1 Cyanide Analysis with the CNSolution 3100

2 The CNSolution is your solution to cyanide analysis Gas diffusion amperometry methods: Save time Save money Are more accurate Have fewer interferences Are green The CNSolution = the FS3100 Change to a photometric detector and run any colorimetric chemistry

3 Cyanide Methods

4 Cyanide methods measure the various cyanide species Strong Metal Complexes Fe, Co, Pt, Au Total CN Available CN Weak to Moderately Strong Metal Complexes Ag, Cd, Cu, Hg, Ni, Zn Free CN HCN CN -

5 Manual distillation is used to dissociate as HCN Macro Distillation MIDI Distillations

6 Cyanide methods that utilize distillation have significant disadvantages Time Consuming One hour long distillation (does not take into account setup and teardown) CATC requires two, one hour distillations Bulky and Relatively Expensive Glassware Operator-dependent results (technique) Multiple Interferences

7 Gas diffusion eliminates distillation and associated cost Lowest cost Dollars per Year Consumables + labor per year MicroDist Midi Dist CNSolution

8 Samples per 8 hour Shift Eliminating distillation increases laboratory capacity 800 Highest sample capacity Midi Dist Micro Dist CNSolution

17 Ligand Exchange GD-amperometry methods have fewer interferences CATC WAD OIA 1677 N-organics SCN,NH 3,NO 2 Excessive Iron Cyanide Concentration Dependent None S 2 O 3, H 2 O 2 Concentration Dependent

18 Ligand Exchange GD-amperometry methods give you results in minutes CATC WAD OIA 1677 Sample Preparation 2 distillations 2 3 hours 1 distillation 2 3 hours No distillation Analysis 1 2 minutes 1 2 minutes 1 2 minutes Total Time 3 4 hours 3 4 hours 1 2 minutes

19 Samples per hour Ligand Exchange GD-amperometry methods means more samples samples per hour Distillation Diffusion 20 0

20 Ligand Exchange GD-amperometry methods provide the best benefits No distillation (eliminates 1 4 hours preliminary sample treatment) Low MDL (0.5 ppb) No Interferences High Throughput (up to 90 samples per hour) Ease of Operation, very simple chemistry.

21 Total Cyanide Methods Automated gas diffusion distillation and nondistillation methods

22 GD-amperometry provides the safest, easiest, and most accurate technique No pyridine Acid Reagent ASTM D is a green chemistry

23 ASTM D7511 is easy to understand and operate and does not distill. No pyridine Green Chemistry
