Hi, as I've stated before I am doing research in the area of jet fuel contamination. However I have shifted my focus to methods of testing. I know many of you work in the aerospace industry. What I need to know if there are any "popular" or "standard" methods you use at your company or perhaps any other information useful on testing. My aim is to find out what method(s) would be suitable for private jet owners weighing factors such as cost, time, frequency of testing etc.. Thank you for your time.
