7
Series FH 62 C14Principle of Operation (cont.)

• C14 uses Beta Attenuation through known area on
  filter tape to continuously detect mass of
  deposited ambient particles
• Continuous detection of Beta Attenuation is
  proportional to increased mass
• C14 also measures Alpha particle emissions to
  exclude background interferences from radon gas

8
Series FH 62 C14Principle of Operation (cont.)

• Clean filter spot introduced by automatic filter
  change every 24 hours
• Or sooner if mass on filter exceeds 1500 ?g since
  last filter change
• Or if flow rate is reduced by 5 particle
  deposition
• Ambient air is drawn through a size-selective
  inlet
• TSP, PM10, PM2.5

9
Series FH 62 C14Principle of Operation (cont.)

• Ambient particles are drawn down heated sample
  tube
• Decrease RH of sample stream
• Reduce particle bound water
• Reduces positive artifact measurement of
  condensation on filter tape
• Sample tube is curved to avoid abrupt turns and
  points for premature collection
• Collection of particles on filter tape and
  measured continuously

17
Calibration Procedure and Frequency

• Mass Foil Calibration
• Performed once a year or after measurement
  chamber has been cleaned procedure requires
  20-30 minutes
• Air Flow Calibration
• Performed once a year requires NIST traceable
  volumetric flow device,
• Before Air Flow is calibrated, strongly
  recommended that you calibrate temperature
  sensors and barometric pressure sensors

18
Verification

• Stable operation of instrument is verified and
  monitored by observing Error Status on Main Menu
