I made an error in my earlier statements it is ION Selective Electrode.. A little embarassing for me actually, and the meter to achieve PPM must take the Electrical Conductivity and converts that to PPM.. EC/TDS/PPM is all using the same principal to achieve the number.. That in fact makes EC the same thing if you know the conversion rate you can exactly find the EC of that meter...
ION Selective electrodes are sold for almost all the elements I believe although trace elements would be hard to split hairs that far on? I dunno you can search.. try googling ion selective electrode nitrogen
