  3. The Mission

  4. What is a chem-ID? The chem-ID is a field gas analyzer • Basically a sniffer • Analyzes gases, liquids with a vapor component, and solids with a vapor component • Core Technology: Two-dimensional gas chromatography with thermal conductivity detectors • Gas chromatography (GC) is the gold standard of chemical laboratories • Before now it has been limited to the laboratory or to field systems that require serious training and expertise • The chem-ID is designed to be easy to use with almost no training required

  5. When would you use a chem-ID? • To analyze unknowns: • Tanker spill • Complaints of odors or people getting sick • Analyze unknown contents of containers, rooms, or vehicles

  6. The chem-ID replaces many tests that require: $100,000 of equipment & 12 feet of bench space A trained analytical chemist

  7. What the chem-ID does well: • Excellent at analyzing individual chemicals in complex clouds • Can analyze chemicals in extremely small amounts (parts-per-billion) • Can analyze and differentiate a large number of different chemicals • Intuitive and easy to use • Doesn’t require a trained chemist to operate • Don’t have to have a specially-trained team to operate and maintain • Allows testing in the field that traditionally required sending samples to the lab • Removes variations caused by high and low temperatures, humidity, wind, altitude

  8. Technology Restrictions • Target chemical has to have a vapor component – does not do solids • Explosives (nitrate-based) typically have very little vapor signature • Very light gases not separated from air • Chlorine, helium, hydrogen, nitrogen, fluorine • Acids

  9. Gas Chromatography vs. other technologies

  10. Introduction

  11. chem-ID Features • Features: • 16 lbs • 16” x 8” x 9” • Performs an analysis by pushing one button • All analysis results are saved in non-volatile memory (won’t erase even if the battery dies) • Can be operated completely by remote control • Chemical analysis can be quickly emailed anywhere • Expanding database can be easily upgraded • Can be decontaminated

  12. chem-ID Controls

  13. Sniffer Port Liquid Analyzer Kit Sniffer Nozzle

  14. The chem-ID Screen

  15. Remote Control Software: chem-ID Manager

  16. What does a chem-ID need to operate? Battery (7+ hours) Reference Chemical (2+ weeks) Helium Tank (2+ days)

  17. Safety Issues • The chem-ID is not Intrinsically safe • Mil Spec 28.8V lithium Battery • Do not Store above 140ºF (60ºC), crush, mutilate, reverse polarity, disassemble, or dispose of in fire. • 2200 psi Helium tank • DoT approved for transport • Tank will change colors if exposed to high temperatures and weakened • Warning label on tank • Reference chemical (aka dopant) is 1,4 dichlorobenzene • Common • Present in very small amount • Wash hands after replacing

  18. Consumables Location Battery Reference Chemical Helium Tank

  19. Consumables: Battery • Battery • 7 hour battery life w/ continual testing, longer if idle or processing data • Rapid battery replacement is provided through the rear door • Rechargeable Li Ion • 14.4 VDC, 8.0 Ahrs • Manual shows installation in step-by-step pictures

  20. Consumables: Helium • Ultrapure He Carrier Gas • Lasts for months in storage • When unit is operational 1 tank can last up to 24 hours of continuous operation • Rapid replacement is provided through the rear door • Can be ordered/ refilled through Laurus Systems • Manual shows installation in step-by-step pictures

  21. Consumables: Reference Chemical • Reference Chemical (dopant) • Small dose in every sample • Used by the chem-ID to automatically calibrate variations of temperature and pressure • Easy replacement in the field • Manual shows installation in step-by-step pictures

  22. Liquid Analyzer Kit Carrying Straps Spare Pre- concentrator CD: Software & Manual PC Bluetooth Radio Kit Battery Helium Tank Storage Reference chemical Recharger Carrying Case and Contents

  23. Instrument Operation

  24. Selecting Test Concentration • Determine the concentration level needed for the test: • Standard (default) or parts-per-billion (ppb) • Standard test level is sufficient in almost all situations • If you do a ppb test in a high concentration environment, the unit may need multiple manual clean cycles to finally clean out • Perform tests at standard concentration unless… • You are analyzing a chemical at ppb levels • A chemical presence is strongly suspected without any overt evidence (i.e. no liquids, no odors)

  25. Checklist • Test Checklist • Turn on Unit • Open front and back vents • Open Helium valve • Check Helium gauge for at least 300 psi • Press Analyze button

  26. 1. Turn On Unit On/Off Rocker Switch

  27. 2. Open Vents Front Twist Knobs to Point at Open Back

  28. 3. Open Helium Valve Open Panel Twist Helium Knob all the way open (in the direction of the arrow on the knob)

  29. 4. Check Pressure Gauge Pressure Gauge Need 300 PSI or more

  30. 5. Press Analyze Button Button Labels Press Middle Button to Start Analysis

  31. The chem-ID will tell you… • If the battery is too low to begin an analysis • If the helium is too low to begin an analysis • If you forget to open the front or back vents • If you need to add more reference chemical

  32. What the unit is doing during Analyze • Automatically goes through the following phases: • Warm-up • Draws an air sample • Prepares the sample • Performs the analysis • Displays raw data in real-time • After analysis is complete, replaces raw data with processed data and shows identifications • Purges and cleans • Cool down to prepare for next test Overall Status Status of this Phase

  33. Gas Chromatographs During Analyze, this graph will be slowly drawing Raw Data is not very useful, but shows the unit is busy After the raw graph is done, it will be processed and replaced with this graph This is the real chromatograph

  34. Identifications

  35. Identification Database

  36. Database • Early focus is on TICs • Expanding database: • More TICs • CWAs • Hydrocarbons • Common interferents • Meth Lab variant

  37. Currently in Chem-ID™ ID Library

  38. Future Library Expansions

  39. Chemical Warfare Agents Hydrogen Cyanide (AC) Soman (GD) Lewisite (L) Cyanogen Chloride (CK) Mustard Gas (HD) Tabun (GA) Sarin (GB) Nit. Mustard (HN1,2,3) Interferents Antifreeze Clorox Kerosene Burning cardboard Diesel White vinegar Burning cotton Gasoline Windex Meth Manufacturing Chemicals a-benzyl-N-methylphenethylamine Dibenzyl ketone Nitroethane Acetic acid Diethylmalonate Phenyl-2-propanone Aluminum oxide Dimethylformamide Phenyl acetic acid Amphetamine Ephedrine phosphorous Benzyl chloride Ethyl acetate Sodium carbonate Benzyl cyanide Mercury Sodium hydroxide Benzyl methyl ketone benzylimine Methylamine Tri-(-phenylisopropyl) amine Di-(1-phenylisopropyl) amineN,N-dimethylamphetamine Future Library/Category Expansions

  40. Identification Confidence • When identification of an unknown chemical shows several possibilities, the confidence bar shows which identification is closest to the database Unknown chemical could be Xylene or Ethyl Benzene Confidence Bar

  41. Remote Operation

  42. What can be done with the chem-ID Manager? • Control the chem-ID remotely up to 100m away • Download test results to the PC • Study and compare test results on a PC (bigger screen, easier controls, more comfortable environment) • Convert chromatographs into CSV format (read by Microsoft Excel) • Update clock on chem-ID easily • Update firmware on chem-ID easily • Update identification database easily

  43. You will need • A PC with Windows XP  or Vista  • In the chem-ID kit • chem-ID Manager Software • USB Bluetooth radio and installation CD • Installation • Bluetooth radio • Install as per the enclosed instructions • chem-ID Manager • Put CD in drive and open PC Manager directory

  44. Turn on Bluetooth radio in the chem-ID • Under the Menu button: • Menu • Settings • Communication Port: Bluetooth Bluetooth Logo means the radio is on

  45. First get Windows Bluetooth talking to chem-ID Bluetooth • 1. In Windows, select Bluetooth icon and tell it to search for Bluetooth devices nearby (or search Bluetooth neighborhood). • 2. Select chem-ID and tell it to connect

  46. Windows Bluetooth talking to chem-ID Bluetooth cont. It will ask for a passkey. Passkey is always 00000000 (8 zeros) When the connection is established, Windows will tell you the port (com4 for example)
