Hi ElMaestro,
IMHO, calculating the S:N is no more than a finger excercise unless required by the method (e.g., traces in accredited environmental analysis where a true blank matrix does not exist). In bioanalytical methods I'm not sure whether it should be part of an (optional anyway) system suitability test. Playing the devil's advocate - two methods, A/P at the LLOQ 20/20%, S/N 10 or 15/15 5?
