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 Chemical Measurements with Process Control in 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. Titration Curve – Response vs. Concentration At the point of maximum change in sensor response (endpoint) the sample concentration is zero!

6. Smallest Addition Small Addition Large Addition Typical Titration Curve The reagent additions are controlled by distance from endpoint for maximum accuracy.

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

8. 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

9. The characteristics of the ISE are described by the Nernst equation The Nernst equation : E = E0 + RT ln(10) log (c) nF E = Offset + Slope . log (c)

10. Example of Standard Addition Curve Response due to Sample Response due To Spike Calibration

11. 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, Calcium Hardness, Phosphate, Manganese (II) and Zinc

17. Industrial Experiences Saudi Aramco: Dammam, Saudi Arabia Customer’s Sample: 50 ppm Sulfite (SO3-) in sea water Measurement: every 10 minutes Accuracy: + 0.2% relative standard deviation

18. Measurement Cell Dilution Measurement Cell Non Dilution Measurement Cell

19. 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) All Sample Systems are available for all OMNIChem/MINIChem and HANDYChem/ECOChem series analyzers.

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

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

22. 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

23. 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

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

25. Modern Electronics 100 MHz CPU - Hitachi SH3 Series 7708 PC / 32 bit processor 4 MB ROM 2 MB RAM Modbus RTU Touchscreen Interface Unicode/ASCII Up to 57K baud serial communication
