Trace Sampling Equipment Overview Analysis Calibration Course Overview
3
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.
4
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

Traces cling to anything they touch. Traces transfer from person to person, person to object, object to object and airborne. Trace How Do Traces Get Transferred?

Cargo, mail, and packages Conveyance access - Security access points, border crossings, checkpoints Baggage Facilities protection - government buildings, correctional institutions Trace Applications

9
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? Trace

·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

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
25
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? Equipment Overview
26
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. Analysis Procedures
27
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.

28
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 Saving Alarms
29
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 Clearing the Unit
30
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? Analysis
31
Calibration introduces a known substance into the detector for identification. After the VaporTracer 2 identifies the calibrant, the software will adjust the positions of all substances. The VaporTracer 2 must be calibrated for accurate detection. Why Calibrate? Calibration
32
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) When Do You Calibrate? Calibration
