A high-performance micro-mixer used in ultra-high performance liquid chromatography analyzer

Abstract

The invention discloses a high-performance micro-mixer used in an ultra-high performance liquid chromatography analyzer, which belongs to the field of fluid micro-mixing in high-end biochemical analysis and micro-total analysis systems and related fields. The micro-mixer includes two inlet channels, a mixing chamber, twelve baffles staggered up and down, and an outlet channel; the existence of baffles enhances the convection effect of solvent flow, and is easy to form a vortex area. In addition, the baffles staggered The plate makes the mixed solvent flow in a square wave path in the mixing chamber, and vortices are also easy to form at the corners. The existence of the vortex can break the laminar flow state of the solvent flow and prolong the diffusion path of the mixed solvent in the mixing chamber, which significantly enhances micro The mixing performance of the mixer further improves the precision of the ultra-high performance liquid chromatography analyzer.

Description

technical field [0001] The invention relates to a micro-mixer in an ultra-high performance liquid chromatography analyzer, which has higher mixing performance. The invention belongs to the field of fluid micro-mixing in high-end biochemical analysis and micro-total analysis systems. Background technique [0002] Ultra-high performance liquid chromatography (UPLC) is an important means to solve problems such as drug analysis, biochemical analysis, blood testing and environmental testing, and plays an important role in improving drug treatment capabilities and enhancing disease analysis capabilities. The instrument is rapidly used in food safety, environment, pharmaceuticals, scientific research and other fields. Despite the rapid development of ultra-high performance liquid chromatography, the high-precision reagent delivery system in it lacks a matching supplier and a complete supply chain solution, and its flow accuracy, accuracy, pressure pulsation and system delay volume...
