A GUIDE TO FLOW CHEMISTRY.
The ion chromatography in the environment has also been included to the analysis in drinking water whereby all the gaining has been done with the acceptance of the wastewater analysis as well. Some of the anions which are analyzed by this include Bromine, Chlorine, SO4, NO4 and also NO2. The detection limits suffer in case the samples end up having dissolved solids or even organics. When one wants to eliminate the interferences, all it needs is the dilutions. The can be issues with the interferences when relating to the flow chemistry. The method of the flow chemistry can be able to analyze the solution directly without any dilution. The amount of the nitrite is always interfered by the high concentration of the chloride. Since the samples of the nitrates require a high sulfate level of simple dilution, it is also possible to spare and preserve them. The nitrates should be tested before 48hours are over, as they cannot be analyzed by the ion chromatography as well.
The sulfuric acid is always regarding the flow methods since the fluoride can never be in terms with the determination of the ion chromatography at levels which are below 1.0mgl. They also require to have deviations from the procedures which are always followed. However, methods for P of the flow chemistry are always sensitive since the interferences become absent more often. The flow chemistry is also in a position whereby it can determine all forms of P in a solution. Sulfate which is always at low levels is however very difficult to determine in high chloride since the dilutions will bring the scales to be on responses. If it also happens that the samples are analyzed without any dilutions, the high content in salt ends up causing retention which also makes the sulfate to be identified as phosphate by other data systems.
Even though the ion chromatography is an excellent method, it also needs to have a detector which is accompanied by a separate column than having the use of anions. The flow chemistry methods always utilizes the type of the detector the same way it utilizes the other color methods as well. The ion chromatography provides a way as well whereby the determination of the anions and the drinking water are unsurpassed. Automated analysis can be allowed by the flow analysis as well since it can allow automated samples which at times becomes more difficult for the non-metals and anions as well. Distillations, digestion and extraction of the automation needs the flow chemistry. The level of the chloride can be prevented by dilutions which are high so that the aluminium and copper can also be diluted hence destroying the column of the ion chromatography. In as much as the samples are adjusted neutral to all the analysis, they cannot be preserved since sulfate always require sample dilution.
