TO-1

• Handling
• Hold the middle of the tube (DO NOT hold ends)
• Oils from fingers could cause contamination
• Storage/Shipping
• Keep tubes refrigerated
• DO NOT allow tubes to get wet
• Ship in cooler with ice
• seal in zip-lock bags
• Shipping Container
• No storage container

TO-1

• Sampling
• Remove the Swage lock fittings
• Attach a pump tubing to one end of the tube
• Sample Volume
• Total volume range 18-20 liters
• Should NOT exceed 20 liters

Pump Calibration

• Introduction
• Should be conducted in controlled work area
• Should be conducted before and after each
  sampling episode
• Must use a calibration tube

16
Pump Calibration

• Pre-Sampling Calibration Procedure
• Record calibration data on the field data sheet
• Connect the calibration sampling tube
• Connect other end of sample calibration tube to
  the calibrator
• Insure sufficient level of bubble solution
• Turn pump on
• Depress and release the black button on the
  calibrator
• Observe the pump flow

17
Pump Calibration

• Pre-Sampling Calibration Procedure
• Turn the fine adjustment to achieve desired flow
  rate
• TO-1 Flow Rate - 39.5 ml/min
• TO-17 Flow Rate - 39.5 ml/min
• DAMMS Flow Rate - 39.5 ml/min
• Take 3 - 5 readings and record average as Flow
  Rate Pre
• Post Sampling Calibration procedure
• should be the same
• except with NO FLOW ADJUSTMENT
• Take 3 - 5 readings and record average as Flow
  Rate Post

Programming the Pump

• Introduction
• If unit is programmable, USE THE PROGRAMMER
• Pump can be programmed for a delayed start
• Ensures primary and co-located pumps start at
  same time
• Allows for programming to be conducted off-site
• Programming the SKC Pump
• Initializing Programming
• Turn pump on
• Press START/HOLD
• Press SET UP

20
Programming the Pump

• Programming the SKC Pump
• Programming Delayed Start
• Determine the delayed start time and duration of
  sampling
• Press MODE until Delayed Start is displayed
• Set DELAY START using the digit select and digit
  set buttons
• Programming Sample Period
• Determine sample period
• Press MODE until Pump Period is displayed
• Set PUMP PERIOD using the digit select and digit
  set buttons

21
Programming the Pump

• Programming the SKC Pump
• Toggle through the Delayed Start, Sample
  Period, and Pump Period to ensure correct
  times have been set
• Press START/HOLD
• Places unit in HOLD mode
• Once in HOLD mode, sampler will begin count
  down
• When delayed start has reached zero the sampler
  will start

Quality Assurance/ Quality Control Procedures

• Note in the Invalid Sample field the
  appropriate code of sampler malfunction or filter
  damage

  everything in the book, send it back to CHPPM

32
Packing Samples for Shipment

• Filters should be replaced in their respective
  petri dishes and sealed.
• Include enough packing material in shipping box
  to ensure that filters do not move in shipping
  container.
• Tubes MUST NOT GET WET!
• Put tubes in sealed plastic bags
• Keep at 4oC

33
Sample Shipment

  collection dates of samples.
• Lab analysis request form, chain of custody form
  and soil importation permit placed inside cooler
• Soils importation form and chain of custody seal
  affixed to exterior of cooler.
• Packing materials
• Ice chest or other packing container
• mark Environmental Samples,
• This end up, "U.S. Government
• Property", etc.
• Freezer packs (4 degrees Celsius )

  commercial carriers.
• Talk with the shipper before collecting the
  samples.
• Do not send Hazardous Materials by U.S. Mail.
