Mass Frontier - How to predict contamination October 14, 2013, 02:26:18 AM I'm a new Mass Frontier user and would like to know if it is possible to predict/identify the contamination of a sample (or to give a ranking of possibilities) having the m/z of the compound and fragmentations and having no idea of what contamination could it be. If you could tell me how to do it I would appreciate it.Thank you very much. Quote Selected
