1. Unique Selling Points (USP) Decade II Antec BV Zoeterwoude, The Netherlands 1

2. USP (short) -Most sensitive ECD -Most versatile – fits any (U)HPLC -Most referenced, proven track record -5 Years warranty on cell 2

3. Who are our competitors? ESA = number 1 BAS Eicom Dionex Waters (OEM)

4. Antec vs. ESA (Coulometric) faster stability !!! better s/n ratio (=detection limit) amperometric has max. 10% conversion and much smaller we surface area usable range from standard LC to capillary LC 5 years guarantee vs 3 months small samples <10ul 20-500 times more sensitive

5. Amperometric vs Coulometric amperometric  about 5 – 10 % conversion  low noise  best S/N ratio coulometric  highest signal  highest noise  poor S/N ratio Figure from D. M. Morgan and S. G. Weber Anal. Chem., 56, 1984, p. 2560

6. Dual (multi) cell control option Serial mode Parallel mode

7. ESA multi cell configurations Guard cell + analytical cell  Cleaning mobile phase (before injector) Conditioning cell + analytical cell  Cleaning up chromatography

8. ESA Coulochem price

9. Antec v.s.BAS, Eicom, Dionex (amperometric) only Antec has workstation concept Antec has superior detector features (ADF, multi cell, temp control) flow cell, wall jet, 5 year guarantee (GC-WE) usable from standard LC to capillary LC ALEXYS system approach, better detection limits Dionex is amperometric but focused on only carbohydrates and shows much less sensitivity.(flowcell issues)

10. Waters 2465 vs. DECADE II no ADF no multi cell control no Flexcell different specifications (temp stability, range setting) software Empower

11. Conclusion Antec products are competitive Antec products and accessories show better performance Antec is developing products and analyzers to improve the position in relation to the competition You can beat the competition when you are… focussed prepared dedicated
