Over 43 years in the IAQ field has enabled us to develop relationships with nationally renown laboratories that specialize in analysis of indoor air quality contaminant samples. Indoor air contaminants that we have experience in sampling and analyzing include:
| Airborne or surface fibers | Carbon dioxide | Mercaptans | PM 10 |
| Aldehydes | Carbon monoxide | Metals | PM 2.5 |
| Allergens | Environmental tobacco smoke | Nitrogen oxides | Sewer gas |
| Ammonia | Formaldehyde / other aldehydes | Ozone | Sulfur oxides |
| Aromatics | Hydrogen Sulfide | PAHs | Surface Dust constituent ID |
| Asbestos | Isocyanates (TDI, MDI, HMDI) | PCBs | Total airborne particulate |
| Bacteria | Lead | Pesticides | VOCs |
