Transcript of "Da Vinci DVLS3 Simply, Smart Hydrogen Sensor for Gas Chromatographs"

  1. 1. DVLS³ (S)imply, (S)mart, multi-(S)ensor “Focus on Hydrogen” Exclusive North American Distributor1
  2. 2. DVLS³ (S)imply, (S)mart, multi-(S)ensor 4 Reasons for using H2 as a Carrier Gas1. Fast Analysis:  Fast diffusion rate; 4 times faster than N2  Half as viscous as helium; higher linear gas velocity and shorter retention times2. High Efficiency:  Flattest Van Deemter curve 29 November2 2012
  3. 3. DVLS³ (S)imply, (S)mart, multi-(S)ensor 4 Reasons for using H2 as a Carrier Gas3. Prolonged Column Life: Some applications have a lower elution temperature, therefore the column life is longer4. High Efficiency:  3x’s less expensive than its helium equivalent  Bottle or generator 29 November3 2012
  4. 4. DVLS³ (S)imply, (S)mart, multi-(S)ensor Reluctant to use H2 as a Carrier Gas?  Hydrogen is an Explosive Gas:  Undetected gas leaks can lead to an explosion in the GC Oven  LEL 4% hydrogen in Air 29 November4 2012
  5. 5. DVLS³ (S)imply, (S)mart, multi-(S)ensor Hydrogen Sensor 29 November 5 2012
  6. 6. DVLS³ (S)imply, (S)mart, multi-(S)ensor Sensor Installed in the GC Oven 29 November6 2012
  7. 7. DVLS³ (S)imply, (S)mart, multi-(S)ensor Carrier Gas Switch 29 November7 2012
  8. 8. DVLS³ (S)imply, (S)mart, multi-(S)ensor Sequence Stop after Analysis 29 November8 2012
  9. 9. DVLS³ (S)imply, (S)mart, multi-(S)ensor Calibration Zero Point Calibrated Using Air Alarm level Calibrated using Calibration Mixture Yearly or after maintenance or repair 29 November 9 2012
  10. 10. DVLS³ (S)imply, (S)mart, multi-(S)ensor Alarms Acoustic Optical (blinking display) SMS Message 29 November 10 2012
  11. 11. DVLS³ (S)imply, (S)mart, multi-(S)ensor Catalystic Pellistor Sensor & Wheatstone Bridge 29 November11 2012
  12. 12. DVLS³ (S)imply, (S)mart, multi-(S)ensor Summary & Benefits Catalytic Pellistor gas specific sensor, linear range of 0-2% H2 (0-50% LEL) Unaffected by humidity, stable output for long periods, more resistant to shocks and vibrations. Expected lifetime: over five years Long term stability; drift sensitivity: less than 2mV a month User defined alarm: optical, acoustic and/or SMS up to 50% LEL Instrument readings: provide real time sensor readings with alarm levels, channel states User menu for configuration (password protected) Valve : High pressure 3 way solenoid valve Oven operating temperature: up to 450ο C Multiple Sensors: Max 4 sensors individually controlled Sensor options: temperature, barometer, level, oxygen or hydrogen as a leak detector. 29 November12 2012
