Benefits of technology

This patented method involves combining two types of analyzers together that work separately on specific molecules called anion species. By doing this, they have several technical benefits such as simplified design, stability over long periods without losing their accuracy or resolution ability due to factors like temperature changes during use. Additionally, these methods are cost-effective compared to other technologies used alone.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the performance of replacing or interchanging electrodes in liquid chloride extraction cells during mass spectetry measurements.

Abstract

The invention provides an analysis device for detecting multiple anions simultaneously. The analysis device comprises an ion chromatography separating system and a liquid cathode glow discharge atomic emission spectroscopy detecting system. The ion chromatography separating system comprises a chromatographic pump for conveying a mobile phase, a leacheate generator, a six-way injection valve, a guard column, a separation column, an ion suppressor and a cation exchange column. The liquid cathode glow discharge atomic emission spectroscopy detecting system comprises a sample injection unit, a light source generating part generating glow discharge, a light split unit for carrying out light splitting treatment on a glow discharge emission spectrum, a detecting unit for detecting the emission spectrum obtained after light splitting treatment, and a data processing unit for analyzing data generated by the detecting unit. The ion chromatography separating system and the liquid cathode glow discharge atomic emission spectroscopy detecting system are combined for use, the analyzing process comprises separation of anions, conductive background suppression and ion conversion, the overall structure is simple, the performance is stable, and the price is low.
