A GUIDE TO FLOW CHEMISTRY.
Traditionally, the analysis of the anions in drinking water has been applied to the ion chromatography which has always been gaining all the acceptance of the wastewater analysis. 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 interferences can, however, cause problems when it comes to the flow chemistry ways. 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. Its also advisable for the samples of the nitrates to be preserved since they all require a high sulfate level of a sample dilution. Since preserved samples can never be analyzed by the ion chromatography, Nitrates should always be tested before 48hours are over.
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. Method for P of the flow chemistry is however sensitive to the interference may become absent most of the time. Flow chemistry can easily determine on the 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. The content in the salt may end up bringing retention if the samples are not analyzed without having any dilution as the sulfate can be identified as phosphate from other data systems.
The ion chromatography is an excellent job and it also needs to have a detector with a separate column. 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. The flow chemistry can allow automated analysis of any samples which might be difficult for the non- metals and also anions too. Automation of distillations,extractions and even the digestions can also be done with flow chemistry. Accurate level of the chloride can be prevented by high dilutions so as to be able to dilute copper, Aluminium,and also destroy the column of the ion chromatography. The samples of the nitrates cannot be preserved since the analysis and the high sulfate needs to have sample dilution.
