Cyanide By Proposed ASTM D7511-09
Our lab does just enough CN analyses to be taking a strong look at this OI/ASTM method that's in the EPA 9/23/10 proposed update to 40 CFR 136.
Does anybody out there have experience with doing CN by segmented flow analyzer via UV digestion followed by amperometric detection? Does it really do a good job avoiding interferences? How about saving time? Does anybody have any return-on-investment data?
