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?

It cut down our quarterly 4 days of CN testing to 1 day. Plus it does a good job reducing/elimiting interferences. Check out the webinars from OI Analytical.  http://www.oico.com/default.aspx?id=appcntrwbnrbypl&PLID=16.
