1、 Introduction to Working Principle

Through continuous flow, true fully automated analysis and testing have been achieved. Through technological optimization, Proxima provides an ideal solution for water quality, soil, plant analysis and testing, and all analysis methods comply with current international norms and standards; The system is highly automated, modular, and integrated, and can install up to 5 channel modules to form a multi-channel analysis system.

The continuous flow analyzer of fragmented flow technology utilizes sample solutions continuously drawn from various reagent containers, mixes and reacts with reagents in the flow path system, and finally reaches the detector to complete the analysis process of detection. The entire process is fully automated, with ultra-low detection limits and low reagent consumption; More than 1000 application methods have been established, most of which are analysis methods recognized by international authoritative institutions. The system channel can be increased to 5 channels, which can simultaneously detect different indicators.
