The time resolution is 15 min;
Automatic configuration of six way valve;
The anion and cation chromatographic columns are all original imported components, and the inlet of flow path is equipped with imported cation and anion protection columns, which can effectively prolong the service life of chromatographic column and improve the separation peak type.
Constant temperature control of flow paths such as anion and cation chromatography column, protection column, conductivity detector, suppressor, etc. is controlled at 40 ℃ to ensure the baseline stability;
The suppressor current is controlled by synchronous chromatographic pump to protect the suppressor. When the chromatographic pump delivers eluent, the suppressor current is turned on as required. When the chromatographic pump stops delivering the eluent, the suppressor current is turned off;
Equipped with imported on-line degasser, the micro bubbles in the eluent can be removed in real time to ensure the stable pressure and flow rate of chromatographic pump;
PEEK material is used in high pressure reciprocating pump, which has no effect on the sample;
Th-980h is an equal concentration conveying system, that is, the composition and concentration of the eluent do not change during operation.

Th-980h continuous determination instrument for water-soluble ions of atmospheric fine particles is a water-soluble anion and anion automatic continuous analyzer independently developed by our company with independent intellectual property rights. It is suitable for laboratory and online analysis of anions and cations. Refer to the requirements of jjg823-2014 ion chromatograph.
