Hi,
I hope you are well. I want to perform a screening experiment to understand which materials in the formulation are impacting the response. There are a number of materials I want to study the impact of (10 in total), however, in any given formulation there are combinations of materials that we can't accept. I've expressed this below, as we only want only one from the following A, B, C, D, E, and F in any formulation test. When the materials are in total, 1A or 2A, 1B or 2B, 1C or 2C, 1D or 2D, 1E or 2E. Note each material described as 1A, 1B or 2B etc... is unique and has varying concentration limits.
How do I create the DoE using custom screen or definitive screen (whichevers best) to measure the impact of these materials?
Thank you very much
