1 Scope

This standard specifies the inorganic anion impurities in chemical products was determined by ion chromatography terminology and definitions, the principle of the method, reagents, materials, Instruments, equipment installation and operation methods, qualitative analysis, quantitative analysis, analysis of the results of the general rules expressed in the precision and the like. This standard applies to ion chromatography inorganic anions of various impurities in chemical products (including F-, Cl-, Br-, I-, CN-, CO2-3, NO-2, NO-3, PO3-4, SO2-4, BrO-3, ClO-4, ClO-3, ClO-2, SCN-, N-3, AsO3-3, CrO2-4) quantitative determination .

3 Terms and Definitions

The following terms and definitions apply to this document. 3.1 Ion Chromatography ionchromatography In with the eluent as mobile phase ion exchanger as the stationary phase ion separation column, the sample of the various ions are separated, and then After conductance detectors one kind of liquid chromatography measurement.

4 principle of the method

Samples were prepared as the sample solution, into the ion exchange resin ion exchange column stationary phase, eluted with a suitable eluent, Active exchange groups on the resin with a test solution of ions and the mobile phase eluent ion ion exchange ion exchange occurs. With shower Flow lotion, exchange groups in the test solution with anion exchange resin on the continuous generation - eluting Re - exchange - and then eluting an anion test According to its retention characteristics on different implementations of the separation column, the eluent was eventually brought to the detector is formed Gaussian chromatographic peaks. In a Peak flow time of the components under given chromatographic conditions (ie retention time) is fixed as a basis for the qualitative component ions. In certain concentrated Within the range of component peak area (or height) is proportional to the concentration of the recorder components (such as integrator) to collect quantitative component of this signal is given result.
