring the temperature of the photosensitive detection subsystem via the processor; and
adjusting the integration time of the photosensitive detector upon detecting a temperature change greater than a preset threshold.
2. The system of claim 1 , wherein the program instructions for adjusting the integration time of the photosensitive detector comprises program instructions for adjusting the integration time of the photosensitive detector by an amount proportional to the detected temperature change.
3. The system of claim 1 , wherein the program instructions for adjusting the integration time of the photosensitive detector comprises instructions for recording a base temperature of an imaging system while a sample is being injected into the fluidic flow-through chamber.
4. The system of claim 3 , wherein the program instructions for adjusting the integration time of the photosensitive detector comprises instructions for monitoring the temperature of the system while the sample is being processed and analyzed in the fluidic flow-through chamber.
5. The system of claim 4 , wherein the program instructions for adjusting the integration time of the photosensitive detector comprises instructions for adjusting the integration time of the photosensitive detector upon detecting a temperature change greater than a preset threshold.
