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, and belongs to the field of high grade biochemistry analysis and fluid micro mixing in micro-complete analysis systems. The high performance micro-mixer comprises two inlet channels, a mixing chamber, twelve blocking plates which are distributed in an up-down staggered manner, and an outlet channel; the blocking plates are capable of enhancing the convection effect in solvent flowing, so that it is convenient for forming of a vortex zone; and in addition, the staggered blocking plates are capable of realizing flow of mixed solvent in the mixing chamber in a square wave patter path, and vortex is easily formed at corners, the existing of vortex is capable of breaking laminar flow state of solvent in flowing, and delaying diffusion path of mixed solvent in the mixing chamber, the mixing performance of the high performance micro-mixer is improved obviously, and the precision of the ultra-high performance liquid chromatography analyzer is increased further.

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...
