A GUIDE TO FLOW CHEMISTRY.
The analysis of anions in drinking water has traditionally applied the environmental ion chromatography which has 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. When the samples have dissolved solids and organics the detection limits end up suffering. All this is caused by the dilutions which can be of help when eliminating the interferences. At times, there can be problems with the interferences. Analyzation of the solution can be done with the flow chemistry without requiring any dilution at all. The amount of the nitrite is always interfered by the high concentration of the chloride. One can always decide to preserve any samples of the Nitrate as it always requires 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.
Sulfuric acid and flow methods are in terms while the fluoride only becomes in terms with the determination of the ion chromatography at any level above 1.0mgl. it’s also advisable that they require deviations from the procedures. Since the interferences become more absent, the method of the P of the flow chemistry becomes sensitive too. All the forms of P in a solution can also be determined by the flow chemistry. Determining sulfate in high chloride can be very difficult as the dilutions only brings the scales to be on the 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.
The ion chromatography is an excellent job and it also needs to have a detector with a separate column. The type of the detector is utilized by the flow chemistry methods and the other colors too. The ion chromatography ensures that it provides a way in which the determination of anions and the drinking water are always unsurpassed in a method. Any samples can allow the automated analysis of the samples which can be hard to the non-metals and anions too. Flow chemistry can be done with the automation of extractions, distillations and also the digestion. 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. The samples of the nitrates cannot be preserved since the analysis and the high sulfate needs to have sample dilution.
