A cartridge 300 for capillary electrophoresis includes a housing which includes a base 202 at least partially defining a cavity 250 defining a cavity volume. A cover plate 304 that is secured to the base 202 defines a window. A volume displacement structure 360 projects from at least one of the base 202 and the cover plate 304 and into the cavity 250 when the cover plate is secured to the base. The volume displacement structure 360 and cavity 250 together at least partially define a coolant liquid flow path 366 having a coolant liquid flow path volume less than the cavity volume. A plurality of capillaries 326 is disposed in the coolant liquid flow path. Each of the plurality of capillaries includes a capillary inlet 222 and a capillary outlet 224 projecting from the base.

The proposed development is a rheometer device that simultaneously measures viscosity (μ) and yield strength (to) online, with measurements taken at intervals of a few minutes for mining slurries. Therefore, the design must withstand the typical conditions of a mining operation (extreme temperatures, high altitude, communication problems, distance, extreme humidity, theft, mishandling, etc.). The rheometer in this development is based on the laminar flow transport of the slurry through capillaries. This rheometer measures simultaneously in more than one capillary. The online measurement and data analysis system accounts for the effects of sedimentation, capillary or pipe wall effects, temporal effects (e.g., thixotropy and viscoelasticity), and capillary inlet effects.On the other hand, it considers losses due to changes in diameter, the oscillatory effects of the point generated by the peristaltic pump, and the overreactions generated when the speed changes. A method for operating the rheometer device is also presented.

The invention discloses a planetary atmospheric trace gas in-situ collection device and a detection device and method, and belongs to the field of space detection.

According to the collection device, through the arrangement of the gas inlet pipe of the capillary tube, stable pressure drop of gas entering the filtering tank is achieved, stable gas inlet is achieved, efficient filtering and impurity removal of inlet gas are achieved through the filtering tank, and efficient enrichment of target trace gas is further achieved through the enrichment tank.

The application provides a refrigeration device and a control method of the refrigeration device. The refrigeration device comprises a refrigeration system and a storage chamber. The refrigeration system supplies cold to the storage chamber. The refrigeration system comprises a variable frequency compressor, a condenser, a capillary tube and an evaporator connected in sequence. The refrigeration system further comprises a heat exchanger. The heat exchanger comprises high-temperature heat exchange pipes and low-temperature heat exchange pipes which are arranged in parallel and exchange heat with each other. The inlet of the high-temperature heat exchange pipes is connected with the condenser, and the outlet thereof is connected with the capillary tube. The inlet of the low-temperature heat exchange pipes is connected with the evaporator, and the outlet thereof is connected with the gas return port of the variable frequency compressor. The refrigeration system of the application exchanges heat through the high-temperature heat exchange pipes and the low-temperature heat exchange pipes, so that the refrigerant is first subjected to primary heat exchange and cooling before entering the evaporator, and is first subjected to heat exchange and heating before entering the variable frequency compressor. Therefore, the pressure between the outlet of the variable frequency compressor and the inlet of the capillary tube can be controlled within the range that can be borne by the variable frequency compressor when the refrigeration system is stably operated, and the low-temperature refrigeration below-40 DEG C can be realized.
