Application of Ion Chromatography in Environmental Analysis - 1

INDUSTRY APPLICATION SOLUTIONS Surface water is generally relatively clean. After 30 minutes of natural precipitation, taking the non precipitation part of the upper layer for analysis. If there are many suspended substances in the water sample or the color is darker, pretreat it by centrifugation, filtration or steam distillation. Using CIC-D120 ion chromatograph, SH-AC-3 anion column, 3.6 mM Na2C03+4.5 mM NaHC03 eluent and bipolar pulse conductance method,under the recommended chromatographic conditions,the chromatogram is as follows. The environmental samples of a certain volume ortime are collected according to the sampling requirements of TSP, PM10, natural dust and dust storms in the atmosphere. A quarter of the filter membrane samples collected are accurately cut into plastic bottles,adding20mL deionized water ;then volumed to 50mL after beening extracted in the ultrasonic cleaner and filtered by a 0.45pm microporous filter membrane. After all this,the sample can be injected for analysis. Using CIC-D120 ion chromatograph, SH-AC-3 anion column, 3.6 mM Na2C03+4.5 mM NaHC03 eluent and bipolar pulse conductance method,under the recommended chromatographic conditions, the chromatogram is as follows. Using CIC-D120 ion chromatograph, SH-CC-3 cation column, 5.5 mM MSA eluent and bipolar pulse conductance method,under the recommended chromatographic conditions, the chromatogram is as follows.
