1. Mist/Fog particle size 5-100 um
2. Smoke particle size less than 1 um
3. Fume particle size less than 1 um (tend to agglomerate into clusters)
4. Breathing Zone NEW - hemisphere forward of sholders with a radius of 6-9"
OLD - 2' diameter sphere centered on head
5. Systematic Error Correctable error - malfunction of sampler, instrument, or operator -
affects accurancy (not precision)
6. Random Error Unknown/uncontrollable error - random fluctuations of equip-
ment/procedure - affects precision
7. Activated Charcoal organic vapors
8. Silica Gel polar and high-boiling organics/inorganics
9. Porous Polymers (XAD, organic vapors
Tenax)
10. Molecular Sieves, Alumi- polar vapors
na Gel
11. Adsorption one substance just hangs onto the outside of another. Think of people
holding onto a car trolley with one hand and leaning off the side
12. Absorption one substance enters completely into another. Think of people walk-
ing into and sitting down in a car trolley.
13. Solvent Desorption Effi- greater than 75%
ciency (NIOSH)
14. Spectrophotometers

IR - MIRAN, simple organic vapor mixtures, FTIR
UV - Hg detetor
Vis - Halide meter (halogen compounds)
15. Ionization Detectors FID - (flame) general hydrocarbon
PID - (photo) sensitive for aromatic HC, 9-12 eV
16. Catalytic Combustion LEL meter - heated wire - percent level detection - needs O2
17. Electrochemical Cells good for reactive inorganics (O2, O3, NOx, SO2, CO)
18. Flame Photometric De- good for sulfur containing compounds
tectors
19. Gas Chromatography uses various detectors - FID, PID, FPD, ECD (electron capture - chlori-
nated or brominated organics)
20. Nitrous Oxide Tedlar Bag, Portable IR
21. Benzene Tedlar bag, GC-PID
22. Vinyl Chloride Charcoal tube
23. Ketones Charcoal tube
24. Aromatic Hydrocarbons Charcoal tube (PID)
25. Aromatic Amines Silica Gel tube
26. Methylcyclohexanone Porapak Q (porous polymer/bonded phases)
27. Mercury silvered Chromosorb P (impregnated filter/solid)
28. Formaldehyde 2-(benzylamino) ethanol on Chromosorb 102 (impregnated fil-
ter/solid)
