Abstract

The invention belongs to the technical field of water quality analysis and environment protection, is applied to analysis on anions and cations in common water quality and relates to a mobile type anion and cation analysis device for analyzing concentrations of anions and cations in water quality samples. The device comprises a shell, a leacheate bottle, a plunger pump, a capturing column, a leacheate generator, a self-regeneration capturing column, a degassing box, a six-way valve, a protection column, an analysis column, an inhibitor, an electric conductivity detector, a UPS (Uninterrupted Power Supply) power supply, a cabinet door and a meter head. By adopting the analysis device, leacheate in the leacheate bottle is fed through the capturing column, the leacheate generator, the self-regeneration capturing column, the degassing box, the six-way valve, the protection column, the analysis column, the inhibitor and the electric conductivity detector in sequence through the plunger pump, and sample analysis is achieved in analysis modes of the six-way valve.

Description

technical field [0001] The invention belongs to the technical field of water quality analysis and environmental protection, is applied to the analysis of anions and cations in conventional water quality, and relates to a mobile anion and cation analysis device. Background technique [0002] In the conventional technical scheme, the anions and cations in the water quality are analyzed on-line and off-line. On-line analysis adopts continuous monitoring of online instruments; offline analysis adopts manual sampling, laboratory analysis or on-site analysis of portable instruments. A small number of anions and cations can be continuously monitored by online instruments, and the detection limit is limited. For low-content anions and cations, online analysis methods cannot be used. Therefore, most of the anions and cations need to be manually sampled and laboratory offline analysis methods. [0003] However, laboratory offline analysis has the disadvantages of long analysis time, ...
