Trace Traces are microscopic amounts of particles and vapors. Narcotic substances are organic and constantly emit ‘traces’. The VaporTracer detects traces down to nanogram levels.
Trace The VT2 is just one more tool to help you improve your ability to detect narcotic traces. Use it along with your X-ray, metal detectors, canine units, physical inspections, and current security measures.

Trace How Do Traces Get Transferred? • Traces cling to anything they touch. • Traces transfer from person to person, person to object, object to object and airborne.
Trace Applications • Cargo, mail, and packages • Conveyance access - Security access points, border crossings, checkpoints • Baggage • Facilities protection - government buildings, correctional institutions
Trace Which of the following can be detected with the VT2? • Gun • Radio lined with narcotics • Pepper spray • Laptop with concealed narcotics • Stun gun • Narcotics traces on a person’s hands
Trace What are some of the traces the VT2 can detect? What are some things the VT2 cannot detect? Are narcotics traces illegal? How are traces transferred?
Sampling • · Particle – Most reliable method. Uses a different collection procedure. • · Vapor – Certain substances give off less vapor than others. Temperature is a factor for collecting vapor. Sample vapor release points.
Sampling Materials and Equipment for Particle Sampling • Sampling Traps • Sampling Wand • Gloves • Sampling Table or Area • Alcohol (isopropyl 70% or greater)
Sampling Materials and Equipment for Vapor Sampling • Vapor Plate • White Spacer • Locking Ring • Check Sample
Sampling Particle Sampling Fundamentals • Person whose item you are sampling should be present. • Sample one item at a time. • Use firm pressure. • Sample in one direction, one time. • Sample most touched areas last.
Sampling Particle Sampling Fundamentals People: • Hands • Belts • Pockets
Sampling Particle Sampling Fundamentals Vehicles: • Door handle • Gas cap • Steering wheel • Knobs • Seat Belt • Luggage • Wherever there may be a fingerprint. • Avoid sampling engine parts.
Sampling Particle Sampling Fundamentals Luggage/Bags/Briefcases: • Handles • Straps • Zipper tabs • Latches • Interior seams and linings • Commonly touched areas
Sampling Particle Sampling Fundamentals Electronic Devices: • Vents • Seams • Battery compartments • Disk drives • Edges • Latches AVOID SAMPLING: • Monitors • Keyboards • Camera lenses
Sampling Vapor Sampling Fundamentals • Sample vapor release points. • Get as close as possible to the vapor release point without touching it. • Temperature affects vapor samples. • Substances emit different levels of vapor.
Sampling What are some particle sampling fundamentals? Vapor? What areas could we sample on a vehicle? Electronic item? Luggage? What areas do we avoid sampling? Why? When do we discard a sample trap?

Equipment Overview • Unit is ready 30 minutes after a cold start. • Unit should be powered-on 24/7. • Default 5 minute warm-up time. • Default 15 minute warm-up time when changing the desorber. • Power down only as directed by pressing the switch to the center position
Equipment Overview Where is the sampling trap placed? Which button takes you to other screens? How long is a cold-start warm up? When do you shut the unit down?
Analysis Procedures • Place the sample trap into the desorber. • Press the Start button to begin analysis. When in Vapor mode, hold the Start button for as long as necessary. Analysis begins when the Start button is released. • Maintain control of the item you are sampling. • Observe Ready or Alarm on the display. • Remove the sampling trap. • If Ready, reuse the trap. If Alarm, discard trap and gloves.
ALARM S-CLR E-SV 10 100 1k 10k COC l 4.13 HER l _ _ THC l _ _ MET l _ _ EDM l _ _ MDM l _ _ Analysis Alarm Response • Resolve the alarm in accordance with current SOP. • Examples: • Contact your supervisor. • Maintain control of item. • Let the owner know that further samples may be necessary. • Decontaminate the work area.
Analysis Saving Alarms • Save the alarm by pressing ENTER. • Clear the unit after saving by pressing START. • Decontaminate the work area with alcohol only • The unit must be cleared before additional samples can be taken.
Analysis Clearing the Unit • Make sure the alarm was saved. • Press the START button when you see Ready on the display. • Insert a new sampling trap and press START. If the new trap alarms, inform the supervisor. • In most cases the unit will clear after an alarm. Otherwise, maintenance may be necessary.
Analysis What is the indication of an alarm? No alarm? What button do you press to save an alarm? What button do you press to clear the unit? What do you do with the trap after an alarm?
Calibration Why Calibrate? • Calibration introduces a known substance into the detector for identification. • After the VaporTracer2 identifies the calibrant, the software will adjust the positions of all substances. • The VaporTracer2 must be calibrated for accurate detection.
Calibration When Do You Calibrate? • After powering up • After changing modes • At the beginning of each shift • When the unit is moved • At higher elevations • When atmospheric conditions change (humidity, pressure)
