  1. NEXTChem Process Analyzers, Inc.

  2. NEXTChem Process Analyzers, Inc. • NEXTChem is located in Elmhurst IL U.S.A. • Our Mission is to build, support and continuously improve the Best Process Analyzers in the World!

  3. NEXTChem Process Analyzers, Inc. What makes NEXTChem Analyzers different? • Sampling never requires a filter, decreasing maintenance and increasing reliability • Modern electronics makes programming through the User-Interface very simple • Using the latest innovations in stepper motor control for precise chemical analyses • Combining Multiple Chemical Analyses with Multiple Sample Streams within a single unit

  4. Types of Measurement Techniques NEXTChem Process Analyzers, Inc. • Titration Endpoint Determination • (sulfite in sea water) • Standard Addition Ion Selective Electrodes • (ammonia in wastewater)

  5. Types of Titrations NEXTChem Process Analyzers, Inc. • Acid / Base -Acetic Acid • Redox -Sulfide • Complexation -Cyanide • Precipitation -Chloride • Color -Hardness

  6. Three Types of Ion Selective Electrodes Solid State Membrane: The membrane is an insoluble crystal of the ion to be determined. Example: Fluoride, Silver/Sulfide, Chlorine Gas Permeable Membrane: A gas permeable membrane separates the sample from the sensor, commonly pH electrode. Example: Ammonia, Carbon Dioxide Neutral Carrier Membrane: The membrane contains an ion specific complexing agent. Example: Nitrate, Potassium

  7. Color Measurements Color Dip Probe is used for the measurement: 630 nm Red, 590 nm Yellow, 520 nm Green, and 470 nm Blue The following analyses can be done with the color measurements: Total Hardness and Calcium Hardness

  8. NEXTChem Process Analyzers, Inc. HANDYChem 4 Chemical Analyses / 4 Sample Points (industrial/municipal) ECOChem 2 Chemical Analyses / 2 Sample Points (municipal)

  9. NEXTChem Process Analyzers, Inc. CHIPChem 4 Chemical Analyses / 4 Sample Points (semiconductor fabs) MICROChem 2 Chemical Analyses / 1 Sample Point (semiconductor fabs)

  10. NEXTChem Process Analyzers, Inc. TITTREChem 8 Titration Analyses / 4 Standard Addition Analyses No Sample System (manual sample collection)

  11. Many Analyses Available Ammonia (NH3), Nitrate (NO3-), Sulfide (H2S) (Wastewater) Sulfite (SO3-2), Chlorine (Cl2) (Petroleum) Acetic Acid (CH3COOH), Nitric Acid (HNO3) (Chemical) Hardness (Mg+2 & Ca+2), Fluoride (F-) (Drinking Water) Hydroxide Peroxide (H2O2), Caustic (NaOH) (Textile) F/T Acid (H3PO4), F/T Alkalinity (H2CO3) (Metal Finishing) Copper (Cu+2), Silver (Ag+), Cyanide (CN-) (Mining) Ozone (O3), ABC Analysis (S-2/NaOH/CO3-2) (Pulp/Paper) NEXTChem specializes in automating Wet Chemical Analyses!

  12. Industrial Experiences Robert Bosch Wiper Systems: Tienen, Belgium Customer’s Sample: 2.40 g/L chlorine (Cl2) in water Measurement: every 10 minutes Accuracy: + 0.2% relative standard deviation

  13. Measurement Cell Dilution Measurement Cell Non Dilution Measurement Cell

  14. Sample Systems Sample Systems Micro Dilution: 0.25 mL - 2.00 mL (<0.1mm particles) Standard Dilution: 5.0 mL - 30.0 mL (<2mm particles) Standard Non-Dilution: 90 / 140 mL (<3mm particles) Self-Cleaning Non-Dilution: 90 / 140 mL (<6mm particles) Self-Cleaning Dilution: 5.0 mL – 30.0 mL (<6mm particles) All Sample Systems are available for all HANDYChem/ECOChem series analyzers. The MICROChem/CHIPChem series analyzer exclusively use Micro Dilution The TITREChem has no sample system

  15. NEXTChem Process Analyzers, Inc. Why not filter the sample? Filters must be changed frequently Increases Maintenance Lowers Reliability Creates a “fake” Sample “The best filter is no filter” Rob Baur Clean Water Services WEFTEC 1998

  16. Self-Cleaning Sample Valve This valve makes sampling < 6mm particles possible. Most common use is in sewage plants.

  17. Standard Non-Dilution Sample System • Used with Clean and Low Concentration Samples • Commonly used in Drinking Water/Final Effluent Applications

  18. Sample Panel Materials Standard Dilution Sample System • Teflon FEP tubing used in sample panel construction • PVDF is be used for the valve bodies and fittings • Commonly used in Metal Finishing Plants

  19. Sample Panel Materials SC Valve Dilution Sample System • Polypropylene SC Valve ¾” NPT sample opening • PVDF is be used for the valve bodies and fittings • Commonly used in Mining, Pulp & Paper, and Sugar Applications

  20. Sample Panel Materials Micro-Dilution Sample System Used with very clean and very high concentration samples. All “wetted surfaces” PEEK or Teflon Commonly used in the Semiconductor Industry and Chemical Plants

  21. Modern Electronics Why use 1980’s electronics found in most on-line analyzers, when you can have modern electronics?

  22. Modern Electronics Modbus is standard on all NEXTChem Analyzers. Additional Industrial Networks Available Profibus – DP DeviceNet CANopen ControlNet LonWorks CC – Link FIPIO Phone Modems and Radio Modems can also be added

  23. True Remote Access and Control The analyzer is assigned an IP address and connected to the plant network. All the screens on the touch screen are available and interactive, making remote changes possible. Installed at Eastman Chemical in Kingsport, TN USA.

  24. Easy to use touchscreen ! • NO MORE PUSH BUTTONS! • Bright Backlight makes the User Interface easy to read

  25. Precision Reagent Pump • 7.500 mL stroke volume • Accuracy + 0.001 mL • Kalrez Seal for long life (1 year) • Communications confirmed with each movement • Stepper Motor with 8335 steps/mL or • 0.00012 mL/step

  26. Corrosive Environments • NEMA 4X (IP66) Fiberglass Enclosure • Either a Z-Purge, X-Purge, or ATEX-Purge can be supplied • Z-Purge (Class 1 Div 2) • X-Purge (Class 1 Div 1) • ATEX-Purge (Zone 2)

  27. Rugged Electronics • Circuit Breaker for the Power Inlet • Power Filter for the main power in 110 VAC or 220 VAC • Fuses 5mm x 20mm for all internal/external devices • All analog inputs have 1.5 kV isolation • All analog outputs can have 1.5 kV isolation • Industrial Relays with diode protection and easy to replace

  28. Dynamic Electrode Output Display • Electrode measurements are displayed during each analysis • This information is invaluable in determining if the analyzer is operating correctly at a glance
