FIELD: measurement equipment.
SUBSTANCE: invention relates to a method and a system for analysis of fluid properties of a microfluidic device. Fluid is added under pressure to a microchannel, and phase states of fluid are optically detected in a number of places located along the microchannel. Gaseous and liquid phases of fluid are detected based on a variety of digital images of fluid in a microchannel. Two-level images can be created based on digital images, and a portion of liquid or gas in fluid depending on pressure can be evaluated on the basis of two-level images.
EFFECT: based on detected phase states of fluid, properties can be evaluated, such as values at the initial boiling point and/or distribution of volumetric ratio of fluid phases depending on pressure.
