Technology
• Power of lamp measured in electron volts (eV)
• eV rating of lamp must be higher than eV potential
of compound (found in NIOSH guide) for
compound to be detected

Selectivity
Technology
• PID’s are not selective in which compounds they
detect
• Apply the correct response factor to the reading
• Need to consider:
– What VOC’s am I likely to see?
– What of these has the lowest Permissible Exposure
Limit?
