Tales of Chemists:
The Metals Story
"I had to analyze a variety of transition metah at extremely low concentration leveL·. Interferences were always a problem" "We needed to increase the efficiency of our electroless nickel plating solution for the manufacture of magnetic storage media. AA and ICP had extreme interference problems. To my delight, I discovered that a Dionex Ion Chromatograph could analyze and speciate metals and other ions according to their oxidation states. Finally we can see 100 ppb lead in 1000 ppm nickel! "Our Dionex virtually eliminated the old interference problems and gave us the sensitivity we needed to improve our production yields. Now we even do our routine wastewater samples on our Dionex"
