Performance Technique 53 Cause Effect Matrix

Use a Cause Effect Matrix (Technique 53) to determine the relationship between the design s inputs and outputs. If you understand how each input affects the output, both individually and in combination, you can improve your design performance and reduce variability. 

The uncertainty inherent in the matrix effect and interferences causes flow injection analysis (FIA) to be used only for samples with simple matrices. More reliable analytical information is provided by CFA, which is used in quality control to assure the continuous control of very complex matrices. CFA also assures the sampling process by separation techniques, as the system is tandem separation-analysis. For example, the chromatograph that also performs the separation is assured by using an adequate detection system for the analysis of components.
