Problems solved by technology

[0004] If the analysis methods of two eluent systems (that is, dual systems) are applied at the same time, instrument suppliers often recommend two conventional solutions, one is to configure two ion chromatographs; the other is to configure the same ion chromatograph Two independent flow systems (including infusion pumps, analytical columns, suppressors, and conductivity cell detectors). The infusion pumps account for 60% of the value of the main unit of the ion chromatograph. The above two solutions need to be equipped with two Infusion pumps are relatively large in terms of hardware investment costs

Abstract

The method for realizing ion chromatograph switching to use dual systems relates to the technical field of chromatographic analysis. It configures the host of the same ion chromatograph with two suppressors respectively applicable to carbonate eluent and hydroxide eluent, respectively applicable to Two anion analysis columns for carbonate eluent and hydroxide eluent and two general-purpose conductivity cell detectors form flow path I and flow path II. By switching flow path I and flow path II and performing After the washing solution is replaced, the switching between the carbonate eluent analysis system and the hydroxide eluent analysis system can be realized. The method involves less hardware investment cost, simple installation and use methods, and is more convenient to be popularized and used in laboratories with relatively short funds.

Description

technical field [0001] The invention relates to the technical field of chromatographic analysis, in particular to a method for realizing switching of a single ion chromatograph and using dual systems. Background technique [0002] Ion chromatography is an effective high performance liquid chromatography method for the analysis of trace anions or cations. It has the characteristics of high selectivity, high sensitivity, rapidity and simplicity, and can simultaneously analyze a variety of anions or cations. [0003] At present, the analysis methods involving anions in national standards or industry standards mainly include carbonate eluent analysis system method and hydroxide eluent analysis system method. Generally, the same laboratory is equipped with an ion chromatograph, either a carbonate eluent analysis system or a hydroxide eluent analysis system. For the flow path structure of a single system, see figure 1 shown. [0004] If an analytical method using two eluent syst...
