When normalized component amounts aren’t correct, it is almost always because there is a problem with one or more of the raw component amounts reported by the chromatography data system.
1) First, check the total raw (un-normalized) amount. It should be within a few percent of 100%. If the total raw amount is either too low or too high, it will throw off all of the normalized component amounts.
2) If the total raw amount is not within a few percent of 100%, then you need to examine the raw component amounts and find the result(s) that are incorrect. You can review raw amounts in EZReporter by enabling the raw component amount result in the configuration editor, or you can review the results in the chromatography data system.
Important: normalization assumes that you are reporting all components that are present in the sample. If your sample contains significant amounts of a component that isn’t being reported, then it will also throw off your results.
3) Once you find and fix the problem with the raw component results reported by the chromatography data system, your normalized results should also be corrected.
