Abstract

The invention relates to a chip-scale gas-liquid separator and a control system thereof. The chip-scale gas-liquid separator comprises a chip-scale gas-liquid separator and assembly unit, a control interface circuit and a chip-scale gas-liquid separator control system based on FPGA+DSP (field programmable gate array and digital signal processor), wherein the chip-scale gas-liquid separator and assembly unit is used for micro-mixing, micro-reaction and gas-liquid separation of a liquid-liquid fluid system under the micro-volume condition; the interface circuit is connected between the chip-scale gas-liquid separator control system and the chip-scale gas-liquid separator and assembly unit; the chip-scale gas-liquid separator control system is used for generating various control signals required for effective separation of the chip-scale gas-liquid separator and monitoring a gas-liquid interval form in a micro-reaction channel in real time to achieve the best gas-liquid separation effect. The chip-scale gas-liquid separator and the control system thereof provided by the invention can be used for effective mixing and reaction of reaction liquid in a microfluidic chip-atomic fluorescence online combined system for trace element detection, gas-state product enrichment and gas-liquid effective separation.

Problems solved by technology

At present, there is little research work on gas-liquid separation in microfluidic chips. The main reason is that it is difficult to manipulate gas-liquid under micro-volume conditions, and the compressibility of gas makes the flow rate of gas unstable.
