Microfluidic sorting chip, droplet screening method, system, device, and storage medium

A droplet screening system, wherein the system comprises:

• an acquisition module, configured to sample at least two types of electrical signals of a droplet to be detected at a preset frequency, each type of electrical signal of the droplet to be detected being acquired in different analog-to-digital conversion signal channels;
• a determination module, configured to determine a target electrical signal satisfying an intensity threshold among the electrical signals;
• a judgment module, configured to extract features from data of the target electrical signal when a signal width of the target electrical signal satisfies a signal width threshold, judge whether intra-channel features of the target electrical signal satisfy a first preset condition, and judge whether inter-channel features of the target electrical signal satisfy a second preset condition;
• if so, identify the droplet to be detected as a target droplet;
• wherein the intra-channel features are features of the droplet to be detected which correspond to features within each analog-to-digital conversion signal channel, and the inter-channel features are features of the droplet to be detected which correspond to features between each analog-to-digital conversion signal channel.
