I am interested in doing some of the amino acids on my CE that are troublesome or impossible using GC (arginine serine threonine). I am looking at the NDA protocol and the problem I see is the use of sodium or potassium cyanide. I already push the limits with chloroform and the chloroformate derivatizing agents I don't think safety is going to let me order cyanide. Is there a viable, safer alternative?
