Abstract

The present invention relates to a droplet injector and a droplet injection method using the droplet injector. The droplet injector is a droplet injector used in the field of microfluid control, and the droplet injector can transfer a small amount liquid sample from an open system to a closed micro-pipe system, especially packs, in the form of water-in-oil, the small amount liquid sample into medium oil to transport in the micro-pipe system. The droplet injector includes a sample channel for drawing in and transporting the liquid sample and a medium channel for pushing a medium, the sample channel is connected with a module that provides a negative pressure, a medium channel is connected with a module that provides a positive pressure, and the sample channel and the medium channel are in fluid communication.

Description

technical field [0001] The invention relates to a droplet sampler and a droplet sampler using the droplet sampler, especially a droplet sampler used in the field of microfluidics, which can transfer a small amount of liquid samples from an open system to a closed microchannel The system, especially in the form of a liquid sample in a medium, such as water-in-oil, encapsulates a small amount of liquid sample in a medium, such as oil droplets, and transports it in a micro-channel system. Background technique [0002] Microfluidic chip technology is widely used in sample preparation, reaction, separation, and detection in biological, chemical, and medical analysis processes. It is one of the most rapidly developing cutting-edge technologies and the most active fields of research. The manipulation of liquid samples is very important in the fields of chemistry, microbiology, biochemistry, molecular biology, and medical analysis. Liquid samples can be, for example, cell culture f...
